Expert Tips for Making Oat Mug Cakes

  • Oat Flour at Home: If you’re out of oat flour don’t fret! Oat flour is quick and easy to make, and all you need is oats. Add your favorite brand of rolled oats in your blender and blend until it comes to a flour consistency. The best part? It’s cheaper to make at home.
  • Gluten Free: Use oat flour instead of all purpose flour for gluten-free desserts. Oat flour isn’t just gluten free, it’s sweeter than all-purpose flour, and creates a chewier texture.
  • Butter vs. Oil: If your cake is coming out rubbery, substitute the oil with melted butter instead for a fluffy cake.
