  • 1/2 tsp ground nutmeg
  • 3 medium ripe bananas, mashed, approx. 1 cup
  • 2 large eggs, at room temperature
  • 1/2 cup whole milk
  • 1/4 cup extra virgin olive oil
  • 1 tsp vanilla extract

Cream Cheese Frosting

  • 4.4 oz. full-fat block cream cheese,

    at room temperature


  • 60 g unsalted butter,

    softened at room temperature


  • 1 3/4 cups powdered sugar
  • 1/4 tsp ground cinnamon

Instructions

Banana Cake

  • Preheat Oven: Preheat the oven to 350ºF (180ºC). Lightly grease a 13x9-inch baking pan with butter or non-stick spray. (Optional: For easier removal, line the base with parchment paper.) Set aside.
  • Combine Dry Ingredients: In a large mixing bowl, add the cake mix, baking soda, cinnamon and nutmeg. Whisk until well combined.

  • Mix Ingredients: Add the mashed bananas, eggs, milk, oil and vanilla. With electric beaters, beat on low-medium speed for 40 seconds until well combined, ensuring not to over-mix.
  • Transfer To Pan: Pour the batter into the prepared cake pan.

  • Bake Cake: Bake for 28-30 minutes or until a toothpick inserted into the center comes out clean or with a few moist crumbs.

  • Cool: Let the cake cool in the tin for 15 minutes. Then, gently remove it from the tin and transfer it to a wire rack to cool completely before adding the frosting.

Cream Cheese Frosting

  • Mixing: In a large mixing bowl using electric beaters, beat the softened cream cheese and butter for 1 minute on medium speed. Scrape down the sides.
  • Add Sugar and Cinnamon: Sift in the powdered sugar and ground cinnamon together and beat for 40 seconds on medium-high speed until well combined and whipped.
  • Frost Cake: Spread frosting evenly over the cooled banana cake.
Cut the cake into slices, serve and enjoy!
