Oreo Mug Cake
This Oreo Mug Cake is the perfect small batch treat for one! It’s light, fluffy, and full of irresistible cookies and cream flavor!
Easy Oreo Microwave Cake
When you’re craving a sweet treat and you want it now, whipping up a whole batch of cupcakes or your favorite layer cake isn’t exactly an option. That’s where mug cakes come in.
This Oreo Mug Cake is simple to make, with only a handful of ingredients that you probably already have on hand and a few minutes of prep time. It bakes in the microwave in less than 2 minutes, so all that’s left to do is grab a spoon and enjoy!
Now, if you’re a mug cake connoisseur, you’ve probably noticed that some versions are a little bit disappointing, to put it mildly. They’re spongy and eggy, and just not very appetizing. This mug cake won’t disappoint—it’s not spongy or eggy. Instead, it has a light cake-y texture.
- 1 minute to combine dry ingredients
- 40 seconds to melt butter
- 1 minute to combine all ingredients into mug
- 60-80 seconds to microwave
Do You Put Egg in a Mug Cake?
No, you shouldn’t put egg in a mug cake! This is where that spongy texture comes from. A whole egg is way too much for a single serving of cake, which is why mug cakes that call for an egg end up with a strange texture and egg flavor.
Eggs do two things in a cake: they give it lift and their protein provides structure for the cake. When we skip the egg in a mug cake, we can overcome the lack of lift with baking powder, and we don’t really need structure because this isn’t a cake that’s meant to be sliced and plated.
What You’ll Need

How Do You Make Oreo Crumbs?
You can either chop the Oreo with a knife or place it in a small zip-top bag and pound it with a rolling pin. Kids love to help with this part!
How to Make an Oreo Mug Cake
Because this mug cake is made with butter, the method varies a little bit from mug cakes made with oil. Here’s what you’ll need to do.
Mix the dry ingredients. Whisk the flour, sugar, baking powder, and Oreo in a small bowl.
Warm the remaining ingredients. Combine the butter, milk, and vanilla extract in a 10 to 16 ounce mug. Microwave for 30 to 40 seconds, or until the butter has melted.
Combine the wet and dry ingredients. Add the dry ingredients to the mug and stir to combine.
Microwave the mug cake. Place the mug in your microwave and cook for 60 to 80 seconds at 100% power. The mug cake is done when the top springs back when you gently press it.
Rest, then serve. Let the mug cake cool for a few minutes, then add a dollop of whipped cream and additional Oreos, if desired.
Can I Make This Mug Cake in an Oven?
No, this mug cake was developed for making in a microwave. It simply won’t produce the same results if you make it in an oven.
Tips for Success
Here are some hints and tips for making sure your Oreo mug cake turns out perfect:
- Don’t use a typical coffee mug. This recipe will overflow in a standard 8 ounce mug, so be sure to use one that’s between 10 to 16 ounces.
- Adjust the cooking time as needed. The microwave time depends on the power of your microwave; I have a 950 watt microwave and this Oreo mug cake took 60 seconds to bake through. If your microwave wattage varies, so will the time needed.
- Don’t overcook your mug cake! Once the top feels springy and dry to the touch, it’s done.
I’ve got lots of ideas for mixing things up and putting a different spin on this Oreo mug cake!
- Use a different flavor of Oreo cookie, like mint, dark chocolate, or birthday cake.
- Add sprinkles to the batter for a pop of color.
- Instead of using vanilla whipped cream for the topping, try one of my flavored whipped creams. Chocolate whipped cream, coffee whipped cream, and Neapolitan whipped cream would all be excellent here!
How to Store
Mug cakes are meant to be eaten right away. However, if you have leftovers, you can store them in the fridge for up to 2 days. Be sure to reheat the cake in the microwave to warm it up a bit.
