If you’ve got a sweet tooth and five minutes, this oreo mug cake is about to become your new go-to dessert. Made with just a handful of simple ingredients and ready in 90 seconds, it’s soft, fluffy, and packed with nostalgic Oreo flavor. Whether you’re gluten-free, dairy-free, or just craving a quick chocolate fix, this easy dessert has you covered.
Why You’ll Love This Recipe
If you’ve tried my Brownie in a Mug or Gluten-Free Chocolate Chip Cookie in a Mug, you already know mug desserts can be just as satisfying as a full batch — with zero mess or leftovers. This version uses gluten-free Oreos (or regular if you prefer) to create a decadent, rich, single-serving cake with the perfect soft texture.
After experimenting with minimalist, two-ingredient versions, I found they often turned out dense or bland. So this recipe includes just a few extra pantry staples — flour, cocoa powder, and baking powder — to give it a more cake-like structure and flavor. It’s still quick and easy, but way more satisfying.
As someone who’s been mostly gluten-free for years, discovering gluten-free Oreos felt like unlocking a portal to my childhood. This sweet treat brings back all the flavor of dunking Oreos in milk — only now, you get cake at the end.

Ingredients You’ll Need
This simple dessert recipe comes together with just a few pantry basics:
- Milk of your choice: I used almond milk, but oat milk, soy milk, whole milk, or any non-dairy milk works great.
- Oreos: Use classic or gluten-free Oreo cookies depending on your preference.
- Flour: I used gluten-free all-purpose flour; regular flour works too.
- Unsweetened cocoa powder: For a rich chocolate flavor.
- Granulated sugar: Sweetens the batter just enough.
- Baking powder: Helps the cake rise.
- Vanilla extract: Rounds out the flavor.
- Microwave-safe mug or ramekin: Make sure it’s safe for high heat.
- Optional toppings: A scoop of vanilla ice cream, whipped cream, crushed Oreo crumbs, chocolate chips, peanut butter, or even sprinkles. The best part is making it your own.
How to Make Oreo Mug Cake
Step 1: Pour your milk into a microwave-safe mug or ramekin. Microwave for 30 seconds, just until hot.
Step 2: Add the Oreos to the warm milk and use a fork or rolling pin to crush them into a dark, smooth paste.
Step 3: Stir in the flour, cocoa powder, sugar, baking powder, and vanilla until combined.
Step 4: Microwave for 90 seconds, or until the cake is just set but still moist. Let cool for 1–2 minutes. Add your favorite toppings and dig in.
Tips for the Best Oreo Mug Cake
- Heat the milk first. This softens the Oreos and makes them easier to break down into a batter — don’t skip it.
- Microwave strength matters. Every microwave is different, so adjust by ±10 seconds if needed.
- Vegan-friendly option: Use non-dairy milk and plant-based whipped topping. Oreos are accidentally vegan!
- Eat it fresh. This is one of those single serving cakes best enjoyed immediately.
Serving Tips
For the most indulgent experience, top your cake with a cold scoop of ice cream. Add sprinkles, peanut butter, or melted chocolate to make it your own. Craving more crunch? Stir in a few crushed cookies after microwaving.
