I admit I’ve scooped several cartons of cookies ‘n’ cream ice cream, taking the Oreo chunks and leaving behind the vanilla ice cream. I’ve seen other people maim crumb cake, slowly picking at the top until it resembles a giant network of holes. It’s all for the love of chunky bits. Tell me, what’s the latest topping/mix-in that you’ve picked at?

For all of us chunk stealers, I wanted to make a coffee cake that would never run out of bits, no matter how many times you picked at it. I started with seasonal apples, added chocolate (because everything tastes better with chocolate), then walnuts and streusel. To keep the batter light, I first looked to a butterless, eggless recipe in the Joy of Cooking. While it could easily be veganized (substitute the buttermilk with soy milk and apple cider vinegar), it actually had more sugar and fat than the regular recipe.

Vegetable oil is a “good” fat, but if you use a lot and it doesn’t have any flavor, it’s not worth it. I’d rather use a small amount of the good stuff. So, eggs and butter were back in. Traditional cakes get their light texture by whipping air into butter and sugar. Then eggs are added, just until they are incorporated. Since this recipe doesn’t have a lot of butter, you instead beat the heck out of the eggs, until the mixture becomes light and fluffy.

All the mix-ins balance out the lean cake. If you’re looking for something lighter, you can omit the streusel topping (see the variation below) or chocolate chips. Don’t be scared by all the steps below; they’re only there because of all the goodies.

Chunky Chocolate-Apple Coffee Cake

This over-the-top cake gets its chunks from apples, walnuts and chocolate chips. The streusel sinks into the cake and resembles soft cinnamon bun filling.

Adapted from recipes and techniques from The Joy of Cooking, Coffee Cakes and Chocolate and the Art of Low-Fat Desserts

For the cinnamon streusel:
1/3 cups Grape-Nuts cereal
1/3 cup lightly toasted walnuts, coarsely chopped
1/3 cup packed brown sugar
2 Tbsp all-purpose flour
1 tsp ground cinnamon
1 egg white
1 Tbsp unsalted butter, melted
1/4 tsp vanilla

For the cake:
2 cups all-purpose flour
1 tsp baking powder
1 tsp baking soda
1/2 tsp salt
2 large Golden Delicious apples, peeled, cored and diced into half-inch cubes (about 2 cups)
2/3 cup chocolate chips
1 cup plain yogurt, buttermilk or sour cream
1 tsp vanilla
5 Tbsp (1/2 stick plus 1 Tbsp) unsalted butter, at room temperature
1/2 cup packed brown sugar
1/2 cup granulated sugar
2 large eggs

1. Position a rack in the lower third of the oven. Preheat the oven to 350F. Grease and flour a 9″-round springform pan.
2. To make the streusel:
   • In a small bowl, stir together the Grape-Nuts cereal, walnuts, sugar, flour and cinnamon.
   • In a separate bowl, beat together the egg white, butter and vanilla.
   • Stir the egg white mixture into the cereal mixture with a fork. Cover and refrigerate.
3. In a medium bowl, whisk the flour, baking powder, baking soda and salt together. Set aside.
4. In another medium bowl, toss the apples and chocolate chips with 1 Tbsp of the flour mixture. This way, they won’t sink to the bottom of the cake.
5. In a small bowl or cup, combine the yogurt (or what you have chosen) with the vanilla and set aside.
6. In a large bowl (the last one, I promise), cream the butter with an electric mixer until soft, about 1 minute. Add the sugars gradually, beating for about 3 minutes. Beat in the eggs, one by one, at medium-high speed until light colored and airy, about 2 to 3 minutes.
7. Add the flour mixture in three parts, alternating with the liquids in two parts, beating on low speed or stirring until smooth and scraping the sides of the bowl with a spatula as necessary. Just before the batter comes together, gently stir in the apples and chocolate chips.
8. Scrape the batter into the pan and spread evenly. Evenly sprinkle the top with large dollops of streusel.
9. Bake for 45-60 minutes, or until the edges are brown and a toothpick inserted in the center comes out clean (except when touching the apples and chocolate chips). Cool the cake on a rack for 15 minutes, then unmold. Serve slightly warm or at room temperature. Serves 12.

Variations:

Whole wheat coffee cake: Substitute 1 cup whole-wheat flour for 1 cup of all-purpose flour.

Simplified: Omit the streusel and add 1 tsp cinnamon to the flour mixture. Sprinkle the top of the batter with 1/2 cup toasted, coarsely chopped walnuts.

Notes:
This is an experimental recipe. I used a couple tablespoons more buttermilk than called for, and the middle took a long time to cook while the edges got dry. That’s why I reduced the liquid to one cup. I also only baked half a cake for 45 minutes, so the cooking time above is an estimate. My oven loses heat quickly, so it should take you less time. I also only used half a stick of butter, and my edges were slightly rubbery (the result of gluten formation and over baking). The extra tablespoon of butter should do the trick.
