Instructions

  1. Step 1

    Mix flour, sugar, and cocoa powder in a microwave-safe mug until no lumps remain.

    Add egg, milk, and 1 tbsp melted butter. Stir until smooth, about 30 seconds.

  3. Step 3

    Microwave on high for 60-90 seconds until the top looks set but still moist. Center should jiggle slightly.

  4. Step 4

    Drizzle remaining 1 tbsp melted butter mixed with 1 tbsp cocoa powder over the top while hot.

  5. Step 5

    Let cool 1 minute, then eat straight from the mug with a spoon.
