There's something magical about that moment when you dig a spoon into a warm mug cake and hot molten chocolate flows out like lava. This Molten Lava Mug Cake is the ultimate answer to a chocolate craving that hits at 10 PM when you can't be bothered with a full dessert. It's decadent, it's indulgent, and it's ready in under five minutes from your microwave.
What makes this recipe truly special is how it delivers restaurant-quality dessert straight to your mug. The batter is simple—just pantry staples mixed together—but the magic happens when you hide that extra chocolate in the center before microwaving. As it cooks, that chocolate stays molten and gooey while the outside sets into the most tender cake you've ever had.
Ingredients
- All-purpose flour:0.25 cup
- Granulated sugar:3 tbsp
- Unsweetened cocoa powder:1.5 tbsp
- Baking powder:0.125 tsp
- Salt:Pinch
- Whole milk:3 tbsp
- Vegetable oil:1.5 tbsp
- Vanilla extract:0.25 tsp
- Semi-sweet chocolate chunk or square:1 oz
Instructions
-
In a microwave-safe mug, whisk together flour, sugar, cocoa powder, baking powder, and salt.
-
Add milk, oil, and vanilla extract. Stir until you have a smooth batter with no lumps.
-
Place the chocolate chunk in the center of the batter, pushing it down slightly so it's mostly covered.
-
Microwave on high for 1 minute 30 seconds to 2 minutes. The top should look set but still slightly moist.
-
Let it cool for about 30 seconds before eating straight from the mug or turning it out onto a plate.
Tips & Notes
- Don't overmix the batter—lumps are okay and actually help keep the cake tender.
- The size of your mug matters; use a standard 12-16 oz mug so the cake bakes evenly.
- If your chocolate piece is too large, break it into smaller chunks so it melts better.
- Top with a dollop of whipped cream or vanilla ice cream for maximum indulgence.
- You can prepare the dry ingredients ahead of time in a small jar for even faster assembly.
