Ingredients You’ll Need

Here are some of the ingredients that make this delicious banana cake really shine!

  • Gluten-Free 1:1 Baking Flour: I like to use a high quality gluten-free measure-for-measure flour blend like King Arthur Flour in my baked goods. It works best to use a blend that contains xanthan gum in this recipe.
  • Sour Cream/Oil: Adds richness and tenderness to the gluten free banana cake without weighing down the crumb. It truly makes for the best gluten-free cake!
  • Lemon Juice: Lemon juice helps to tenderize the crumb. It’s the secret ingredient in my gluten-free blueberry muffins as well.
  • Baking Powder: I use a good amount in this gluten free banana cake recipe for the perfect rise.

How to Make Gluten-Free Banana Cake

Make the Gluten-Free Banana Cake

Banana cake wet and dry ingredients in separate bowls
  • Preheat the oven to 350°F and grease a 9×13 inch baking pan. 
  • In a large bowl, whisk together the dry ingredients, including gluten-free flour, baking powder, baking soda, cinnamon and salt.
  • In a separate large mixing bowl, mash the bananas. Add the wet ingredients, including sour cream, milk, vanilla extract, and lemon juice.

  • In the bowl of a stand mixer (or using a large bowl and electric hand mixer), add the white sugar, brown sugar and eggs. Whip on medium-high speed for 3 minutes, until light and fluffy. With the mixer running on low, slowly drizzle in the oil. (You want to do this slowly so you don’t loose the air that you’ve mixed in.)
  • With the mixer on low, add ½ of the dry ingredients. Mix until incorporated. Add ½ the banana mixture and mix until combined. Add the remaining 1/2 of the dry ingredients and continue to mix.
  • Mix in the rest of the banana mixture. Mix the batter until well combined, then scrape down the sides and bottom of the bowl and mix again. (You want to add the dry ingredients alternately with liquid ingredients so the flour absorbs into the batter.)

  • Pour the gluten free banana cake batter into the prepared pan. Bake for 35-40 minutes until golden and a toothpick inserted into the center of the cake comes out clean.
  • Remove the cake from the oven and set on a wire rack. Let the cake cool completely. After about 45 minutes, I usually place it in the refrigerator to speed things up.

Make the Cream Cheese Frosting

  • Using a hand or stand mixer, beat together the butter and cream cheese until combined. Add the powdered sugar and vanilla.
  • Beat on low then switch to high for about three minutes or until light and creamy. Scrape down the sides and bottom of the bowl then mix for another 30 seconds or so.
  • Smooth the frosting over the cooled banana cake. Slice and enjoy this moist gluten free banana cake!

Banana Cake FAQs

What is the difference between banana cake and banana bread?

Banana bread is more firm and dense than banana cake. Banana bread is served plain and is usually less sweet, while banana cake is topped with frosting.

Why is my banana cake not moist?

If you use too much gluten-free flour or low-quality gluten-free flour, your banana cake may end up dry. I use a combination of sour cream and oil to achieve a moist, tender crumb in this delicious cake.

How do you make gluten free cakes rise?

This recipe includes lemon juice, which reacts with baking soda to create extra rise and produce a more tender cake. Adding an extra egg can also help a gluten-free cake rise.

Expert Tips and Tricks

  • You could turn this recipe into banana cupcakes by scooping the batter into cupcake liners and reducing the baking time.
  • You could also make this into a sheet cake by pouring the batter into a sheet pan and reducing the baking time.
  • I love pairing this gluten-free banana cake with cream cheese frosting, but you could also use vanilla frosting or even peanut butter frosting instead!
  • Are you a chocolate lover? Consider adding chocolate chips to the batter to add an extra dose of chocolatey goodness!

      So I think I understated this recipe in my first review…this is the best gluten free cake I have baked in my 12 years of gluten free baking. Still amazing two days after baking. Thank you again.

    We loved this recipe! Pre-Celiac days, my grandmas banana cake was a staple in my life for most celebrations. 8″ layers with cream cheese frosting. I’ve searched for two years for a recipe just like this one and wow, you nailed it! I baked this in a 9×13 and followed the recipe as written (I used a scale to measure ingredients). I just enjoyed a slice with my morning coffee and I can attest it’s tasty the day after, which I’ve found isn’t always the case with gf baked goods. I am already planning on attempting it as a layer cake for my daughters First Communion in May. I’ll be adding some chopped candied pecans on the top just like Grandma!
