What you will need
This recipe uses 6 simple ingredients that you can find at any grocery store:
- 4 tablespoons all-purpose flour
- 3 tablespoons granulated sugar
- 0.5 teaspoon ground cinnamon
- 0.25 teaspoon baking powder
- 3 tablespoons whole milk
- 2 tablespoons unsalted butter melted
Step by step instructions
Step 1: Combine Dry Ingredients
Add the flour, sugar, cinnamon, and baking powder directly into a large microwave-safe mug. Stir the dry ingredients together thoroughly with a fork until evenly combined with no lumps.
Step 2: Add Wet Ingredients
Pour the melted butter and milk into the mug with the dry ingredients. Stir everything together vigorously with the fork until a smooth lump-free batter forms and no dry flour remains at the bottom.
Step 3: Microwave the Cake
Microwave the mug on high power for 60 to 90 seconds. Check at 60 seconds by touching the center gently. It should spring back and look just barely set in the very center when done.
Step 4: Rest and Enjoy
Let the mug sit for 1 full minute before eating as the cake continues to cook from residual heat and will firm up to the perfect texture. Eat directly from the mug with a spoon.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- whole milk → any plant-based milk such as almond or oat milk for a dairy-free version
- all-purpose flour → a 1 to 1 gluten-free flour blend for a gluten-free mug cake that works just as well
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Overmixing the batter after combining wet and dry ingredients which develops gluten and results in a tough rubbery cake texture
- Microwaving the cake for too long which dries it out completely and makes it chewy and dense instead of soft and fluffy
