Oreo Mug Cake

Oreo Mug Cake FI

A fluffy mug cake with tons of delicious Oreo flavor! Crumbled Oreos are mixed into the batter, and a whole Oreo is placed right in the center of the batter for a fun Oreo surprise.


  • 5 tablespoons all-purpose flour
  • 1 tablespoon + 2 teaspoons granulated sugar
  • 1/2 teaspoon baking powder
  • pinch salt
  • 1 1/2 tablespoons unsalted butter
  • 1/4 cup milk
  • 1/2 teaspoon vanilla extract
  • 3 Oreos, divided (plus more for garnish, optional)


1. In a small bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and pinch salt. Set aside.

2. Place the butter into a large microwave-safe mug (see notes). Place a folded paper towel on top of the mug to catch any potential spatter. Microwave on high for 30 seconds to melt the butter. If the butter is not fully melted, microwave for an additional 10 seconds.

3. Carefully pour the melted butter into the bowl with the dry ingredients, along with the milk and vanilla. Whisk together until no lumps remain, but do not overmix. 

4. Crumble up 2 of the Oreos with your fingers and add them to the batter. Mix just to combine.

5. Spoon about half of the batter into the mug, then place the remaining whole Oreo on top of the batter. Spoon the remaining batter on top. 

6. Microwave the mug cake on high for 90 seconds. Check the cake; if there is still wet batter on top, microwave again in 10 second increments until the cake is cooked through. Top with additional crumbled Oreos (optional) and enjoy!


If the baking powder is pebbly out of the canister, break it apart with your fingers or a fork before adding to the other dry ingredients. These little pebbles are hard to mix in fully, and getting a little piece of baking powder in the finished cake will taste quite bitter!

Be sure to use a mug that is at least 12 ounces to make sure the batter doesn’t overflow while it cooks. For extra insurance, you can place the mug onto a microwave-safe plate to catch any potential drips. And of course, please make sure that the mug is microwave-safe!

When crumbling the Oreos to add to the cake batter, you can either crumble them quite fine for a more even texture, or leave the pieces larger for bigger chunks of Oreo flavor in each bite!
