Why you’ll love this recipe & key ingredients

Oat flour is one of my favorite gluten free flours to bake with because it’s so cheap and creates perfectly fluffy desserts.

This gluten free oat flour cake has a delicious banana flavor, plenty of chocolate chips and is topped with a simple cream cheese frosting. It’s the perfect healthy dessert when you don’t want a sugar overload but still want something sweet and indulgent.

It’s a cross between banana bread and banana cake but with the additional of chocolate chips for extra flavor.

Oats, and therefore oat flour, are naturally gluten free. However, they can be easily contaminated during processing, so make sure you use a certified gluten free oat flour if baking for someone with celiac disease.

To make oat flour cake, you will need oat flour, of course, plus eggs, banana, honey, sugar, oil or butter and some baking powder to help the cake rise. If you love this recipe, try my banana bread donuts or oat flour brownies next.

How to make oat flour cake

PUREE BANANA. Add your ripe bananas to a blender and blend until smooth. You can mash them, but I find the texture of the cake is best with pureed banana instead of mashed.

MIX WET. Measure out 1 cup and add to a mixing bowl with all wet ingredients. Mix with an electric mixer until well combined.

MIX DRY. Add in the dry ingredients, aside from the chocolate chips, making sure to spoon and level the flour. Mix until smooth, then fold in the chocolate chips.

BAKE. Transfer to your prepared pan and bake for 22-30 minutes or until a toothpick comes out clean. Remove from the oven and let cool in the pan for 15 minutes, then lift out onto a wire rack to finish cooling.

MAKE FROSTING. Meanwhile, beat together the softened butter and cream cheese for 2-3 minutes. Add in the powdered sugar followed by the vanilla until smooth and creamy.

If it’s too thick, add a splash of milk, if you want it thicker, add more sugar.

SERVE. Once the cake has cooled, add the frosting on top and enjoy!

How to store and freeze

Because this oat flour cake is so moist from the banana, eggs and butter, it stores really well without drying out!

Once it’s cooled and frosted, I suggest slicing it into squares and storing either in a container with a lid, or on a plate with foil. Because the frosting has cream cheese, I suggest storing in the fridge for up to 5 days.

If you want to prep this cake in advance, you can bake it, let it cool completely, then wrap tightly in plastic wrap and freeze until you’re ready to frost and serve.

Cake pan sizes

I baked this cake in an 8×8 square pan, which I recommend. This classifies it as a “snack cake” and makes it perfect for small get togethers or parties.

You can instead bake it in an 8 inch round cake pan, or double the recipe to make a traditional layer cake.

This recipe will also work as oat flour cupcakes. Follow all of the same instructions, but bake in a lined cupcake tray for about 18 minutes or until a toothpick comes out clean.

Frequently asked questions

Can I replace all purpose flour with oat flour?

Generally, I don’t recommend swapping out all purpose flour for any kind of gluten free flour. Instead, it’s best to follow a recipe that already calls for oat flour or whatever gluten free flour you want to bake with.

Substituting oat flour for cake flour or regular all purpose flour can really change both the taste and texture in a recipe, especially a cake.

Is oat flour good for cakes?

In most of my gluten free cake recipes, I stick with GF all purpose baking flour and/or almond flour. However, oat flour is good for cakes because it’s affordable and creates deliciously fluffy cakes.

Especially when combined with a bit of starch it creates a traditional cake like texture.

Can I use different sugar?

This cake uses a mix of honey, granulated sugar plus the ripe bananas to sweeten. Instead of honey, you can swap for maple syrup.

I used white sugar, but you can use coconut sugar for a refined sugar free option. Keep in mind the color of the cake will be a bit darker than pictured!
