A quick and easy microwave mug cake that is kid-safe, uses simple pantry ingredients, and delivers a warm, chocolatey treat in just minutes.

Ingredients

Scale
  • 4 tablespoons all-purpose flour (about 30 grams / 1/4 cup)
  • 4 tablespoons sugar (50 grams / about 1/4 cup; white or brown sugar works)
  • 2 tablespoons unsweetened cocoa powder (15 grams)
  • 1/4 teaspoon baking powder
  • A pinch of salt
  • 3 tablespoons milk (45 ml / 2 tablespoons + 1 teaspoon; whole or plant-based)
  • 2 tablespoons vegetable oil (30 ml / 2 tablespoons; can substitute melted butter)
  • 1/4 teaspoon vanilla extract
  • Optional add-ins: 1 tablespoon chocolate chips, chopped nuts, or a spoonful of peanut butter

Instructions

  1. Combine dry ingredients: In a microwave-safe mug, add flour, sugar, cocoa powder, baking powder, and salt. Stir well with a spoon or small whisk to break up any lumps (about 1-2 minutes).
  2. Add wet ingredients: Pour in milk, vegetable oil, and vanilla extract. Stir gently but thoroughly until the batter is smooth and no dry spots remain (about 1 minute).
  3. Mix in optional add-ins: Fold in chocolate chips, nuts, or peanut butter if using (about 30 seconds).
  4. Microwave cooking: Place the mug in the microwave and cook on high for 70-90 seconds. Start with 70 seconds and add 10 seconds if needed. The cake should rise and look set but still moist on top (max 1.5 minutes).
  5. Cool slightly and enjoy: Let the mug cake cool for about 1 minute before eating to help it firm up and avoid burning your tongue.

Notes

Use fresh baking powder for best rise. Avoid overmixing to prevent toughness. Microwave power varies; start with 70 seconds and add time in 10-second increments if needed. Let cool slightly before eating. For gluten-free, substitute all-purpose flour with almond or oat flour. For vegan, use plant-based milk and coconut oil instead of vegetable oil.
