Tips for the Best Oreo Mug Cake

  • Don’t skip the baking powder. While this ingredient is optional, it really helps the mug cake rise properly, resulting in a lighter, fluffier cake.
  • Use a fork to mix. A fork will do the best job in breaking apart any lumps of dry ingredients, giving your final result a smoother texture. 
  • Add water to prevent cracking. Before cooking your Oreo microwave cake, drop one tablespoon of water over the top layer of batter. This added moisture will act as a seal, keeping your mug cake from becoming dry and crusty on the top.
  • Use the right mug shape. Long and skinny mugs aren’t great for mug cakes, as their shape does not allow the batter to cook all the way through. Use a wider, shorter mug for the most evenly cooked results.

Variations for Oreo Mug Cake

  • Use different flavored Oreos. While the chocolate flavor might be the most popular, this recipe would also work great with vanilla, strawberry, or red velvet Oreos. Feel free to get creative with the flavors or customize your Oreo mug cake for holidays!
  • Create an Oreo lava cake. For a fun filling, drop a chocolate truffle or a tablespoon of chocolate into the center of the batter before microwaving. Be sure to only press it into the center, and not any further, so that it does not stick to the bottom of the mug.
  • Make a bigger cake. If you’re using a larger mug (more than 12 ounces), double all of the measurements in this Oreo mug cake recipe. Then, increase the microwave time to 2 minutes and 15 seconds.

Why Is My Mug Cake Not Fluffy?

The most likely culprit is overmixed batter, which can lead to a rubbery texture. Using a fork or small whisk, only mix your mug cake until just combined.

There should be no more lumps of ingredients or dry pockets — any further, and you risk ruining the texture of your Oreo microwave cake.

Are Mug Cakes Supposed To Be Gooey?

Yes and no. Your final product should be moist but not liquidy and falling apart. To tell if your Oreo microwave cake is done, insert a tooth pick into the center.

If it comes out clean, it’s done!  If batter sticks to the toothpick, heat for another 20 seconds and try again.

Why Does My Chocolate Mug Cake Taste Bitter?

For those wondering how to make an Oreo mug cake that isn’t bitter, remember not to use too much baking powder.

Also, be sure not to undermix batter, as lumps of powder can create dry, bitter pockets in your cake.
