By now I’ve made cakes from avocado, beets, and potatoes, so a dessert with zucchini sounds relatively ordinary. But if we forgo zucchini bread, then we can have some fun.

I found a recipe for zucchini blondies after seeing a surplus of the squash at my market. (Since when is zucchini “in season” in the spring? Should I be worried?) It sounded strange, but I had a lot of zucchini, and it gets boring and mushy when you sauté it the traditional way.

This recipe was surprisingly good (believe me, I don’t like everything I make). Because the zucchini adds moistness, these blondies are extra gooey and virtually impossible to over bake. Just be sure to chop the zucchini very small, as the recipe instructs. Otherwise, the blondies will seem overly vegetal. For you fainthearted, I’m sure you could substitute bananas, which would go well with the butterscotch-like batter.

Zucchini Blondies

Adapted from Smith & Hawken: The Gardeners’ Community Cookbook by Victoria Wise

Oil or soft butter, for greasing the baking pan
5 tablespoons butter, melted with 1 tablespoon water
1 cup (packed) dark brown sugar
1 large egg
1 teaspoon vanilla extract
1 cup all-purpose flour
1 teaspoon baking powder
1/8 teaspoon baking soda
1/2 teaspoon salt
1 medium zucchini, peeled and chopped into 1/4-inch pieces (6 ounces)
1/2 cup coarsely chopped walnuts or pecans
1/3 cup chocolate or butterscotch chips

Preheat the oven to 350°F with a rack in the middle. Lightly grease a 9-inch square baking pan.

Pour the melted butter into a large mixing bowl. Add the sugar and mix well. Add the egg and vanilla, and beat until blended.

Whisk the flour, baking powder, baking soda, and salt in a medium bowl. Add to the butter mixture. When almost combined, stir in the zucchini and nuts to make a stiff batter.

Spread the batter in the baking pan and sprinkle the chocolate chips on top. Bake for 30 minutes, or until a toothpick inserted in the center comes out almost clean with a little batter clinging.

Remove from the oven, and when cool, and slice into 16  squares. Serve warm or at room temperature. Keeps, covered, for 3 days at room temperature. Or wrap each piece individually and freeze for longer.

Sorry to invoke wrath of Southerners, but red velvet is not a cake flavor. It’s a fancy name for a neon novelty. According to legend, the color comes from the chemical reaction of cocoa powder and acid (nowadays, we enhance it with food coloring). That doesn’t sound right, because most recipes only have two tablespoons of cocoa, which isn’t enough to cause a huge change in hue, much less chocolatiness.

Even though the FDA says that food coloring is nontoxic, I have second thoughts when I have to dump a whole bottle of red #40, ground beetles, or whatever into a cake. I’d rather use non-lab produced ingredients, like beets. And seriously, why so stingy with the cocoa?  The cake has to taste like chocolate.

I found a recipe that satisfies both criteria: it’s from the American Cancer Society’s Taste More Birthdays Cake Contest.  As the name suggests, it’s semi healthy with less sugar and fat but plenty of vegetables, fruit, and whole grains. The ingredients sound strange, but the earthiness of the beets goes well with the chocolate, and the fruits add tartness. Just tell your friends that you made chocolate-raspberry cake, and they won’t have to know your secret. It’s so moist and rich that I don’t think it needs frosting. My only complaint is that it loses its bright red color after it comes out of the oven.

I adapted the recipe so the prep time’s cut in half (using canned beets saves more than two hours). I also changed the dried fruits so it’s less expensive.

New Red Velvet Cake

Adapted from Alexandra Mudry
(Recipe will make 1-9×14” cake, two 8” round cakes or 24 cupcakes)

Cake:
1 1/2 15-oz. cans unseasoned beets (to make 2 c. purée)
1/2 c. dried dates, pitted and coarsely chopped
1/2 c. prunes, coarsely chopped
1/2 c. applesauce, unsweetened/natural
1 c. granulated sugar
1/2 c. canola oil
3 large eggs
3 oz. unsweetened chocolate, melted
1 tsp. instant espresso powder or instant coffee
1/2 c. unsweetened natural cocoa powder (not Dutch-processed)
1 c. all-purpose flour
3/4 c. whole wheat flour
1 1/2 tsp. baking soda
1/2 tsp. salt

Place beets in a blender or food processor with 2-3 tbsp. water. Purée beets until they’re smooth throughout. Blend in the dates and prunes. Set aside. (Can be made several days ahead and stored in an airtight container in the refrigerator.)

