What you will need

This recipe uses 6 simple ingredients that you can find at any grocery store:

  • 3 tablespoons all-purpose flour
  • 2 tablespoons sugar
  • 1 teaspoon matcha powder
  • 1 large egg
  • 3 tablespoons milk
  • 2 tablespoons butter melted

Step by step instructions

Step 1: Combine Dry Ingredients

In a large microwave-safe mug, whisk together flour, sugar, and matcha powder until the matcha is evenly distributed throughout and there are no green clumps remaining.

Step 2: Add Wet Ingredients

Add the egg, milk, and melted butter to the mug. Stir vigorously with a fork until a smooth batter forms and no flour streaks remain on the sides of the mug.

Step 3: Microwave the Cake

Microwave on high power for 60 to 90 seconds, checking at 60 seconds. The cake should be just set in the center with moist edges and slightly pulling from the sides of the mug.

Step 4: Rest and Garnish

Let the cake cool for one minute, then dust the top lightly with additional matcha powder and serve with a dollop of whipped cream if desired.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • matcha powder → cocoa powder for a classic chocolate mug cake
  • butter → coconut oil for a dairy-free version with subtle tropical flavor

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Overcooking the mug cake which results in a rubbery and dry texture instead of soft and moist
  • Using low-quality culinary matcha which results in a bitter and dull-colored cake
