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.
Banana & Chocolate Marble Loaf Cake
1 15.25 box yellow cake mix (I used Duncan Hines)
eggs, water & oil per directions on box
1 ripe banana, mashed
2 tablespoons cocoa powder
Preheat the oven to 350 F. Spray a 9×5-inch loaf pan with baking spray and set aside.
Prep the cake mix per the instructions on the box.
Divide the batter in half and stir the mashed banana in one half and the cocoa powder in the other.
Spoon the batters into the prepared pan, alternating between the two. Use a knife to swirl the batters together. Tap the pan on the counter a few times to remove any air bubbles.
Bake for 40-45 minutes, or until a cake tester inserted in the center comes out clean.
Let the cake cool in the pan for 15 minutes then transfer to a wire rack to cool completely.
Store leftovers in an airtight container at room temperature.