Preheat oven to 375° F. Spray baking pan(s) with canola oil spray and dust with flour. Discard the excess flour (or if making cupcakes, line tins with paper wrappers).

Combine the oil, eggs and sugar in a mixing bowl. Beat with an electric beater on medium speed until smooth and light colored.

Add the espresso powder to the melted chocolate and stir until combined.

Turning the speed down to low, slowly drizzle the melted chocolate into the mixture. Once the chocolate has been added, turn off the machine and scrape the sides of the bowl.

In a separate bowl, combine the cocoa powder, applesauce and beet purée. Add this mixture to the egg mixture. Beat on medium speed to incorporate.

Sift the remaining dry ingredients together and then gently fold into the mixture (don’t overmix or the cake will become tough).

Pour batter into the pan(s) and bake for 40-45 minutes (or 20-25 for cupcakes), or until a toothpick inserted in the center comes out clean.

Cool and remove from pan(s). If not using immediately, wrap in plastic wrap and refrigerate. Cake can be made a day in advance. (The cake is delicate and crumbly so it’s much easier to work with once chilled. )

Cream Cheese Frosting (optional):
24 oz. (3 pkgs) reduced fat cream cheese, room temperature
1 1/4 c. confectioners’ sugar, sifted
2 tsp. vanilla extract

Lightly beat the cream cheese and vanilla with an electric mixer until smooth, about 1-2 minutes.

Scrape down sides of bowl then add confectioners’ sugar. Cream together until smooth. Don’t overmix or the frosting will become too soft and difficult to spread.

Assembly:
If using a 9” x 14” pan, cut the cake lengthwise down the middle so you have two layers.

Cover with cream cheese frosting.

Serves 10-12 generously.

The first time I tried avocado in a dessert, it was in a milkshake at an eclectic restaurant. I loved avocados; I loved sugar. Why not? Then my cousin pointed out, “Ew! You’re going to drink pure fat!” By the time the shake came, I could only muster a sip. My mom, ever the good sport, finished it for me.

Ten or so years later, I encountered an avocado Popsicle at the New Orleans farmers market. By now I knew that avocados were common in Southeast Asian and Latin American desserts and wasn’t grossed out. This Popsicle was like ice cream on a stick; it was refreshing on that blistering day.

When my aunt recently visited me, she brought along gifts: Harbor Sweets chocolate, Trader Joe’s freeze-dried mangosteens, lettuce and avocados. (She was just being practical with the veggies.) That avocado was getting softer by the day, and like all surplus food, I had to turn it into dessert. I almost went with avocado pancakes, but they’re savory. So I went with this tender cake from Accidental Hedonist. As Kate says, “Done correctly, it’s a cake that can sit with pride next to your zucchini bread or pumpkin cake.” It doesn’t taste gross, but it’s faintly vegetal in a good way, like carrot cake.

It’s so good that I might substitute puréed avocado for butter in other recipes. It’s kind of healthy too: avocado’s high in omega 3s, vitamin E and fiber. If you’re worried that people will be put off by the green color, just tell them you made a pistachio cake, which sounds far fancier. Trust me, it’s worth saving your avocados for.

Recipe is at Accidental Hedonist
You can skip the walnuts and dried fruit if you wish. To make 20 cupcakes, bake for about 20 min. in a 350° F oven.

The things people bake these days: cake with pork and beans and tomato soup!  Scary ingredients, yes (why would you use canned soup when fresh tomatoes are falling off the vine?), but scary concept, no.

If you like carrot cake, fudgy brownies (with a secret ingredient), or zucchini bread, Carole Walter’s tomato cake isn’t far off.  For the best results, use heirloom tomatoes.  The uglier the better.  You won’t taste the tomato, but instead you’ll get a moist “spice cake.”  It is one of my favorite cakes, and it has relatively little butter.  Sorry, no pictures.  I made this a couple years ago.

