A chocolate mug cake is the ultimate quick-fix dessert. In just a few minutes, I can satisfy my chocolate cravings with a warm, fluffy cake made right in the microwave.

Why You’ll Love This Recipe
I love how this chocolate mug cake comes together in under 5 minutes using basic pantry staples. There’s no need to preheat the oven or dirty multiple dishes. It’s great when I want something sweet without the hassle. Plus, I can easily customize it with add-ins like chocolate chips, peanut butter, or a scoop of ice cream on top.
Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
4 tablespoons all-purpose flour
4 tablespoons granulated sugar
2 tablespoons unsweetened cocoa powder
1/8 teaspoon baking powder
A pinch of salt
3 tablespoons milk
2 tablespoons vegetable oil
1/4 teaspoon vanilla extract
1 tablespoon chocolate chips (optional)
Directions
In a microwave-safe mug (roughly 12 oz size), I whisk together the flour, sugar, cocoa powder, baking powder, and salt.
I add the milk, vegetable oil, and vanilla extract to the dry ingredients and mix until smooth.
If I’m feeling extra indulgent, I fold in the chocolate chips for gooey pockets of chocolate.
I microwave the mug on high for about 70–90 seconds, or until the cake rises and sets on top. It should still be slightly moist in the center.
I let it cool for a minute or two before digging in—sometimes I top it with whipped cream or ice cream.
Servings and timing
This recipe makes 1 serving. Prep time: 3 minutes Cook time: 1–1.5 minutes Total time: 5 minutes
Variations
I like to switch things up depending on my mood. Sometimes I add a spoonful of peanut butter or Nutella in the center before microwaving for a molten core. A dash of cinnamon or espresso powder also adds a lovely twist. When I want a slightly healthier version, I swap the sugar for maple syrup and use almond milk instead of regular milk.
Storage/Reheating
This mug cake is best enjoyed fresh, straight from the microwave. If I ever have leftovers (rarely!), I cover the mug and store it in the fridge for up to a day. To reheat, I microwave it for about 15–20 seconds, but I try not to overdo it so it doesn’t dry out.
FAQs
How do I know when the mug cake is done?
I check if the top looks set and springs back slightly when touched. If it’s still wet in the center, I microwave in 10-second bursts.
Can I make this without cocoa powder?
Yes, but it won’t be chocolate-flavored. I could try adding cinnamon, vanilla, or even mashed banana for a different taste.
Why did my mug cake turn out rubbery?
Overcooking is often the culprit. I make sure not to microwave it for too long and always check at the 70-second mark.
Can I use self-rising flour?
Yes, I can skip the baking powder if I’m using self-rising flour, since it already contains leavening agents.
What kind of mug should I use?
I go for a microwave-safe mug that holds at least 12 oz to prevent overflow while the cake rises.
Conclusion
This chocolate mug cake is my go-to for quick dessert satisfaction. It’s simple, flexible, and ready in minutes—ideal when I want a warm, homemade treat without turning on the oven. Whether I keep it classic or experiment with mix-ins, it never disappoints.
