Ingredients and variations
Use simple pantry staples to make the best chocolate mug cake. Check out my ingredient recommendations and tips as you gather everything you'll need. See recipe card for full list of ingredients and quantities.
- Salted butter: Using salted butter helps to enhance the chocolate flavor. If you only have unsalted butter, add a small pinch of salt to the batter.
- Semi-sweet chocolate: I chopped chocolate from a semi-sweet chocolate bar. Using chocolate chips results in a different texture because of the stabilizers used in chips. Extra chocolate from the bar can be shaved on top.
- Granulated sugar
- Vanilla extract: You can experiment with other flavors like almond or mint.
- Large eggs
- All-purpose flour
- Dutch-processed cocoa powder: This type of cocoa powder is treated with alkaline so it has a darker color and less acidic chocolate taste.
- Baking powder

Tara's top tips
🥣 Mix the batter well: For the best texture, it's important to mix the batter well to fully incorporate all the flour and egg. There shouldn't be any dry pockets in the batter. Once everything is incorporated stop stirring to prevent overmixing and developing too much gluten (which would result in a chewy cake).
☕️ Don't overfill the mugs: Mug cakes are notorious for overflowing in the microwave. Make sure to use a mug with a wide opening and don't fill more than ¾ full. If you are nervous about the mug you are using, try filling it ½ way the first time.
⏲️ Underestimate the cooking time: The cooking time will vary depending on the wattage of your microwave. Since mug cakes cook quickly, overcooking by even a few seconds can make a big difference in texture. As you get familiar with how quickly your microwave cooks, err on the side of caution. Cook for the lowest amount of time and then add a few more seconds until the cakes are done.
👀 Look for clues to know when it is done: A fully cooked mug cake will look firm on top and bounces back when touched. If the top looks wet and shiny or has a sagging center, it probably needs a few more seconds to cook. If you prefer a fudgier texture, slightly undercook the cakes.
💨 Let them cool down: Your mug cakes will be very hot when they first come out of the microwave. Give them 1 to 2 minutes to cool down before enjoying.
Variations and mix-ins
- Molten center: Place a chocolate truffle in the center before baking for a molten middle.
- Nutella: Stir a few tablespoons into the batter.
- Peanut Butter: Add a dollop to the top of the cakes right when they come out of the microwave.
- Cinnamon: Stir ½ teaspoon of cinnamon into the batter.
- Swap the extract: Use almond, mint, or orange extract in place of vanilla.
- Flavored baking chips: Instead of chopped chocolate, sprinkle the top with your favorite chocolate, peanut butter, or peppermint baking chips.
- Other mix-ins: Add a small handful of chopped candy bar, M&Ms, chopped nuts, or shredded coconut to the batter.
- Other toppings: Drizzle the top with dessert sauce like hot fudge, caramel, or strawberry sauce. Or, top with fresh whipped cream and fresh berries!
Equipment
I love these wide mouth mugs for mug cakes. They come in a variety of colors and are porcelain instead of ceramic, so they don't overheat in the microwave.
FAQ
Mug cakes become dry and rubbery when they are cooked for too long. Make sure to mix the batter so all the ingredients are incorporated and don't over-bake them.
When being microwaved, mug cakes rise and bake very quickly. If you fill the mug more than ¾ full or try to bake them in a mug with a narrow mouth, they are more likely to overflow. If you are worried that your mug is too narrow, try filling halfway the first time you try the recipe.
This recipe makes 2 to 3 individual mug cakes depending on the size of the mugs. Each mug cake is a single-serve portion and just right for one person.
Most mug cake recipes are specifically designed to be baked in a microwave. If you want to try baking it in the oven, you will need to put the batter into an oven-safe ramekin and experiment with the baking temperature and time. Watch the cakes closely so they don't get overbaked.
This recipe was formulated and tested with eggs. The cake won't set properly without them.
