Ingredients

  • 1 tablespoon butter
  • 2 tablespoons brown sugar
  • 1/2 teaspoon vanilla extract
  • 1 large egg
  • 1/2 cup quick oats
  • 1/2 teaspoon baking powder
  • 1/4 teaspoon cinnamon
  • pinch nutmeg and salt
  • 1/4 cup milk

Instructions

  • Grab a 12 oz mug and generously spray the inside with baking spray to prevent sticking.
  • Place butter in the mug and microwave it for about 20-30 seconds or until it’s fully melted.
  • Add the brown sugar and vanilla to the mug with the melted butter. Whisk them together until well combined.
  • Crack an egg into the mug, then add the oats, baking powder, cinnamon, nutmeg, and a pinch of salt. Mix everything together until it’s nicely blended.
  • Stir in the milk until everything is smoothly incorporated.
  • Put the mug in the microwave and heat for 30 seconds. Then pause and stir the mixture to help it cook evenly.
  • Microwave for an additional 1 minute. Check if the cake is done—it should be set and slightly springy to the touch.
  • Let it cool for a minute or two before enjoying your freshly made oatmeal mug cake!

Notes

  • Whisk Thoroughly: Whisk the ingredients vigorously after adding each to break up clumps and incorporate air, making the cake lighter and fluffier.
  • Adjust Microwave Time: Microwaves vary in power, so start with the shorter cooking time and add more in short bursts if needed. This prevents overcooking, which can make the cake rubbery.
  • Add Toppings: Enhance your mug cake with toppings like a dollop of yogurt, a sprinkle of granola, fresh fruit, or a drizzle of honey or maple syrup right before serving for added flavor and texture.
  • Use a Tall Mug: Choose a tall mug to allow the cake room to rise without spilling over as it cooks.
