I’m all about easy, and this microwave chocolate mug cake might be the easiest dessert I’ve ever made! I always keep the ingredients on hand in case I get a rare night alone so I can make this double chocolate mug cake and indulge. It takes 6 minutes from start to finish, which is just about the limit of how long I can wait for a little treat, and it’s chock-full of gooey chocolate chips. Yum!
There’s not a whole lot I love more than cuddling up on the couch, turning on my favorite show, and eating this microwave chocolate mug cake at the end of a long day! This mug cake is so rich and delectable, you’ll forget that you made it in the microwave. Although the texture of this mug cake is light and fluffy, the chocolate flavor is extremely rich and satisfying. I love how rich the chocolate is without being dense!
What’s in This Microwave Chocolate Mug Cake Recipe?
- Flour: All-purpose flour gives the cake structure.
- Cocoa Powder: 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.
- Sugar: Granulated sugar sweetens the cake.
- Baking Powder: Helps the cake rise to become light and fluffy.
- Milk: 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!
- Vanilla: Pure vanilla extract adds warmth to the cake.
- Mini Chocolate Chips: 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.

How to Store
Store leftover microwave chocolate mug cake tightly covered with plastic wrap at room temperature for up to 1 day. Enjoy at room temperature, or gently reheat in the microwave.
Tips for Success
- 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.
- When measuring out your flour, don’t pack it into the measuring cup. Spoon then level the flour or you will have a dense mug cake.
- Microwave in 30-second increments or your mug might overflow. Still delicious, but a little messy.
- 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.
- 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!
- 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.
