This recipe is absolutely one of my favorite desserts. This recipe is moist and the banana and peanut butter are surprisingly not overpowering. The inspiration came from a fabulous muffin I tasted in Austin. I then embarked on a journey to get ideas to work into my own from the web. I started with a recipe I saw on kevinandamanda.com and made my changes. Like all my recipes, tweak the ingredients for your taste buds.
1 box of yellow cake mix
1 package of banana cream pudding
1 c. sour cream
1 c. vegetable oil
1/2 c. milk
1 tsp vanilla
1 large banana
1/2 c peanut butter
1 8oz package of softened cream cheese
1 cup powder sugar (add more or less to your taste)
1 stick of softened unsalted butter
1/4 c of milk (add more for creamier frosting)
In a separate bowl combine frosting ingredients and stir until smooth and creamy. I like a creamier frosting so I tend to add a little more milk. I also don't use quite as much powdered sugar. Frost the cupcakes when they are cooled. Serve and enjoy!
