Start by selecting a microwave-safe mug that can hold at least 10 ounces. To prevent sticking and ensure an easier cleanup, lightly mist the inside of the mug with nonstick spray or grease it with a little butter

This small step makes all the difference when enjoying your treat!

Place four Oreo cookies into your prepared mug. Using either your fingers or a fork, crush them into fine crumbs. The finer the crumbs, the smoother your batter will be. If you’re using a food processor or blender, pulse the Oreos until they resemble sand-like particles

Pour three tablespoons of milk over the crushed Oreos. Stir gently until the mixture forms a paste-like consistency. Let it sit for about 30 seconds; this allows the cookie crumbs to soften and absorb the liquid fully

Sprinkle in ¼ teaspoon of baking powder and mix thoroughly. This leavening agent helps the batter rise slightly during microwaving, giving your mug cake a light and fluffy texture instead of making it dense or rubbery

Be careful not to overmix just enough to incorporate everything evenly.

Pop your mug into the microwave and heat on high for 60 seconds . After one minute, check if the top looks set. If it still appears jiggly in the center, continue microwaving in 10-second intervals , checking frequently to avoid overcooking

Overcooking can lead to a dry or hard texture, so keep an eye on it!
