3 minutes

If you haven't figured it out by now, I am a fan of mug cakes, and for good reason too. Did you know mug cakes are a tasty way to use up stale Oreos? Yes, stale Oreos. Maybe, you fell asleep with the sleeve open. Maybe you forgot you had them in your cupboard. Maybe you live alone and accidentally bought the family-sized pack, and now are finding creative ways to use them. Either way, this recipe was created when I discovered my Oreos were a bit stale from not sealing the sleeve correctly before putting them away.

Who doesn't love Oreos, and is there really any other Oreo than double stuffed? Not in my world, at least, which is why I started making this Oreo mug cake with Oreo frosting (Oreo crumbs in the frosting)! Why waste Oreos, that can be used in a cake? It's super delicious, easy, and sure to kill those late-night chocolate cravings.

Pam cooking Spray

This step is optional but could be considered equally important to the other steps in this recipe. Just like you grease your cake pans before baking, consider greasing your mug. It really does make cleaning up easier, and mug cakes are all about convenience and ease, after all.

To Prep

  • Spray a small amount of your favorite cooking spray into the mug.
  • Using a paper towel, soak up excess oil and spread the oil along the entirety of the inside of the mug.

Here's where the work comes in, but don't worry it's minimal. Make sure not to adjust any of these measurements too drastically to avoid losing the cake-like texture. The right amount of wet to dry ingredients is important to getting the perfect mug cake!


  • Add all dry ingredients to your mug and mix them
  • Make sure there are no major lumps before adding wet ingredients
  • Add all wet ingredients to your mug and mix them
  • Add additional ingredients and fold them in
Dry ingredients
  • 1/4 cup sugar
  • 1/4 cup flour
  • 2 tbsp cocoa powder
  • 1/4 tsp baking powder
  • dash salt
Wet ingredients
  • 1 1/2 tbsp oil or melted butter- I think butter adds more flavor, but canola or coconut oil can be used also
  • 3 tbsp of milk
  • 1/4 tsp of almond extract
Additional ingredients

3 Oreos (put one aside to crush on top of the cake once cooked)

In a little over a minute, you can enjoy this Oreo cake with creamy frosting and crunchy Oreos on top!

Note that cooking times may vary depending on your microwave. If the wattage of your microwave is 1200 like mine is. I recommend 70 to 80 seconds. If you are feeling unsure of the time, watch over it a bit. If your wattage is lower, increase the time. If the wattage is higher, reduce the time. Get to know your microwave to decide the best time for you!


  • Cook for 70 to 80 seconds.
  • Let the mug cake cool about a minute after cooking.
  • Frost, crush up additional Oreo and sprinkle it on top, and enjoy!
Frosting Ingredients
  • 1 crushed Oreo
  • 1/2 tbsp softened butter
  • 3 to 3 1/2 tbsp powdered sugar
  • 1/4 tsp of vanilla
  • 1 tsp of milk

To make the frosting, combine the ingredients and whisk with a hand mixer (I use my whisk attachment but you can use the standard attachments).

  • If you are not a frosting fan, omit it. The cake alone is delicious, or if you really want to amp it up top it with a scoop of Oreo ice cream instead.

Mug cakes are a great alternative to baking (not that I don't love baking).