Sugarsweet Tomato Nut Torte

Recipe from Great Cakes by Carole Walter

(Serves 8 to 10)

3/4 pound very ripe tomatoes
1 tablespoon cider vinegar
1 1/2 cups walnuts
1/3 cup (2/3 stick) unsalted butter
1/2 cup unbleached all-purpose flour, unsifted
1 cup sifted unbleached all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
1 teaspoon ground cinnamon
1/2 teaspoon ground nutmeg
4 large eggs
1 1/4 cups dark brown sugar, lightly packed
2 teaspoons freshly grated navel orange rind (optional)
1 teaspoon vanilla extract

1. Cut an X in the skin on the bottom of each tomato. Remove the cores, place the tomatoes in a bowl and add boiling water to cover. Allow to stand for 1 minute, then rinse in cold water and peel off the skins. Cut each tomato in half across the core and squeeze gently to remove seeds and juice. Puree the pulp in a food processor. You should have about 1 cup of puree. Stir in the vinegar and set aside.

2. Position a rack in the lower third of the oven and preheat to 325 degrees. Butter a 9-inch springform pan and line the bottom with parchment paper.

3. Put walnuts and 1/2 cup unsifted flour in the container of the processor fitted with the steel blade and pulse 8 to 10 times, until nuts are chopped to medium size. Transfer to a bowl and set aside.

4. In a small pan, melt the butter over low heat. Set aside to cool to tepid. Sift together the 1 cup sifted flour, baking soda, salt, and spices in a triple sifter. Set aside.

5. Place the eggs in the large bowl of an electric mixer fitted with beaters or whip attachment. Beat on medium-high speed until thickened and light in color, about 1 1/2 to 2 minutes. Gradually add the brown sugar over 2 to 3 minutes and beat for 3 minutes longer. The mixture will be very thick.

6. Reduce mixer speed to medium-low. Blend in the orange rind and vanilla. Add the flour mixture alternately with the tomato puree, dividing the dry ingredients into 3 parts and the puree into 2 parts, starting and ending with the flour. Scrape sides of bowl as needed. The batter will be very loose.

7. Quickly pour in the butter, then add the nuts, beating just until blended.

8. IMMEDIATELY pour the batter into the prepared pan. Center the pan on the rack and bake in the preheated oven 55 to 60 minutes, until cake is golden brown, springy to the touch, and the sides, begin to come away from the pan. A toothpick inserted into the center should come out dry.

9. Remove from oven and set the pan on a cake rack to cool completely. Release the outer rim of pan, invert the cake onto the rack, and peel off the parchment paper. Place top side up on a serving platter. Just before serving, dust the top with confectioners’ sugar. If you like, split the cake into two layers with a long thin knife, then fill and frost with Whipped Cream made with 1 1/2 cups heavy sweet cream. Garnish with chopped walnuts.

I love potatoes so much that if I were to list the ways I eat them, I would sound a lot like Bubba in Forrest Gump:

Anyway, like I was sayin’, potatoes are the fruit of the earth. You can fry them, bake them, boil them. There’s uh, potato salad, mashed potatoes, screaming potatoes, potato pancakes, potato bread, potato dumplings, potato sticks, potato gratin, criss-cut fries, cream of potato soup, potato curry and potato cake. That—that’s about it.

By cake, I don’t mean latkes. I mean dessert. Mashed potatoes make moist bread, like Nutella babka, but I’d never tried it in cake. I wanted to add it to a favorite chocolate cake recipe, but I wasn’t sure whether it would replace the fat or the flour (because it’s creamy and starchy). Off to the Internet I searched. Some recipes had virtually no chocolate, while others had too much butter. This one, from I Love Chocolate, seemed the most reasonable. Since I didn’t have the Dutch-process cocoa it called for, I used natural cocoa and tinkered with the leavening. Besides, I think natural cocoa has a more complex flavor.

The resulting cake was light and moist. I didn’t think it was chocolatey enough, but maybe it’s because I forgot to add the vanilla. Paired with vegan chocolate frosting, this cake will cause tasters to do a double double-take. It’s an unusual dessert for St. Patrick’s Day, because it doesn’t scream green (or Guinness). If you really want to go green though, Gourmet.com has plenty of ideas, like apple celery granita. (Dang it, just click on the link because I built the slideshow while fighting a cold.)

Irish Chocolate-Potato Cake

Cake adapted from Stephanie Zonis. Frosting adapted from More Great Good Dairy-Free Desserts Naturally by Fran Costigan.

