This cake is very similar to the Banana & Chocolate Marble Loaf Cake I recently posted about. The only difference, you guessed it, is that I swapped peanut butter for banana. I think we can all agree that peanut butter and chocolate go together perfectly, if not, Reese’s Peanut Butter Cups would have been off the market years ago. That reminds me, my favorite Reese’s Peanut Butter Cups are back in stores, the Easter Egg ones. I don’t know what it is about those, but they just taste better. Maybe it’s because they don’t have the ridges that typical peanut butter cups have due to the wrapper they are in. Who knows! Back to today’s cake…
Once again, I used a yellow cake mix as the base for this loaf cake. After prepping the batter I divided it in half and mixed cocoa powder in one half and creamy peanut butter in the other. I used a 1/4 cup of peanut butter, but if you want a stronger peanut butter flavor, I suggest using a 1/3 cup. I then spooned the batter into my prepared loaf pan to create the marble effect.
After baking it I let it cool in the pan for a few minutes before transferring it to a wire rack to cool completely. And then it was time to slice and enjoy!
Not too long ago I posted a recipe for a Peanut Butter & Banana Chocolate Chip Bread. That got me thinking about making a marble cake using two of the flavors. After some brainstorming I thought that a super simple way to do so would be to use a yellow cake mix as the base and altering the flavor with some add-ins. Now, I know some people have issues with using box cake mixes, but it really is possible to alter them to make them taste more homemade and they are fool proof! This all led me to creating a few recipes that use cake mixes as their base. And I will be sharing them with you over the next week… Up first, a Banana & Chocolate Marble Loaf Cake.
For the base of this loaf cake I used a yellow cake mix. After prepping the batter per the directions on the box I divided it in half. And to be precise, even though I have made plenty of box cake mixes in the past and had a rough idea of how much it was, I measured out the batter using a measuring cup. In total it was 4 cups, so I transferred 2 cups to a bowl and stirred in a mashed banana and in the other half I stirred in 2 tablespoons of cocoa powder.
Next, I dropped alternating scoops of each batter into a loaf pan I sprayed with baking spray. To get the marble effect I swirled the two batters together by dragging a knife through them.
After baking and cooling the cake, it was time to enjoy a slice (or two!) As for the flavor, the chocolate and the banana really stood out without either overpowering the other. A nice twist on your typical marble cake.
A few takeaways… To make chocolate cake from a yellow cake mix you can add a few tablespoons of cocoa powder and to make a super simple banana cake add mashed banana to a yellow cake mix. More specifically, 4 tablespoons of cocoa powder for a chocolate cake and 2 mashed bananas for a banana cake.
