banana peanut butter chocolate chip cake

yes, you read that title right. why haven't i thought of this or seen it before? what could be better? those three flavors in combination just feels RIGHT. you know what i mean? i saw a recipe for it here via foodgawker. i didn't have peanut butter chips or cinnamon chips, so i'll write up the recipe the way i made it and you can look at the original here.

4 very ripe bananas
2 large eggs
1 ½ cups unbleached all-purpose flour
1 cup granulated sugar
1 tsp. baking soda
2 tsp. ground cinnamon
1 tsp. pure vanilla extract
3/4 cup peanut butter
2 cups chocolate chips

for topping:
3 Tbsp. granulated sugar
1/4 tsp. ground cinnamon
approx. 1 Tbsp. brown sugar

preheat the oven to 375 degrees fahrenheit. grease an 8-inch square pan. in a medium mixing bowl, mash the bananas well with a fork or potato masher. add the eggs, and stir well to combine. add the flour, sugar, baking soda, cinnamon, and vanilla, and stir to mix. add the peanut butter and when that is combined, add the chocolate chips. pour the batter into the prepared pan, and set aside. in a small bowl, stir together the cinnamon and granulated sugar. sprinkle the mixture evenly over the batter in the pan, then sprinkle brown sugar over the top. bake for 35-40 minutes (it took me longer so just be aware it might take more time), or until a toothpick inserted into the center comes out clean. let cool in the pan on a wire rack for at least 15 minutes before serving.
