What is a mug cake?

Just as the name suggests, this easy dessert is quite literally a cake in a mug. Instead of baking in the oven, it’s made in the microwave in just two minutes. Mug cakes contain typical cake ingredients, like flour, milk, butter, sugar, and leavener. However, you’ll notice that no eggs are needed.

This particular recipe is a healthy, plant-based twist on traditional cake. Therefore, we’ll use whole food alternatives such as oat flour, almond milk, almond butter, and maple syrup. It’s truly a guilt-free indulgence since it’s made with nutritious ingredients.

Ingredients needed

  • Oat flour: Oat flour is a fiber-packed alternative to plain flour. It’s naturally gluten-free and packed with minerals. You can make your own oat flour by blending rolled oats in a blender or a food processor. If you choose to do this, be sure it is blended into a very fine flour. It should be as close to regular flour as possible.
  • Pumpkin: Use canned pumpkin purée, not pumpkin pie filling. If you cannot find pumpkin purée at a grocery store, you can easily make your own with fresh pumpkin at home.
  • Almond butter: Creamy almond butter is my favorite for this recipe. However, you can also try peanut butter or cashew butter.
  • Maple syrup: This mug cake contains no refined sugar. Instead, it is sweetened with real maple syrup.
  • Almond milk: Use almond milk or another plant-based milk, like oat milk or coconut milk.
  • Pumpkin pie spice: This blend of warm spices includes cinnamon, nutmeg, cloves, allspice, and ginger. You can buy it at a grocery store or make your own at home.
  • Cinnamon: Although pumpkin pie spice already contains a bit of cinnamon, I love adding extra for a rich cinnamon flavor.
  • Vanilla: Vanilla extract makes nearly every dessert taste more delicious. Don’t skip it!
  • Baking powder: This ingredient is a leavener which helps the mug cake rise in the microwave.
  • Salt: Add a pinch of salt to enhance the other ingredients.

What are the best mug cake toppings?
