Pro Tips for the Perfect Chocolate Lava Mug Cake
- Choose the Right Mug: Use a mug that holds at least 12 oz to prevent overflow while cooking. Make sure it’s microwave-safe!
- Don’t Overcook: Mug cakes cook quickly. Start with 50-60 seconds and add a few seconds at a time if needed to avoid a dry texture.
- Molten Center Hack: Push a piece of chocolate or a dollop of Nutella into the batter for an extra gooey surprise.
- Sift Your Cocoa Powder: For a smoother texture, sift the cocoa powder to remove lumps.
- Serve Immediately: Mug cakes are best enjoyed fresh and warm, straight out of the microwave.
Substitutions and Variations
- Milk: Use almond milk, oat milk, or coconut milk for a dairy-free option.
- Butter: Swap for coconut oil or vegetable oil for a vegan version.
- Flour: Use gluten-free all-purpose flour for a gluten-free mug cake.
- Extra Flavors: Add a pinch of cinnamon, espresso powder, or orange zest to enhance the chocolate flavor.
Make Ahead Tips
Mug cakes are best made and eaten fresh. However, you can pre-measure and mix the dry ingredients in a small airtight container so it’s ready to go when the craving strikes. Simply add the wet ingredients when you’re ready to bake!
Instructions: How to Make Chocolate Lava Mug Cake
Step 1: Combine the Dry Ingredients
In a 12 oz microwave-safe mug, add 1/4 cup flour, 2 tablespoons cocoa powder, 1/4 teaspoon baking powder, and 2 tablespoons granulated sugar. Mix with a fork until well combined.
Step 2: Add the Wet Ingredients
To the dry ingredients, add 1/4 cup milk, 2 tablespoons melted butter, and 1/4 teaspoon vanilla extract. Stir until the batter is smooth and there are no lumps.
Step 3: Add the Chocolate Center
Gently press 1 tablespoon of chocolate chips into the center of the batter. Do not mix it in—this will create the gooey molten center.
Step 4: Microwave the Cake
Place the mug in the microwave and cook on high for 50-60 seconds. The top should be set but still slightly soft to the touch. Avoid overcooking to keep the center molten.
Step 5: Garnish and Serve
Remove the mug from the microwave (carefully—it will be hot!) and let it cool for 1-2 minutes. Dust with powdered sugar, add a dollop of whipped cream, or enjoy it straight from the mug with a spoon!
Leftovers and Storage Tips
Mug cakes are best enjoyed fresh and warm. If you must store it, cover the mug tightly with plastic wrap and refrigerate for up to 1 day. Reheat in the microwave for 10-15 seconds before eating, though note the molten center may solidify.

This chocolate lava mug cake is everything you love about dessert, wrapped up in a quick, single-serving treat.
