This Oreo mug cake starts with a base of fluffy vanilla cake studded with crushed Oreos. For extra cookies-and-cream goodness, a whole Oreo is tucked into the center of the batter for a gooey surprise.
I’m a big fan of mug cakes — they’re quick, comforting, and satisfying. If you’ve enjoyed my other mug cake recipes like Apple Cinnamon, Gingerbread, or Chocolate Berry, you’ll love this Oreo version. It comes together fast and delivers warm, indulgent flavor with minimal fuss.
This Oreo mug cake is light, sweet, and packed with cookie flavor. You can have a freshly cooked treat in under 10 minutes, and the whole Oreo hidden in the center melts into a delightful, creamy pocket of filling.
Recipe ingredients
Ingredient notes
- Milk: I used 2% milk, but whole milk or any non-dairy milk works fine.
- Butter: The recipe calls for unsalted butter. If you only have salted butter, skip the pinch of salt in the recipe.
- Oreos: Regular Oreos are used here, but feel free to try Double Stuf or flavored varieties if you prefer.
Step by step photos
1. Whisk the dry ingredients together in a small bowl and set aside.
2. Melt the butter in the microwave in the mug you’ll use to bake. Combine the melted butter, milk, and vanilla with the dry ingredients.
3. Whisk until smooth, taking care not to overmix.
4. Crumble two Oreos into the batter and fold them in for texture and flavor.
5. Spoon about half the batter into your mug.
6. Place one whole Oreo on top of the batter in the mug.
7. Cover the whole cookie with the remaining batter.
8. Microwave until the cake is set on top and springs back when touched. Top with ice cream, whipped cream, or extra crumbled Oreos if desired. Enjoy warm.
Tips and tricks
- Break up any pebbly baking powder before mixing. Small lumps can be bitter if they aren’t fully incorporated.
- When crumbling Oreos, choose finer crumbs for even distribution or larger chunks for more texture.
- Measure carefully—small batches are sensitive to ingredient amounts, and accurate measurements help ensure the best texture.
Recipe FAQs
Use a microwave-safe mug that’s large enough to prevent overflow. A mug of at least 12 ounces gives the cake room to rise while cooking and reduces the risk of spills.
After the initial 90-second cook time, check the top—there should be no wet batter and it should feel springy. If needed, microwave in 10-second increments until set. Microwaves vary, so times may need slight adjustment.
For a simple finish, sprinkle extra crumbled Oreo on top. For a more decadent treat, add whipped cream or a scoop of vanilla or cookies-and-cream ice cream.

- Total Time: 7 minutes
- Yield: 1 mug cake
- Category: Dessert
- Method: microwave
- Cuisine: American
Ingredients
Scale
- 5 tablespoons all-purpose flour
- 1 tablespoon + 2 teaspoons granulated sugar
- ½ teaspoon baking powder
- pinch salt
- 1½ tablespoons unsalted butter
- ¼ cup milk
- ½ teaspoon vanilla extract
- 3 Oreos, divided (plus more for garnish, optional)
Instructions
1. In a small bowl, whisk together the flour, sugar, baking powder, and a pinch of salt. Set aside.
2. Place the butter in a microwave-safe mug and cover with a folded paper towel to prevent splatter. Microwave on high for 30 seconds, then heat an additional 10 seconds if needed to fully melt.
3. Pour the melted butter into the bowl with the dry ingredients. Add the milk and vanilla, then whisk until smooth but not overmixed.
4. Crumble 2 Oreos into the batter and stir gently to combine.
5. Spoon about half of the batter into the mug. Place the whole Oreo on top, then cover it with the remaining batter.
6. Microwave on high for 90 seconds. If the top is still wet, microwave in 10-second increments until the cake is set. Top with extra crumbled Oreos, ice cream, or whipped cream if desired and serve warm.
Notes
If your baking powder is lumpy, break it up before adding to the dry ingredients to avoid bitter pockets. Use a mug that holds at least 12 ounces to prevent overflow, and place the mug on a microwave-safe plate for extra protection against drips. Crumble Oreos finely for even texture or leave bigger pieces for more cookie chunks.
