Equipment

  • Microwave-safe mug (wide, 12–14 oz capacity)
  • Spoon or fork for mixing
  • Microwave

Ingredients
  

  • 4 tbsp all-purpose flour
  • 2 tbsp unsweetened cocoa powder
  • 2 tbsp sugar
  • ¼ tsp baking powder
  • Pinch of salt
  • 3 tbsp milk (dairy or non-dairy)
  • 2 tbsp vegetable oil or melted butter
  • ¼ tsp vanilla extract
  • Optional: chocolate chips, whipped cream, berries

Instructions
 

  • Mix dry ingredients: In a microwave-safe mug, stir together flour, cocoa powder, sugar, baking powder, and salt.
  • Add wet ingredients: Pour in milk, oil (or butter), and vanilla. Mix until smooth and lump-free.
  • Optional add-ins: Stir in chocolate chips or a spoonful of Nutella for extra indulgence.
  • Microwave: Cook on high for 60–90 seconds. The cake should rise and look set but slightly moist on top.
  • Cool slightly: Let rest for 1–2 minutes before eating—it will be hot.
  • Top & serve: Add whipped cream, ice cream, or berries if desired.
  • Expert Tip: Use a wide mug to prevent overflow and ensure even cooking.

Notes

  • Cooking times vary by microwave wattage—check early to avoid dryness.
  • Whole wheat flour or sugar substitutes can lighten the recipe.
  • Vegan option: use plant-based milk and oil instead of butter.
  • Best enjoyed fresh; reheating may dry out texture.
  • Fun to customize—try peanut butter, caramel drizzle, or mint extract.
