Ingredients You’ll Need for Gluten-Free Brownie Mug Cake
- 4 tbsp gluten-free all-purpose flour – A must for the perfect texture.
- 3 tbsp brown sugar – Adds a caramel-like sweetness.
- 1 tbsp cocoa powder – Use good-quality cocoa for the richest flavor.
- 2 tbsp semi-sweet chocolate chips – Half for mixing, half for topping.
- 2 tbsp milk – Any type works, but whole milk adds creaminess.
- 1 tbsp vegetable oil – Or melted butter for extra flavor.
- ½ tsp vanilla extract – Because brownies need vanilla!
- Pinch of salt – Enhances the chocolate flavor.

How to Make the Best Gluten-Free Brownie Mug Cake
Step 1: Mix the Dry Ingredients
Grab your favorite microwave-safe mug and combine the flour, brown sugar, cocoa powder, and salt. Stir well with a fork to break up any clumps.
Step 2: Add the Wet Ingredients
Pour in the milk, vegetable oil, and vanilla extract. Mix until you have a smooth, lump-free batter.
Step 3: Fold in the Chocolate Chips
Gently stir in 1½ tablespoons of chocolate chips, leaving the rest for the topping.
Step 4: Microwave
Pop the mug into the microwave and heat on high for 60–90 seconds. Check after 60 seconds—the cake should be slightly gooey in the center.
Step 5: Cool & Top
Let the mug brownie cool for a minute before sprinkling the remaining chocolate chips on top. Then dig in while it’s still warm and melty!

- Avoid overmixing the batter; a gentle stir is all you need.
- Every microwave is different—start with 60 seconds and add time in 10-second intervals if needed.
