Step 1: Mix the Dry Ingredients

In a microwave-safe mug (at least 10 oz to avoid overflow), whisk together:

• Flour

• Cocoa powder

• Sugar

• Baking powder

• Salt

Step 2: Add the Wet Ingredients

Stir in:

• Milk

• Oil

• Vanilla extract

Mix until smooth with no dry pockets, but don’t overmix.

Step 3: Add the Lava Center

Press the chocolate chips or chunk of chocolate into the center of the batter. Don’t stir it in—this is your gooey core!

Step 4: Microwave

Microwave on high for 60–70 seconds. The top should look set but jiggle slightly when you shake the mug. Avoid overcooking, or you’ll lose the lava effect.

Step 5: Cool and Enjoy

Let sit for 1 minute (it will be hot!). Top with powdered sugar, whipped cream, or a scoop of vanilla ice cream if desired.
