5-Minute Chocolate Lava Mug Cake

Method

  1. Mix flour, sugar and cocoa in a large microwave-safe mug.
  2. Add egg, milk and oil. Whisk until smooth.
  3. Push 2 chocolate squares into center of batter.
  4. Microwave 60-90 seconds until edges are set but center jiggles.
  5. Let rest 30 seconds - it continues cooking.
  6. Top with ice cream or whipped cream.

Microwave times are for a 1,000 W microwave, the usual US size. In an 800 W microwave (common in the UK and Europe) add about a quarter more time; at 1,200 W check a little early.

This 5-Minute Chocolate Lava Mug Cake is warm, rich, and irresistibly gooey — made right in the microwave. With simple pantry ingredients like cocoa powder, flour, sugar, and chocolate, this easy dessert creates a molten lava center in just minutes.
