What is a Microwave Mug Cake, Anyway?
Before we go any further, let’s first cover what exactly a microwave mug cake is. As the name suggests, it’s a cake prepared in a mug and baked in the microwave.
Unlike traditional cake recipes, coffee mug cakes serve just one person. In addition, they cook in the microwave, not the oven — most mugs shatter to pieces under such intense heat. Because of their ease and convenience, mug cakes have gained lots of popularity, and we’re not complaining!
Ingredients
Below is an overview of the ingredients and instructions for this recipe. Don’t forget to scroll down to the recipe card below for the complete details!
- Flour – Regular all-purpose flour forms the base of the cake batter.
- Unsweetened Cocoa Powder – This creates a rich chocolate flavor base.
- Espresso Powder – This enhances the chocolate taste. Feel free to use decaf varieties if needed.
- Milk – Any milk you like best will work.
- Butter – We recommend using unsalted butter to avoid overpowering the cake.
- Egg – This adds structure to the cake, helping it hold its shape.
- Dark Chocolate Chunks – Feel free to swap chocolate chips, and use semi-sweet, milk, or white chocolate instead!
Espresso vs Coffee
Although commonly confused, espresso and coffee are not the same things! Both drinks feature a coffee bean base. However, espresso is a thicker, more concentrated liquid.
Meanwhile, coffee has a higher ratio of water to coffee grounds. As a result, it has a milder taste and a thinner consistency.
Does it Matter What Kind of Espresso I Use?
We recommend using an instant espresso powder. However, any espresso powder you have on hand or find in the store will work just fine!
Can I Use Coffee Grounds Instead of Espresso Powder?
We recommend sticking with espresso powder if you can find it. However, coffee grounds will work in its place if you’re in a pinch.
How to Make Chocolate Coffee Cake in a Mug
- Mix.To start, add all the dry ingredients to a coffee mug, and mix until they are well combined.
- Stir.Then, stir in the wet ingredients, until a smooth batter forms.
- Top.Top your mug cake recipe with chocolate chunks. Or, if you’re feeling extra indulgent, press a large chocolate square into the center.
- Microwave.Place your mug in the microwave, and cook on high until the cake sets. You should be able to insert a toothpick into the center and pull it out clean, apart from the gooey chocolate chunks, of course!

Baking Tips
- Don’t Overbake!If you leave your coffee mug cake in the microwave for too long it will become way too dry. To prevent this from happening, be sure to keep an eye on it while cooking, and pull it out as soon as the batter has set.
- Use the Right Size Mug.Most conventional coffee mugs will work just fine. The trick is to allow an extra two inches from the top of the batter. Otherwise, the cake is likely to explode while cooking, leaving you with a mess!
- Measure Carefully.We recommend using a food scale for the most accurate results and a soft, rich cake. However, if that’s not an option, the spoon and level method is your next best bet!
Serving Suggestions
This chocolate coffee mug cake recipe is best served warm! We recommend topping it with a scoop of vanilla ice cream, but you could also add whipped cream, sprinkles, or fresh fruit!
Common Questions
Can I make this recipe in the oven?
No, this coffee mug cake recipe is only suitable for the quick cooking time of a microwave.
Can I double the recipe?
We do not recommend doubling the ingredients as typical mugs will not be large enough to hold all the batter. To make a double portion, we recommend using two separate mugs!
Are microwave mug cakes safe to eat?
Yes! Mug cakes are completely safe to consume. Just make sure to microwave them long enough for the cake batter to cook completely!
Can I prepare this recipe ahead of time?
Yes, feel free to store your coffee mug cake covered in the fridge for up to one day. Then, when you’re ready to eat, justreheat it in the microwave for 15-30 secondsor just long enough for it to warm. Just make sure not to overcook your cake, or it will become dry and rubbery!
