Why You’ll Love This Recipe
I love how easy and satisfying this mug cake is. It takes less than 5 minutes from start to finish, and it gives me all the indulgence of a real chocolate cake with almost no cleanup.

Ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
-
All-purpose flour
-
Cocoa powder
-
Granulated sugar
-
Baking powder
-
Pinch of salt
-
Milk (dairy or non-dairy)
-
Vegetable oil or melted butter
-
Vanilla extract
-
Chocolate chips or chopped chocolate (optional)
Directions
-
In a microwave-safe mug, I mix the flour, cocoa powder, sugar, baking powder, and salt.
-
I stir in the milk, oil, and vanilla extract until smooth and no dry pockets remain.
-
If I’m using chocolate chips, I fold them into the batter or sprinkle some on top.
-
I microwave the mug on high for 60 to 90 seconds, depending on the strength of my microwave — just until the cake is set but still slightly gooey in the center.
-
I let it cool for a minute or two before digging in — sometimes I top it with whipped cream, ice cream, or a drizzle of peanut butter.
Servings and timing
This recipe makes 1 generous serving and takes about 2 minutes to prep and 1 to 2 minutes to cook. It’s perfect for an after-dinner dessert or late-night chocolate craving.
Variations
I sometimes add a spoonful of peanut butter, Nutella, or caramel to the center for a molten surprise. When I want a mocha twist, I add a pinch of instant coffee. For a richer flavor, I use brown sugar instead of white. I’ve also tried it with almond or oat milk and coconut oil for a dairy-free version.
storage/reheating
This cake is best enjoyed fresh. If I have leftovers (which is rare), I cover the mug and store it in the fridge for up to 1 day. To reheat, I microwave it for 10–15 seconds to soften it up again.
FAQs
Can I use self-rising flour?
Yes, if I use self-rising flour, I skip the baking powder and salt — it already has leavening in it.
What size mug should I use?
I use a 10–12 oz microwave-safe mug to prevent overflowing. It gives the cake room to rise and cook evenly.
Why did my cake turn out rubbery?
It was probably overcooked. I microwave it just until the top is set but still soft inside — usually around 70 to 90 seconds, depending on the microwave.
Can I make this without eggs?
Yes — this recipe doesn’t use any eggs. It stays soft and moist thanks to the milk and oil.
Can I double the recipe?
I’ve doubled the ingredients and split them into two mugs to avoid overflow. I microwave each one separately for even cooking.
