The Best MOIST Banana Cake with Oil

This Banana Cake recipe is made with oil (no butter needed!) and a great way to use those spotted bananas! With these easy step-by-step instructions, you'll bake an incredibly moist and indulgently sweet banana cake from scratch. Finished with a luscious layer of whipped cream cheese frosting, ( a reader favorite!) this cake is one you'll come back to over and over!

Ingredients

  • 1 cup (225 g) banana , ripe, mashed, About 2 medium-large or 3 small bananas
  • 3 (3) large eggs
  • 1 cup (218 g) vegetable oil
  • 2 tsp (2 tsp) vanilla extract
  • 1 1/2 cups (300 g) granulated sugar
  • 2 cups (240 g) all purpose flour
  • 1 tsp (1 tsp) baking powder
  • 1/2 tsp (0.5 tsp) baking soda
  • 1/2 tsp (0.5 tsp) kosher salt
  • 1 batch (1 batch) Cream Cheese Frosting

Instructions
 

  • Preheat the oven to 350 F and generously grease a 9x13” pan with baking spray. You can make this recipe by hand or by using a hand or stand mixer on medium speed.
  • In a large bowl mash the 1 cup bananas. It's ok if there are little lumps. Add the 3 eggs, 1 cup vegetable oil, and 2 teaspoons vanilla extract and stir to combine. Add the 1 1/2 cups of sugar to combine.
  • In another bowl or over a large piece of parchment paper combine the 2 cups of flour, 1 teaspoon baking powder, 1/2 tsp baking soda and 1/2 tsp salt. Add the mixture to the bowl and mix lightly until combined.
  • Pour the batter into the pan and bake for 30-35 minutes. The cake is done when the edges start to pull away from the sides and the top feels firm when touched.
  • Allow cake to cool at least 10 minutes in the pan and then invert into a wired rack to cool completely before frosting.
  • Frost with my homemade whipped cream cheese frosting and enjoy!

Notes

You can also frost this with classic cream cheese frosting!
