Crush 2-3 Oreos into small pieces using a fork or a food processor. If using a fork, place the cookies in a microwave-safe mug and mash until they become small crumbs (about 1 minute).

Pour in 1/4 cup of milk and stir until the mixture is smooth. You can add 1 tablespoon of chocolate chips or other toppings if desired.

Add 1/4 teaspoon of baking powder and mix it in thoroughly.

Place the mug into the microwave and cook on high for 1 1/2 to 2 minutes. Keep an eye on it to prevent overcooking. The cake is done when it has risen and is firm to the touch.

Once cooked, allow the cake to cool for a minute or two.

Optionally, add a dollop of whipped cream or a drizzle of chocolate syrup on top.

Serve the Oreo mug cake hot and enjoy!
