Instructions
Banana Cake
- Preheat the oven to 350°F. Spray an 8x8 inch pan with oil and line parchment paper across so that it extends up the sides.
- In a small bowl, mash the bananas with a fork and measure them.
- In another small bowl, whisk together the flour, baking soda, salt and cinnamon.
- In a large bowl, cream together the butter and brown sugar until light and fluffy. Mix in the egg, vanilla extract and sour cream (one at a time). Then, stir in the mashed bananas. Finally, mix in the dry ingredients just until the flour streaks are gone. Scrape the sides of the bowl as needed.
- Pour batter into the parchment-lined pan and bake until the top is golden and a toothpick comes out clean (22-28 minutes). Let the cake cool completely before frosting.
Peanut Butter Honey Frosting
- Mix together the butter, peanut butter, honey and powdered sugar until smooth. Add a bit of heavy whipping cream if it's too thick or dry.
- Spread frosting over the cooled cake, slice into 9 or 16 equal squares and enjoy!
