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!
Peanut Butter & Chocolate Marble Loaf Cake
1 15.25 box yellow cake mix (I used Duncan Hines)
eggs, water & oil per directions on box
1/4 cup creamy peanut butter*
2 tablespoons cocoa powder
*If you want a stronger peanut butter flavor use 1/3 cup
Preheat the oven to 350 F. Spray a 9×5-inch loaf pan with baking spray and set aside.
Prepare the cake mix per the instructions on the box.
Divide the batter in half and stir the peanut butter in one half and the cocoa powder in the other.
Spoon the batters into the prepared one, alternating between each one. Use a butter knife to swirl the two batters together and tap the pan on the counter a few times to remove any air bubbles.
Bake 45-50 minutes in the preheated oven, or until a cake tester inserted in the center comes out clean.
Cool the cake in the pan for 15 minutes before removing and transferring to a wire rack to cool completely.
Store leftovers in an airtight container at room temperature.
