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.

🙋🏻‍♀️ FAQs

Even though there's not really a standard size for coffee mugs, most average-sized mugs should work. They are typically 12-16 ounces in size. This recipe only fills maybe half of a standard coffee mug. You can also make this recipe in ramekins that are at least 8 ounces.

I wouldn't prepare the cake further than 30-45 minutes out from serving. It tends to get rubbery as it sits. However, you can make the batter in larger batches and refrigerate for up to 48 hours if needed.

I see a lot of mug cake recipes with either baking powder or baking soda. Here's a secret: you don't need it! Your cake will not be as light or airy, but it will have a richer, more pudding-like consistency. So it all depends on personal preference. I prefer the more gooey mug cake, so I omit it.