For cake:
2 medium or 1 large potato (to make 1 cup hot, unseasoned mashed potatoes)
2 tsp instant espresso or coffee granules, dissolved in 1 cup hot water
2 cups sifted all-purpose flour
3/4 cup unsweetened natural cocoa powder (not Dutch-processed)
2 tsp plus a pinch of baking soda
1/2 tsp salt
1 stick plus 2 tablespoons unsalted butter, softened
2 cups granulated sugar
1 tsp vanilla extract
4 large eggs

For frosting:
(Makes 2 cups, enough to fill and frost one 9-inch two-layer cake)
Tofu frosting without chocolate is too watery and beany for my tastes. This one, which resembles mousse, is a keeper.

1 (12.3-ounce) aseptic box firm silken tofu (recommended brand: Morinu)
1 tablespoon plus 1 tsp canola oil
1/3 tsp salt
1/4 cup sugar
1/4 cup unsweetened cocoa
1 heaping tsp vanilla extract
6 ounces (about 1 cup) semisweet or bittersweet chocolate, melted
1-3 tablespoons chocolate, vanilla, or plain soymilk, if needed

Equipment: potato ricer/food mill or a fine-mesh sieve, food processor, 9-inch round cake pan, serrated knife, icing spatula

Make mashed potatoes: Boil or steam the potatoes until fork tender, about 15 minutes. When the potatoes are cool enough to handle, peel off the skin. Pass the potatoes through a potato ricer/food mill. Or mash them with a fork and push the mixture through a fine-mesh sieve to get rid of the lumps. (You can make the mashed potatoes a couple days ahead of time.)

Make cake: Position a rack to center of the oven; preheat oven to 350 degrees F. Grease 9-inch round pan with butter. Lightly flour the pan, knocking out any excess flour; set aside.

Place mashed potatoes into a medium bowl. With a small whisk, gradually stir in coffee to form a smooth mixture; do not beat mixture excessively. Cool to lukewarm.

Meanwhile, sift together flour, cocoa powder, baking soda and salt. Set aside.

In large bowl, combine the butter, sugar and vanilla with an electric mixer. Beat at a low speed to blend, then beat 2 minutes at medium speed, scraping down bowl and beater(s) with rubber spatula once or twice. Add eggs, 2 at a time, beating in at a low speed until blended. Scrape bowl and beater(s) with rubber spatula. Increase mixer speed to medium; beat 1 minute.

At lowest speed, add sifted dry ingredients in 3 additions and mashed potato-coffee mixture in two additions, beginning and ending with dry ingredients and beating after each addition just until blended. Scrape bowl and beater(s) occasionally with rubber spatula. Batter may still appear curdled after all ingredients have been added.

Pour batter into prepared pan and spread evenly. Bake in preheated oven about 1 hr, rotating pan 180 degrees during baking. Cake is done when toothpick inserted near center emerges with a few moist crumbs still clinging to it. Remove to cooling rack.

During baking, cake center will rise higher than edges, but center will fall slightly as cake cools. Cool completely before frosting. Store at room temperature, covered airtight, for up to 3 days; freeze for longer storage.

Make frosting: Combine the drained tofu, oil, and salt in a food processor, and process about 1 minute until pureed. Use a rubber spatula to clean the sides of the bowl and add the sugar, cocoa, and vanilla. Process 1 to 2 minutes, until the tofu mixture is smooth.

Add the melted chocolate and pulse the processor three or four times to incorporate. Process 1 to 2 minutes until the mixture is very creamy. Refrigerate in the processor for 20 minutes. The cream may need to chill for 1 to 6 hours in order for it to become firm enough to spread.

The degree of firmness will determine the amount of soy milk needed to create the final texture. It should be thick but easy to spread. Dip an icing spatula into the cream to test to the texture. If the cream is too stiff to use, add 3 tablespoons of the soy milk and process 1 minute. Add more soy milk, 1 tablespoon at a time as needed. When the cream is ready to use, spoon it into a bowl and begin to assemble the cake.

Frost the cake: With a serrated knife, level off the top of the cake. Cut the cake into two even layers. (Need more detailed instructions?) Cover one layer with frosting, then add the top layer. Frost the top and sides.
