Why You'll Love This Recipe
About the Ingredients
4 tablespoons (30g) all-purpose flour
Use plain all-purpose flour for the best structure. You can substitute with gluten-free 1:1 flour blend.
3 tablespoons (40g) granulated sugar
Regular white sugar works best. For a lower glycemic option, use coconut sugar but note it will darken the cake.
1/4 teaspoon baking powder
This is crucial for lift. Make sure it's fresh for the fluffiest result.
1/8 teaspoon salt
Just a pinch enhances the sweetness.
3 tablespoons (45ml) milk
Any milk works—dairy, almond, or oat. For a richer cake, use buttermilk.
2 tablespoons (30g) unsalted butter, melted
Melted butter adds richness. Substitute with coconut oil for a dairy-free version.
1/2 teaspoon vanilla extract
Use pure vanilla extract for the best flavor. You can also scrape half a vanilla bean.
1 large egg yolk
The yolk adds moisture and richness. You can use a whole egg for a slightly denser cake.
Tips & Tricks
- Mix the dry ingredients first to ensure even distribution of baking powder.
- Use a microwave-safe mug that holds at least 12 ounces to prevent overflow.
- Don't overcook—start with 60 seconds and add 10-second bursts if needed.
Pro Tips
Step-by-Step Instructions
1. Combine Dry Ingredients
In your mug, whisk together the flour, sugar, baking powder, and salt with a fork until well combined. This ensures no lumps and even leavening.
2. Add Wet Ingredients
Pour in the milk, melted butter, vanilla extract, and egg yolk. Stir until just combined—overmixing can make the cake tough. The batter should be smooth with no dry spots.
3. Microwave the Cake
Place the mug in the microwave and cook on high for 60 seconds. Check for doneness: the top should look set and spring back when lightly touched. If it's still wet on top, cook in 10-second increments until done, but do not exceed 90 seconds total.
4. Cool and Serve
Carefully remove the mug from the microwave (it will be hot). Let it cool for 1-2 minutes before digging in. The cake will continue to set as it cools.
Delicious Variations
Chocolate Chip
Fold in 1 tablespoon of mini chocolate chips before cooking.
Berry Swirl
Drop 1 teaspoon of your favorite jam into the batter and gently swirl with a knife.
Peanut Butter
Add a spoonful of peanut butter on top before microwaving for a melty center.

Frequently Asked Questions
Q: Can I make this vegan?
Yes, use a flax egg (1 tbsp ground flax + 2.5 tbsp water) instead of egg yolk, and swap butter for coconut oil and milk for non-dairy milk. The texture will be slightly denser but still delicious.
Q: Why is my mug cake rubbery?
The most common culprit is overmixing or overcooking. Stir just until combined and stop microwaving as soon as the top is set—usually around 60 seconds.
Q: Can I use self-rising flour?
Yes, omit the baking powder and salt if using self-rising flour. Keep the rest the same.
Q: Can I bake this in the oven?
Yes, pour the batter into a small ramekin and bake at 350°F (175°C) for 12-15 minutes, until a toothpick inserted comes out clean.
