How to Make This 3-Ingredient Chocolate Oatmeal Chocolate Cake Recipe

Before you begin, grease a 7-inch (18-centimeter) round cake pan with butter or oil. Then, line the bottom with parchment paper, and grease it as well.

Melt the chocolate: Bring the coconut milk to a simmer in a small saucepan on the stove. Then, pour the liquid over the chopped chocolate in a heatproof bowl. Let the mixture sit to melt the chocolate, and stir to combine.
Add the oats: Stir the oats into the chocolate mixture, coating them completely.
Chill: Pour the cake batter into the prepared pan, and let it cool to room temperature. Transfer the cake to the fridge, and let it chill for at least 4 hours or until it’s fully set.

Frequently Asked Questions

What does oatmeal do for cake?

Oatmeal acts as a binder, holding all the ingredients together. It also helps create a thick, moist texture rather than the light, fluffy texture you find in cakes made with flour. As a result, this cocoa oatmeal cake is rich and fudgy, similar to my brownies recipe.

Are oatmeal cakes healthy?

Unlike traditional cakes, this oatmeal chocolate cake recipe is free from added sugar and contains far less fat and carbs. In addition, it provides a good source of complex carbs, fiber, and antioxidants, which makes it a healthy recipe in my book!

Can I add frosting?

Sure! Once the cake has cooled and set, feel free to top it with your favorite homemade or store-bought frosting just before serving.
