Gluten Free Chocolate Mug Cake (Printable)

A fudgy single-serving chocolate mug cake that's gluten-free, moist, and ready in under 7 minutes.

# 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)

# Directions:

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. Stir with a fork until a smooth batter forms, scraping the sides and bottom of the mug thoroughly.
03 - Fold in the chocolate chips if using, distributing them evenly throughout the batter.
04 - Microwave on high for 1 minute. Check for doneness — the cake should be set yet still moist in the center. If needed, continue microwaving in 10-second increments until fully set, being careful not to overcook.
05 - Let the cake rest in the mug for 1 to 2 minutes before serving. Enjoy directly from the mug.

# Expert Tips:

01 -
  • It delivers real fudgy chocolate cake texture, not the spongy rubber puck most mug recipes produce, and it does it without a single speck of gluten.
  • The entire process from craving to first bite takes less than seven minutes, which means you never have to negotiate with yourself about whether it is worth turning on the oven.
02 -
  • Microwave wattage varies wildly and at 1200 watts your cake may finish in fifty seconds while at 700 watts it could need ninety, so treat the one minute mark as a checkpoint rather than a rule.
  • The cake will collapse slightly when you remove it from the microwave and that is completely normal, not a sign you did something wrong.
03 -
  • Use a wider, shorter mug rather than a tall narrow one because the batter cooks more evenly and you get a better ratio of crispy edge to soft center.
  • Lightly spraying the inside of the mug with oil before adding ingredients makes cleanup almost effortless and helps the cake release cleanly if you want to turn it out onto a plate.
