Gluten Free Chocolate Mug Cake (Printable)

A fudgy single-serving chocolate treat made gluten-free in the microwave, ready in minutes.

# What You'll Need:

→ Cake Base

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)
07 - 2 tablespoons neutral oil (canola or light olive oil)
08 - 1/4 teaspoon pure vanilla extract

→ Optional Add-ins

09 - 1 tablespoon chocolate chips
10 - Whipped cream or fresh berries for serving

# How-To Steps:

01 - In a microwave-safe mug (at least 12 oz), whisk together the gluten-free flour blend, cocoa powder, sugar, baking powder, and salt until evenly distributed.
02 - Add the milk, oil, and vanilla extract to the mug. Stir thoroughly until a smooth, lump-free batter forms.
03 - Fold in chocolate chips if desired, distributing them evenly throughout the batter.
04 - Microwave on high for 1 minute 30 seconds to 2 minutes, until the cake is set and springs back lightly when touched. Cooking times may vary depending on microwave wattage.
05 - Let the cake cool for 1 to 2 minutes before serving. Top with whipped cream or fresh berries if desired.

# Expert Advice:

01 -
  • It goes from a thought to a warm chocolate cake in under seven minutes, which is faster than finding your car keys.
  • The texture is genuinely moist and tender, not the rubbery sponge you might expect from a microwave.
  • Everything mixes right in the mug so there are no bowls to wash afterward.
  • It is endlessly adaptable depending on what milk, oil, or toppings you have on hand.
02 -
  • Microwave power varies enormously so start at one minute thirty seconds and add ten second bursts rather than risking a dried out cake.
  • Every gluten free flour blend behaves differently and some absorb more liquid, so if the batter looks thick as paste add another teaspoon of milk.
  • Check that your baking powder and cocoa powder are certified gluten free because cross contamination can sneak in through processed ingredients.
03 -
  • Grease the inside of the mug with a tiny smear of oil before adding ingredients so the cake slides out easily if you want to serve it on a plate.
  • The cake tastes even better if you let it cool for the full two minutes because the texture firms into something closer to a real baked cake rather than a steamed pudding.
