Oat Flour Cake (Easy and Delicious)

Last Updated: January 2, 2026

This chocolate oat flour cake recipe is one of my favorite gluten-free desserts. Give this moist, fudgy cake a try if you’re looking for nutritious treats, like these chocolate oat clusters, which are another delicious option.

Ingredients and Substitutions

Oat flour is an excellent option if you’re looking for gluten-free flour alternatives. Just be sure to choose oat flour that is specifically labeled gluten free to avoid cross contamination with gluten, if that is a requirement for you. You can either use store-bought oat flour or make your own at home by blending rolled oats in a food processor or blender until a flour-like consistency is achieved.

Almond butter gives this cake a moist, rich texture. It also acts as a binder, so there’s no need for eggs in this recipe. You can substitute any other type of nut butter or seed butter you prefer, just be sure to use a creamy variety.

When I originally developed this recipe, I did not include the cocoa powder or the chopped dark chocolate, and I used 1 teaspoon of cinnamon instead. Lately I prefer the chocolate version, but both flavors are delicious.

How to Make Oat Flour Cake

Watch this short video to see the steps:

Start by preheating the oven to 350 degrees Fahrenheit. Next you’ll add the creamy almond butter, maple syrup, unsweetened milk of choice, pure vanilla extract, cocoa powder, and salt to a mixing bowl, then use a whisk to mix well. Add the oat flour and baking powder to a separate bowl, then mix well. Be sure to spoon the oat flour into the measuring cups—don’t scoop.

Transfer the oat flour and baking powder mixture into the bowl with the other ingredients, then whisk to combine. Add the chopped dark chocolate, then mix to combine.

Transfer the batter to a 9-inch baking pan lined with parchment paper.

Bake for 33 minutes or until the top looks set and the center doesn’t jiggle. Be sure to let the cake cool to room temperature before removing from the pan and serving.

Notes

  • Store in an airtight container in the fridge for up to five days or in the freezer for up to three months. Thaw in the fridge or at room temperature before serving. I like to slice the cake into portions before freezing so I can easily thaw the exact amount I want.

    Fantastic! I used ChocZero maple syrup and dark chocolate chips to keep this sugar-free, and raw almond butter. I used an 8″ square pan and baked for the 33 minutes. It came out moist and flavorful, with a deep, dark chocolate flavor. I dusted the top with a mixture of cocoa powder and a monkfruit/allulose powdered sugar. I’ll definitely be making this again; thanks for the great recipe!
