COOK TIME: 25 Min

The combination of peanut butter and bananas in this easy cake recipe makes it sinfully divine. Don't be surprised at how fast this Banana Peanut Butter Cake will disappear!

What You'll Need

3/4 cup all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon baking soda
1/4 teaspoon salt
1/4 cup margarine, light, softened
1/3 cup sugar
1 egg
1/4 cup reduced-fat peanut butter
2 tablespoons reduced-fat sour cream
1 large ripe banana, mashed

What to Do

Preheat the oven to 350 degrees. Coat an 8-inch round cake pan with cooking spray.
In a small bowl, combine the flour, baking powder, baking soda, and salt; mix well and set aside.
In a large bowl, cream the butter and sugar. Add the egg, peanut butter, sour cream, and banana; mix well. Add the flour mixture; mix well, then spread into the cake pan.
Bake for 30 to 35 minutes, or until a wooden toothpick inserted in the center comes out clean. Let cool in the pan for 10 minutes, then remove from the pan to cool completely before cutting into wedges.

Notes

Even though peanut butter is a good source of protein, it's high in fat, and should be eaten in moderation… so save this one for special occasions.

Bananas come in different sizes. How much, exactly? 1/2 cup? 3/4 cup?

Bananas do come in different sizes and if Test Kitchen suggests 1 large banana then the recipe must definitely need that amount of banana for moistness and flavor. If Test KItchen suggests 1 banana without stating size, then it doesn't matter the size because the recipe will work no matter if alittle extra banana is used or not. Mashed bananas in our baked goods are used for sweetness, moistness, and flavor. In general, 1 small banana equals about 1/3 cup, 1 medium banana equals about 1/2 cup, and 1 large banana equals about 3/4 cup mashed. Hope this helps. :)

I love the idea of banana and peanut butter in a cake! You can satisfy your sweet craving and still feel like you are eating healthily. I do have a question, though. Can you substitute whole wheat flour for the white flour? I am trying to cut out as much flour, sugar and carbs as possible, but I would love to have a cake recipe that is healthier than the ones I usually make. Also, can you substiture honey for the sugar or would that really change the flavor?

Hello! We recommend using half whole wheat flour and half white flour, instead of all whole wheat flour. Also, honey would definitely change the flavor of this cake. We suggest stevia as a sugar alternative. Enjoy!
