Why You Will Love This
- Easy to make- This recipe is incredibly easy to make. This banana cake is full flavor and made an 8X8 pan.
- Soft banana cake- This cake is super soft because it has 2 ripe bananas and sour cream.
- Peanut butter frosting- Peanut butter frosting is my FAVORITE type of frosting. It isn’t too sweet.
Ingredients
Here are some notes about the ingredients used.
- Room temperature dairy ingredients- Pull these out 2 hours before baking. This is a MUST.
- Baking soda + baking powder- This uses both rising agents to get a better rise out of the cake.
- Ripe bananas- The best type of bananas to use are fairly brown spotted bananas.
- Sour cream- Use full fat sour cream.
- Slightly cold butter- Leave the butter out for 30 minutes. The butter needs to be cold enough to be firm enough for frosting. Also, not so cold you can’t beat it until smooth.
- Peanut butter- I used Jif creamy peanut butter.
Step By Step Instructions
Here are the steps to make the cake and the frosting.
STEP 1: First, spray an 8X8 pan with baking non-stick spray. Make sure to line the bottom and 2 sides of the pan with parchment paper.
STEP 2: Next, mix the dry ingredients. Mix the flour, baking soda, baking powder, salt, and cinnamon.
STEP 3: Then, beat the butter and sugars. Beat these until very light and fluffy. Next, add in the vanilla, sour cream, and mashed bananas.
STEP 4: Add in the eggs. Once combined, add in the dry ingredients. Next, mix until combined. Don’t over mix.
STEP 5: Now, pour cake batter into the pan. Bake for 25-30 minutes. Next, let the cake cool completely before decorating.
STEP 6: Then, beat slightly cold butter on high. Once creamy, add in the peanut butter. Scrape the bowl several times.
STEP 7: Next, add in the powdered sugar. Then, add in the heavy cream and vanilla. It should be very creamy and smooth.
STEP 8: Now, decorate the cake. Then, top with fun toppings!
Baking Tips
First, to get the best rise out of the cake, make sure to pull the cold ingredients out 2 hours before baking.
If you are making the frosting and it is too gritty, sift the powdered sugar.
If it is too thick and starts to separate, add a splash more heavy cream. Then, beat the frosting until smooth.
This cake tastes so great with just the frosting and cake. If you would like to spruce it up like mine, add some toppings!
I used sliced bananas, chopped pecans, and halved Reece’s peanut butter cups.
FAQ
