How to Make Chocolate Mug Cake
Be sure to see the recipe card below for full ingredients & instructions!
- Whisk together flour, cocoa powder, cane sugar, and baking powder.
- Stir in the milk, butter, and vanilla.
- Pour the batter into a prepared mug.
- Top with chocolate chips.
- Microwave for 90 seconds.
- Enjoy!


While you can use any unsweetened cocoa powder you prefer, I like to use Dutch-process cocoa powder here because there isn’t any baking soda to neutralize the acidity of natural cocoa powder.
Mug cakes require a special kind of science, and I’ve found that whole milk works the best for this recipe! Skim milk should also work well in the mug cake batter. However, if you’re looking for a dairy-free alternative, opt for almond or oat milk, as they are fairly similar to whole milk in flavor and consistency. Just note that changing your milk choice might affect the flavor and texture of the mug cake!
That’s actually the desired consistency! If you place your fingertips on the top of the mug cake and a small amount of cake residue sticks to you, that means it’s perfectly baked and ready to eat. If you microwave your mug cake for too long, it will harden and not have the desired consistency. Be careful to not go over 90 seconds unless it’s truly undercooked!
Just like ovens, all microwaves can be a little bit different from one another. If at the 90-second mark, your cake is still undercooked, continue microwaving in 10-second increments until it’s fully baked.


Recipe Tips and Tricks
- Feel free to add more flavorful chips in there like peanut butter or butterscotch chips! While I like to keep mine exclusively chocolate, you can tailor your mug cake however you’d like.
- Don’t forget to spray your mug with cooking spray! I’ve found that butter flavor works the best, as it compliments the flavor of the cake. If you forget to spray, you’ll probably be scrubbing cake residue from your mug for quite some time.
- If at first your mug cake doesn’t turn out to be picture perfect, that’s okay! Sometimes, even easy recipes like this need a little practice to get perfect. Plus, even if it’s not too pretty, it’ll still be delicious.
