When you have a sudden dessert craving, but you don’t want to spend hours in the kitchen, a mug cake is the perfect solution. With just a few ingredients and a microwave, you can whip up delicious cakes in minutes. Today, we’ll guide you through two incredibly simple and delightful 3-ingredient mug cake recipes.

Chocolate Mug Cake


  • Cocoa powder
  • Egg
  • Maple Syrup


  • In a microwave-safe mug, whisk together the egg, cocoa powder, and maple syrup until smooth.
  • Microwave for 1 minute and 20 seconds. If the middle appears raw, microwave for an additional 10 to 20 seconds.

Though the ingredients may hint at a sweet chocolate omelet, the result is far from it. If you’ve ever indulged in a molten lava cake at a fancy diner, this mug cake closely mimics that but without the heavy cream.

Peanut Butter Mug Cake

  • In a small bowl or directly in your microwave-safe mug, beat the egg and peanut butter together.
  • Whisk in the cocoa powder until the batter is smooth.
