Description

This molten lava cake in a mug recipe creates restaurant-quality dessert in just 3 minutes using your microwave. The secret is strategically placing chocolate chunks in the center to create that perfect flowing lava effect when you cut into the tender cake.


Ingredients

Scale

3 tablespoons all-purpose flour

3 tablespoons granulated sugar

2 tablespoons unsweetened cocoa powder

1/4 teaspoon baking powder

Pinch of salt

3 tablespoons milk

2 tablespoons melted butter

1/2 teaspoon vanilla extract

1 tablespoon dark chocolate chunks or chips

Powdered sugar for dusting


Instructions

1. In a microwave-safe mug, whisk together flour, sugar, cocoa powder, baking powder, and salt.

2. Add milk, melted butter, and vanilla extract. Mix until just combined – don’t overmix.

3. Add two-thirds of the batter to the mug. Place chocolate chunks in the center.

4. Top with remaining batter, covering the chocolate completely.

5. Microwave at 70% power for 45 seconds. Check if top looks set but slightly glossy.

6. If needed, continue microwaving in 10-second intervals until done.

7. Let rest for 30 seconds, then dust with powdered sugar and serve immediately.


Notes

Use a 12-ounce ceramic mug for best results. The cake will be very hot, so let it cool slightly before eating.

For extra indulgence, serve with vanilla ice cream or fresh berries.

The key to perfect molten center is not overcooking – start with 45 seconds and add time as needed.
