How To Make best banana cake

  • Step 1
    Preheat oven to 350 degrees F. Spray a 9x13-inch metal baking pan with baking spray.
  • Step 2
    Mash the bananas and lemon juice in a small bowl. Whisk the flour, baking soda, baking powder, and salt in a medium bowl.
  • Step 3
    Using a stand mixer with the paddle attachment on medium speed, beat the butter, sugar, and brown sugar until well mixed. Turn the mixer to low, add the eggs, one at a time, beating just until combined. Add the vanilla extract and beat just until combined.
  • Step 4
    With the mixer on low, add the dry ingredients in several increments, alternating with the buttermilk. Scrape down the bowl and beater when needed. Mix just until combined. Remove the bowl from the mixer and stir in the banana mixture.
  • Step 5
    Pour the batter into the prepared baking pan. Bake for 40-50 minutes or until a toothpick inserted in the center comes out clean or with a few moist crumbs.
  • Step 6
    Put the cake in the freezer for 45-60 minutes.
  • Step 7
    Using a stand mixer (with paddle attachment) or a hand mixer on high speed, beat the cream cheese and butter until smooth and creamy.
  • Step 8
    Turn the mixer to medium and add the vanilla extract and salt. Turn the mixer to low and gradually add the powdered sugar, beating until well combined. Frost the cake. Store it in the fridge until ready to serve.
