- Egg
- Sour cream
- Vanilla extract
- Powdered sugar

- Honey
Equipment:
- 8x8 inch pan
- Mixing bowls
- Whisk
- Spatula

- Measuring cups or scale

- Parchment paper
Recipe Notes:
This recipe has the best banana flavor and is moistened with a bit of sour cream. You might know from my Banana Baked Donuts that I love pairing peanut butter and honey with bananas, so I added a PB honey flavored buttercream to this cake!
The first thing you'll want to do is take your 2 brown bananas and mash them in a bowl with a fork (picture #1 below). Whisk together the dry ingredients and set both of those bowls aside while you cream together the softened butter & sugars. Mix in the egg, vanilla extract, sour cream, followed by the mashed bananas. Finally, stir in the dry ingredients and pour the batter into a square pan. I recommend spraying the pan with oil and then lining sheets of parchment paper across it so that it's easy to pull out of the pan (picture #4 below).
Bake the cake at 350°F until the top is golden and a toothpick comes out of the center clean. While the cake is in the oven, whip together the butter, peanut butter, honey and powdered sugar. You'll want to wait for the cake to cool before frosting it, but this way it'll be ready to go! After frosting it, I sprinkled a few honey peanuts on top and cut it into 16 squares. If you want bigger slices, feel free to slice it up as 3x3!
Questions & Storage:
It's made in an 8x8 inch pan that cuts into 16 little square slices - perfect for snacking! It also has delicious frosting on top! Or you can leave the frosting off and have even more surface area of the soft, moist top (AKA my favorite part of banana bread!) It also takes less time to bake than a loaf!
Frosted cake should be stored in the refrigerator for up to 1 week. If it's unfrosted, it can be stored at room temperature.
It's delicious unfrosted, or I'd recommend trying a cream cheese frosting! Try cutting the recipe in half from my Cowboy Cookie Cake. If you're feeling chocolatey, try the whipped chocolate ganache from my Banoffee Cupcakes!
