Save I had one of those nights at 11 PM where the kitchen felt too far away but the sweet tooth craving wouldn't quit. My roommate walked in holding a mug and told me I needed to see what happened when you crushed Oreos into paste. Five minutes later I was sitting on the counter watching this ridiculous simple cake puff up in the microwave like magic. Now it's the kind of emergency dessert I can make with my eyes closed.
Last winter my cousin stayed over and we ended up making six of these in a row testing every combination we could think of. Peanut butter Oreos became an obsession. There's something so satisfying about crushing cookies into batter and watching it transform in the microwave. The whole house smelled like chocolate and we stayed up way too late eating warm cake straight from mugs.
Ingredients
- 4 Oreo cookies: These create the perfect chocolate base since they're already designed to be eaten with milk
- 3 tablespoons milk: Whole milk gives the richest result but any milk works perfectly fine
- 1/4 teaspoon baking powder: This tiny pinch makes a huge difference in texture
- 1 teaspoon sugar: Only if you want it sweeter which sometimes you absolutely do
- 1 tablespoon chocolate chips: They melt into little puddles of gooey perfection
Instructions
- Crush those cookies:
- Place the Oreos in a microwave safe mug and crush them with a fork until they're fine crumbs
- Add the milk:
- Pour in the milk and stir until you have a smooth thick batter
- Boost the batter:
- Stir in baking powder and sugar if you're using them
- Add extras:
- Fold in chocolate chips if you want those gooey pockets
- Magic time:
- Microwave on high for 1 to 1.5 minutes until risen and set but still slightly moist in the center
- Patience pays:
- Let it cool for 1 minute then add whatever toppings make you happy
Pin it This became my go to during finals week when I needed something warm and fast. My friends would text me from their dorms asking if I was making mug cakes again. There's something so comforting about having a freshly baked chocolate cake in minutes.
Making It Your Own
The beauty of this recipe is how easily it adapts to whatever you're craving. Different cookie flavors change everything. Mint Oreos make it taste like thin mint pie. Peanut butter Oreos create this nutty richness. Double Stuf gives you an even creamier texture. I've even used golden Oreos for a vanilla version that's surprisingly good.
Topping Ideas
Sometimes I go all out and sometimes I keep it simple. A scoop of vanilla ice cream melting over the warm cake is pretty hard to beat. Peanut butter drizzled on top creates this salty sweet situation. Nutella heats up beautifully and gets all gooey. Even just a dusting of powdered sugar makes it feel fancy.
Common Mistakes
The biggest error I see people make is not crushing the cookies finely enough. You want actual crumbs not chunks. Also don't use a huge mug or the batter spreads too thin and cooks unevenly. And please trust me on the cooking time.
- Check at 1 minute even if it looks underdone
- Use a standard sized mug not a bowl
- Crush the cookies into fine crumbs
