A cookie, but made into a warm, gooey cake? Sign me up!
Look, when you're snacky (is that a word?), I know it's easy to open a pack of Oreos and go to town. But, with 2 extra minutes and a couple of ingredients you probably already have, you can make a dessert that's dialed up a few notches.
🖤 Why You'll Love This Recipe
- It's crazy easy! Who knew you could have cake in under 5 minutes?!
- You get the best of both worlds. Get a creamy, vanilla-like element and rich chocolate in one bite. If you love cookies and cream ice cream, this is the dessert for you! It has almost a brownie consistency, with a crunchy outside and warm, gooey inside.
- It's single-serve. No need to make a whole dessert when you have a sweet tooth.
🍫 Ingredients
- ⅓ cup chocolate cake mix - This is a great shortcut trick - I like to keep a couple of extra bags of cake mix around for mug cakes!
- ¼ cup milk - Go with whole milk in this - it makes it extra rich.
- 2 tablespoon vegetable oil - Really any oil will work with this, but I prefer vegetable oil because a) it's readily available and b) it gives the batter more structure, making it a little denser.
- 2 Oreo cookies - You'll use both the chocolate outside and the cream filling.
Substitutions & Additions
- Use one of the many flavored Oreos instead of the traditional chocolate cookies. This is so good with the strawberry, toffee, or even birthday cake Oreos.
- You can also change the cake mix flavor to match your Oreo flavor!

☕️ How to Serve
I like to serve my cake topped with either a scoop of vanilla bean ice cream or a big dollop of whipped cream. Add a few crumbles of an extra Oreo for a little bit of a crunch.
You can also get creative with your toppers - fresh fruit (strawberries or raspberries), nuts, or a little bit of chocolate syrup would also be yummy!
No matter what - serve it warm. I don't recommend waiting more than 10-15 minutes to eat this after cooking. It tends to get a little rubbery and just isn't as good once it cools to room temperature.
💡 Useful Tips and Tricks
- Small adjustments in cooking time can change the texture of your mug cake. With my 1100-watt microwave, 60 seconds is just about perfect. Take 10 seconds off to have a gooey, lava-style brownie cake. Add 10 seconds for a more solid, "cakey" cake.
- If you have a turntable-style microwave, place the mug on the outside of the turntable to cook it. Strangely, this keeps the heat in the mug more even, resulting in a perfectly cooked mug cake.
- Make the Oreos even easier to mix by pulsing the cookie in the food processor or blender before mixing into the butter & milk.
- For easy clean-up, give your mug a light coat of cooking spray before making the cake.
- I prefer to mix mug cakes with a fork; it makes it much easier to get all of those cake mix pockets evenly mixed into the batter.
