Banana Cake with Vanilla Bean Frosting

Banana Cake with Vanilla Bean Frosting – light and fluffy banana cake with a delicious vanilla bean frosting! The perfect afternoon snack! 

Remember how a few short days ago I told you that we go through 27 bunches of bananas a week?

Well, that very day my 2 year old, who has been known to kill 4 bananas in the time it takes me to shower, decided he doesn’t like bananas anymore.

Coincidentally, that was also the day I went to Costco and bought a huge bag.

I can’t even remember the last time I had bananas so ripe that I was forced to bake with them! I took full advantage of the situation and made this fantastic little banana snack cake.

Ingredients

• 4 tablespoons unsalted butter
• ⅔ cup sugar
• ½ cup sour cream – you can substitute plain Greek yogurt
• ¾ cup mashed very ripe banana – about 2 bananas
• 1 egg
• 1 teaspoon vanilla
• 1 cup flour
• ¼ teaspoon salt
• ½ teaspoon baking soda
• 1 ¼ cups powdered sugar
• ½ vanilla bean, seeds scraped from the bean, or ½ teaspoon vanilla bean paste
• ¼ cup heavy cream or milk

Instructions

1. Preheat oven to 375F. Line a 9×9 square pan with parchment.
2. Cream together butter and sugar until light in color and fluffy. Add in sour cream, mashed banana, egg, and vanilla. Beat until combined.
3. In a separate bowl, sift together flour, salt, and baking soda.
4. Add dry ingredients to wet ingredients and beat until just combined.
5. Pour mixture into the prepared pan. Bake in preheated oven for 22-26 minutes, or until a toothpick inserted into the center comes out clean.
6. Let cool completely before frosting.
7. To make the frosting, beat butter and powdered sugar together; add vanilla bean seeds and salt. Slowly add heavy cream, one tablespoon at a time, until the frosting reaches the desired consistency.

How Long Is Banana Cake Good For?

This banana cake will be good at room temperature for about 2 days. Make sure to cover it tightly to keep it as fresh as possible.

You can stretch the time it’s good for by putting it in the fridge for up to 4 days. The fridge will dry it out a little so make sure it’s in an airtight containers, like these super airtight glass containers.

If you refrigerate it, I would let it sit at room temperature for 20 – 30 minutes before serving just to get the chill off.
