What Makes This Recipe Great

Introducing the easiest, most delicious microwavable dessert recipe, Oreo Mug Cake! If you’ve tried my Brownie in a Mug, Chocolate Chip Mug Cookie, or Cinnamon Roll in a Mug, you know that mug desserts are just as delicious as their larger equivalents but so much easier in single serve form! 

As someone who’s been mostly gluten-free for almost 10 years, I was so excited to see gluten-free Oreos at the store recently! They were one of my favorite childhood snacks, and I love that I can enjoy them again occasionally. For this dessert, feel free to use gluten-free or regular Oreos. 

I’ve tried many versions of an Oreo mug cake that only has 2 or 3 ingredients, but I’ve found that they are lacking in terms of flavor or texture. This version has a couple more ingredients, but it’s still so easy and quick with a perfect decadent texture and sweet chocolatey flavor.

Ingredient Notes and Equipment

With a few simple ingredients, this easy dessert will satisfy your sweet tooth in no time! 

• Milk of your choice: I used almond milk, but you can use regular whole milk or any type of dairy or non-dairy milk (soy milk, oat milk, etc.) you have on hand. 
• Oreos: I used gluten free, but you can use any version that you prefer. 
• All-purpose flour: I used gluten free flour, but substitute regular flour if desired. 
• Unsweetened cocoa powder
• Granulated sugar
• Baking powder
• Vanilla extract
• Toppings: Scoop of vanilla ice cream, whipped cream, crushed Oreo crumbs, chocolate chips, peanut butter, chocolate syrup, caramel sauce, fresh berries, and/or sprinkles.
• Microwave-safe Mug: You can use any coffee mug or small ramekin you have, just make sure it’s safe to use in the microwave.

Step-by-Step Instructions

1. Pour milk into a mug or a ramekin. Microwave for 30 seconds until heated through.
2. Add the Oreos to the milk and use a fork or a pestle to crush them up until a smooth, dark mixture is formed.
3. Add flour, cocoa powder, sugar, baking powder, and vanilla extract to the mixture. Stir together until the batter is combined.
4. Microwave for 90 seconds until just set.
5. Cool for 1-2 minutes before adding your favorite toppings and digging into this amazing treat.

Expert Tips

• Microwaving the milk in the first step until it’s hot makes it really easy to crumble up the Oreo cookies, so don’t skip this step.
• Oreos are vegan, so replacing milk with dairy-free milk will make this recipe vegan!
• This recipe works with regular Oreos or gluten-free Oreos.
• Makes 1 individual serving or 2 smaller servings. It’s best enjoyed right away.

Serving Tips

• Serve this delicious dessert topped with a scoop of ice cream, whipped cream, crushed Oreos, chocolate chips, peanut butter, chocolate syrup, caramel sauce, fresh berries, and/or sprinkles.
