What to love about this Oreo and milk mug cake

- You can make this easy mug cake recipe in minutes.
- You only need a few pantry ingredients to make this cookie in a mug.
Oreo cookie cake recipe ingredients
- Oreo Cookies: I used Double Stuff Oreos for extra creaminess in this recipe, but original Oreos (or any chocolate sandwich cookie) will also work fine.
- Milk: I went with 2% milk since that was in the fridge. Use whatever is in your fridge.
- Granulated sugar, baking powder, all-purpose flour, and unsweetened cocoa powder.
- Kosher salt: I use kosher salt for everything I cook or bake. I love how easy the big crystals are to gather using my fingertips when I need a quick pinch for a recipe.
- Crushed Oreos: I added crushed Oreos as a topping, but feel free to get more creative with other toppings if you prefer…see the list below for ideas.
- Whipped Cream: Add a quick squirt of whipped topping from a can (such as Redi-Whip) to garnish the mug cake before serving it.
Mug cakes are meant to be enjoyed while they are still warm. However, when a mug cake comes out of the microwave, it is PIPING hot so do take care and let it cool for at least a minute or so.
Don’t overcook your mug cake. Removing it from the microwave may look a bit doughy on top, but it will continue to cook a bit after it comes out.
Depending on how your microwave cooks, you may have to adjust the cooking time a bit to get it just right.
A 12-ounce mug works perfectly for making this mug cake recipe.
Your mug should be about one-third full (and never more than half full of mug cake batter) when you prepare to cook it in the microwave.
Once the mug cake is fully cooked, it will fill it by about two-thirds.
Does Oreo mug cake work?
You better believe it! I admit, I was a bit skeptical at first, too.
But what have you got to lose? Other than a few Oreo cookies and a few pantry ingredients?
Do it! You are going to be sooo pleasantly surprised. 🙂
How to make an Oreo mug cake
Use your fingers to crumble four Oreo cookies into a 12-ounce mug. Set the fifth Oreo cookie aside.
Pour the milk into the mug over the cookies. Using a fork, mash the cookies until well blended with the milk, letting them fully dissolve into the milk.
Combine the sugar, flour, cocoa powder, baking powder, and salt in a small bowl.
Add to the Oreo mixture in the mug, gently stirring until all the ingredients are incorporated.
Place the fifth Oreo cookie into the mug (whole), pushing it down into the cake batter until it’s fully covered.
Microwave the mug cake for one minute. Remove the mug cake from the microwave, allowing it to rest for 10 minutes.
Garnish as desired and serve at once while still warm.
Mug cake topping ideas
The sky is the limit when it comes to toppings for mug cakes. If you can dream it, do it!
- Chopped or sliced nuts, such as almonds, pecans, walnuts, pistachios
- Sliced or chopped strawberries and bananas
- Chocolate syrup or caramel ice cream topping
- Toasted coconut
- Chocolate, butterscotch, or peanut butter chips
- Whipped cream or whipped topping
- Ice cream
- Drizzled warm peanut butter
Why do my mug cakes never work?
I’ve experienced a few of those “fails” myself, but I kept trying different ingredients and cooking times until I finally conquered them.
I was thrilled when this Oreo mug cake was so delicious, especially since it’s such a fast and easy recipe.
Why is my mug cake hard?
Generally, this can be due to overcooking the cake in the microwave.
Then, as the mug cake cools, it gets hard. Remember that mug cakes are truly meant to be enjoyed while still warm.
Microwave mug cake safety
Before you reach into the microwave to grab the handle of the mug that contains your cake, do a quick temperature check of the handle first.
Touch the handle before lifting the cup to test if it’s safe. The last thing you want is to drop your mug cake because the handle is blistering hot from the cooking process!
Just because a mug is labeled microwave-safe on the bottom, doesn’t mean the cup itself won’t get HOT when you’re cooking a mug cake, especially regarding the handle of the mug.
This can vary greatly from mug to mug, and I have no explanation as to why.
Are mug cakes safe to eat?
Yep! Mug cakes are perfectly safe to enjoy, especially in a recipe such as this one where there are no eggs to worry about.
If the mug cake recipe you are using calls for eggs, just be sure you cook it long enough that the egg is fully cooked.
Are mug cakes better with milk or water?
You can substitute water if a mug cake recipe calls for milk. It may change the texture of the cake just slightly, but it will still be quite delicious.
If you struggle with lactose intolerance, you can successfully substitute almond, cashew, or oat milk in most mug cake recipes.
The only time you MUST have milk for a mug cake is when you enjoy it – an ice-cold glass of milk is an absolute.
What is a mug cake?
A mug cake is just as it sounds: a cake made in a mug. Mug cakes are single-serve treats with ingredients combined in the mug and then cooked for a few minutes in the microwave.
Talk about quick and super easy to make and enjoy.
One big problem with mug cakes is that they are super dangerous.
You’ll understand what I mean once you realize how fast you can prepare a warm, decadent mug cake. 🙂
Can you bake a mug cake in the oven?
Great question. I have not tried to bake cake batter in mugs in the oven so I cannot advocate that it’s doable.
You can, however, bake your mug cake batter in oven-safe glass or ceramic ramekins.
Though the shape and texture will be a bit different, they will be delicious.
Bake the batter in 12 oz. ramekins, uncovered, on the center oven rack for 12-15 minutes in a 350-degree F. oven or until a toothpick inserted into the center comes out clean.
Garnish as desired and enjoy.
How long will an Oreo mug cake keep?
Mug cakes don’t hold. It’s just a fact, Jack. Plan to eat your mug cakes while they are still warm from cooking.
Many things that cook in the microwave tend to harden and become chewy once they cool – mug cakes are no different.
Enjoy that mug cake straight away!
