Gluten Free Chocolate Mug Cake (Print version)

A moist, fudgy gluten free chocolate mug cake ready in minutes using simple pantry staples.

# What you'll need:

→ Dry Ingredients

01 - 3 tablespoons gluten-free all-purpose flour blend
02 - 2 tablespoons unsweetened cocoa powder
03 - 3 tablespoons granulated sugar
04 - 1/4 teaspoon baking powder
05 - Pinch of salt

→ Wet Ingredients

06 - 3 tablespoons milk (dairy or non-dairy alternative)
07 - 2 tablespoons vegetable oil (or melted coconut oil)
08 - 1/4 teaspoon pure vanilla extract
09 - 2 tablespoons chocolate chips (optional)

# How to make it:

01 - In a microwave-safe mug (at least 12 oz), whisk together the gluten-free flour, cocoa powder, sugar, baking powder, and salt until evenly blended.
02 - Pour in the milk, vegetable oil, and vanilla extract. Mix thoroughly with a fork until a smooth, lump-free batter forms, scraping the sides and bottom of the mug to ensure nothing is left unmixed.
03 - Gently stir in the chocolate chips if using, distributing them evenly throughout the batter.
04 - Microwave on high power for 1 minute. Check for doneness — the cake should be set on the edges yet still slightly moist in the center. If undercooked, continue microwaving in 10-second bursts until just done, being careful not to overcook.
05 - Let the mug cake rest for 1 to 2 minutes before enjoying directly from the mug.

# Expert suggestions:

01 -
  • This cake is dangerously easy to make, ready before your coffee finishes brewing.
  • The texture walks a perfect line between brownie and souffle, fudgy inside with a tender crumb.
02 -
  • Overcooking by even fifteen seconds turns this from fudgy to rubbery, so always undercook slightly and let the residual heat finish the job.
  • Every microwave is different, so your first attempt is really a calibration round worth remembering for next time.
03 -
  • Spray the inside of the mug with a quick burst of cooking spray so the cake slides out easily if you want to serve it on a plate.
  • Stir the batter longer than you think necessary because pockets of dry flour hiding at the bottom are the most common mistake and the easiest to avoid.
