Banana Blueberry Oat Cake

Delicious slice of cake

This was the first time I made this cake and it is wonderfully delicious. After the first bite I wanted 4 more slices. I decided to restrain myself and enjoy the one slice I was eating. Gathering the supplies, prepping the pans and preparing the cake went smoothly.

  • Ingredients: 1 Cup unsalted butter, softened
  • 2 1/2 Cups of granulated sugar
  • 4 large eggs at room temperature
  • 1 Tablespoon vanilla extract
  • 2 3/4 Cups of all-purpose flour
  • 3/4 Cup of oat flour
  • 1/3 Cup oats
  • 2 teaspoons baking powder
  • 2 teaspoons baking soda
  • 1 teaspoon salt
  • 1/2 teaspoon cinnamon
  • 1/4 teaspoon ground ginger
  • 2 Cups mashed ripe bananas
  • 1 Cup buttermilk, room temperature
  • 1 1/2 Cups fresh blueberries

Tricks of the trade: Use eggs at room temperature. Make your own oat flour. I thought this would be difficult but it was easy as pie. I placed old-fashioned oats in a blender and pulsed a few times and presto my oats were oat flour. I used 3 bananas because that is what I had. Place blueberries in the freezer while preparing the batter. When it is time to use the blueberries, they will be firm and mix well.

Cake pan with parchment paper.

Preheat oven to 350°. Grease and flour pans and then line with parchment paper. I’ve been trying this method lately but I am still undecided if this is the best way to prepare a pan. My next cake may be just with butter and flour.

In a mixer, add butter and sugar and beat at medium speed, 3 – 4 minutes. Add eggs 1 at a time, beating well after each addition. Beat in vanilla.

In a large bowl, whisk together, flour, oat flour, oats, baking powder, baking soda, salt, cinnamon and ginger. In another bowl, mix mashed banana and buttermilk.

Add flour mixture to buttermilk alternating the ingredients. Begin and end with flour mixture. Toss blueberries with 1 1/2 Tablespoons flour and add to mixture. Put mixture into 2 circular pans and bake for 50 – 60 minutes at 350°.

When toothpick comes out clean, remove pans from oven and let them cool for 10 minutes. Remove cake from pans and allow the cake to cool completely.

To make frosting, mix 1/4 Cup butter, 1 pound powdered sugar, 1/2 whole buttermilk, and 1 teaspoon vanilla extract. Mix all ingredients until smooth. Place a small layer of frosting between layers. Then place a layer on top of the other layer. Frost the cake beginning with the top layer. When the frosting is finished, add blueberries to the top.

Enjoy the cake and let me know how everything tastes.
