Ingredients & Substitutions

Oats: Look for old-fashioned oats, also known as rolled oats. They will soak in boiling water before being mixed in with the other ingredients. Letting them soften up adds even more moisture to the cake. I do not recommend quick oats.

Butter: For both the cake and the frosting, use unsalted butter. This gives you, the baker, more control over the amount of salt added to the recipe. If using salted butter, you may want to lessen the amount of salt in the cake.

Sugar: You will need both granulated sugar and light brown sugar for the cake, with more brown sugar needed for the frosting.

Coconut Flakes: Sweetened coconut flakes are added to the frosting for a tropical flair!

Walnuts: For a nutty crunch, I added chopped walnuts to the frosting.

Can I Make The Cake Ahead Of Time?

Yes, you can get the oatmeal cake baked up to a couple of days in advance. Once you have baked the cake, let it cool to room temperature. Then, store it, covered, at room temperature for up to 2 days. Frost the cake when ready to serve. Or, freeze the baked cake (unfrosted) for up to 2-3 months. When ready to frost and serve the cake, let it thaw in the refrigerator overnight.
