Best Gluten Free Mug Cake Recipe
A quick gluten free chocolate mug cake you mix in a mug and cook in the microwave for an easy single-serve dessert.
Ingredients
Mug Cake
- 3 tablespoons gluten-free all-purpose flour I love King Arthur or Cup4Cup. If you’re grain-free, swap 2 tablespoons almond flour + 1 tablespoon tapioca starch. Don’t use straight almond flour or it’ll stay mushy.
- 1 tablespoon + 1 teaspoon unsweetened cocoa powder Dutch-processed gives a deeper flavor, but regular works fine.
- 1/2 teaspoon baking powder Gives it that fluffy, cakey rise. Double-check it’s gluten-free!
- pinch salt Balances the sweet.
- 2 tablespoons coconut sugar or maple syrup Maple adds moisture; coconut sugar brings deeper flavor.
- 1 tablespoon melted coconut oil or butter Coconut oil is lighter; butter tastes like classic cake.
- 2 tablespoons milk or plant-based milk Almond, oat, or coconut all work. I use unsweetened almond most often.
- 1 teaspoon vanilla extract Adds warmth and ties it all together.
- 1 tablespoon chocolate chips, nuts, or berries Optional. Emma’s favorite is mini chocolate chips and a spoon of peanut butter in the center.
Instructions
- Combine dry ingredients in a mug: Use a 10–12 oz microwave-safe mug (too small and it’ll overflow). Whisk flour, cocoa, baking powder, and salt directly in the mug to prevent clumps and ensure even rise.
- Add wet ingredients: Stir in sugar or syrup, melted oil, milk, and vanilla until smooth and glossy. Don’t overmix—just mix until combined.
- Fold in mix-ins: Gently add chocolate chips, nuts, or berries. Those molten chocolate pockets are pure joy.
- Microwave carefully: Cook on 50–70% power for 60–90 seconds. Start around 70 seconds. The edges should look set and the center slightly soft (it finishes setting as it rests).
- Cool slightly and serve: Let the mug cake sit for 30 seconds. Top with whipped cream, powdered sugar, or an almond butter drizzle.

Rachel’s Tips & Tricks
Best Mugs to Use: Stick to 10–12 oz mugs with straight sides. Avoid tiny teacups that overflow or wide soup mugs where the cake spreads too thin.
Texture Trouble?: If it’s dry, your microwave might be too strong; reduce cook time by about 10 seconds. If it’s soggy, microwave another 10–15 seconds or check your flour ratio.
Make-Ahead? Sorta.: Mix the dry ingredients and store in a small jar. Add the wet ingredients and microwave when the craving hits — instant cake magic.
Budget Swaps: Use melted butter instead of coconut oil. Skip the chips and add a pinch of cinnamon for big flavor on a budget.
Fun Variations: Chocolate + espresso powder for a mocha mug cake; add 2 tablespoons mashed banana for a banana-choco version; swirl in a spoon of peanut butter or almond butter; use cinnamon + a little maple for a “cinnamon roll” flavor; or add a square of dark chocolate in the middle for lava cake vibes.
