Build Microwave Lava Mug Cake (TikTok!) Step by Step

Step 1: Melt the Butter
Begin by melting the butter in your microwave-safe mug. Heat it for about 20-30 seconds, or until it’s completely melted.
Step 2: Combine Sugar and Butter
Add the white sugar to the melted butter and mix well until it’s fully combined. This will create a sweet base for your cake.
Step 3: Add Hot Water
Pour in the boiling or hot water and stir again until the mixture is smooth. The heat will help dissolve the sugar completely.
Step 4: Mix in Cocoa Powder
Next, add the cocoa powder to the mug. Stir until the cocoa is fully incorporated and the mixture is nice and smooth.
Step 5: Incorporate Self-Rising Flour
Sprinkle in the self-rising flour and mix until everything is well combined. Be careful not to over-mix; a few lumps are perfectly fine.
Step 6: Add the Chocolate
Break the dark or semi-sweet baking chocolate into small pieces and fold them into the batter. These pieces will melt beautifully during cooking, creating that signature lava effect.
Step 7: Microwave the Cake
Place the mug in the microwave and cook on high for about 40-60 seconds. Keep an eye on it, as cooking times may vary based on your microwave’s wattage. You want the cake to be set on the outside but still slightly gooey in the center.
Step 8: Let it Cool and Enjoy!
Once done, carefully remove the mug from the microwave (it will be hot!) and let it cool for a minute or two. Then, dig in with a spoon and enjoy the molten chocolate goodness!
Dairy-Free/Gluten-Free Swaps

If you’re looking to make this Microwave Lava Mug Cake (TikTok!) fit specific dietary needs, here are some easy swaps:
- Dairy-Free: Substitute the butter with coconut oil or a dairy-free margarine. For the chocolate, use dairy-free dark chocolate.
- Gluten-Free: Replace self-rising flour with a gluten-free all-purpose flour blend that includes a leavening agent. You might need to adjust the amount slightly for best results.
With these substitutions, everyone can enjoy this indulgent treat!
Troubleshooting Tips
Making a Microwave Lava Mug Cake (TikTok!) is generally straightforward, but here are some tips to ensure success:
- Too Dry: If your cake turns out dry, cut back on the cooking time. Every microwave is different, so start with less time and check for doneness.
- Overflow: If your mug is too small, the batter may overflow. Use a larger mug to prevent this from happening.
- Not Gooey Enough: If you find that the center isn’t gooey, try microwaving for an additional 10-15 seconds at a time until you achieve your desired consistency.
With a little patience and practice, you’ll master this recipe in no time!
