This semi-homemade recipe is a true winner. A few simple ingredients are combined with a basic cake mix for a light and lovely dessert. Oats, brown sugar, and walnuts are combined to make a tasty crumble. While, eggs, sour cream, bananas, and a few extracts are combined with a basic cake mix to form a simple batter. I stock overly ripe bananas in my freezer for just such an occasion. All of these ingredients are layered into a tube pan to make a beautifully textured cake.
Banana Crunch Cake
½ cup flour
1 cup rolled oats
¾ cup firmly packed brown sugar
½ cup chopped walnuts
½ cup margarine or butter
1 ½ cups (2 large) very ripe bananas, mashed
½ cup sour cream
1 teaspoon butter extract
1 teaspoon vanilla extract
1 yellow or white cake mix
Heat oven to 350 degrees. Grease and flour a 10″ tube pan. In medium bowl, combine flour, rolled oats, brown sugar and pecans; mix well. With fork or pastry blender, cut in margarine until mixture is crumbly. Set aside.
In large bowl, combine bananas, sour cream, extracts and eggs; beat at low speed until smooth. Add cake mix; beat until fully combined. Spread 1/3 of batter in prepared pan; sprinkle with 1/3 of brown sugar crumble mixture. Repeat layers 2 more times using remaining batter and brown sugar mixture, ending with brown sugar mixture.
Bake for 45-50 minutes or until toothpick inserted near center comes out clean. Cool upright in pan 15 minutes. Remove cake from pan; place on serving plate, crumble side up. Cool completely before serving. Sprinkle with powdered sugar, if desired.
