Oreo Mug Cake (3-Ingredients)

This Oreo mug cake is made with just 3 ingredients: Oreo cookies, milk, and baking powder, creating the easiest chocolate dessert you’ll ever make. Ready in about 5 minutes from start to finish, it’s rich, soft, fudgy, and tastes even better topped with vanilla ice cream.

Behind This Oreo Mug Cake Recipe

Have you ever wanted dessert right now but didn’t want to dirty a sink full of dishes or wait for an oven to preheat?

That’s exactly why I love this Oreo mug cake. It feels almost impossible that a handful of Oreo cookies and a splash of milk can transform into an actual cake (I discovered that when I made the easiest cake made from Oreos), but somehow it works every single time. The cookies soften into a thick batter, the baking powder gives it just enough lift, and after a quick trip through the microwave, you have a warm chocolate cake that’s perfect for satisfying a late-night craving.

But the best part… since the batter is simply crushed Oreo cookies and milk, you don’t have to worry about underbaked eggs or raw flour. If you like a gooier, molten-center cake, simply microwave it for a little less time.

Tips From My Kitchen

• Let the Oreos soak first. One minute is all it takes to soften them enough to mash into a smooth batter.
• Prefer a sweeter cake? The finished result yields a lightly sweet cake, but it may not be sweet enough for everyone. A spoonful of sugar can be mixed into the batter if desired.
• Microwave times vary. Start with 60 seconds if you prefer a softer center or cook up to 90 seconds for a fully set cake.
• Add in a whole Oreo. Pressing one cookie halfway into the batter creates a fun surprise in the middle.
• Serve warm. A scoop of vanilla ice cream melts beautifully over the hot cake.
• Try it with Golden Oreos. If you prefer a vanilla vibe, you can use this exact same recipe and swap the chocolate Oreos for the Golden Oreos.

Key Ingredients

With only three main ingredients, it’s hard to believe this simple combination transforms into a warm, fluffy chocolate cake. Here’s what makes each ingredient work:

Oreo Cookies – The cookies become both the flour and the chocolate base of the cake, while the cream filling adds just enough sweetness. Prefer it sweeter? Add a spoonful of sugar to the batter before cooking.

Milk – Softens the cookies into a thick batter that’s easy to mash together.

Baking Powder – Gives the cake just enough rise to be fluffy rather than dense.

Salt (optional) – Just a tiny pinch helps balance the sweetness and brings out the chocolate flavor.

How to Make Oreo Mug Cake

Instant gratification couldn’t be sweeter and easier! Here are the incredibly simple steps to make this delicious treat.

Soften the Oreos

Roughly chop the Oreo cookies into your microwave-safe mug.

Pour the milk over the cookies, making sure to wet as many of the cookie pieces as possible. Let everything sit for about one minute so the cookies have time to soften.

Mash Into a Batter

Using a fork, mash the softened Oreos until they resemble a cake batter.

It’s perfectly fine if there are still small bits of Oreo throughout the mixture, as they add great texture to the finished cake.

Stir in the Baking Powder

Mix in the baking powder along with a small pinch of salt to balance it out.

The batter should be smooth, thick, and evenly combined.

Add a Whole Oreo

For an extra fun surprise, place one whole Oreo flat on top of the batter.

Use your fork to gently press it about halfway into the mug so it bakes into the center of the cake.

Microwave

Microwave for 90 seconds for a fully set cake.

If you prefer a softer, gooier center, microwave for about 60 seconds instead. Since this recipe is simply Oreo cookies and milk, there’s no raw egg or flour to worry about.

Finish and Serve

Top with a scoop of vanilla ice cream and extra crushed Oreo cookies.

Serve immediately while the cake is still warm.

How to Serve & Store Leftovers

This Oreo mug cake is meant to be enjoyed fresh from the microwave while still warm. Top it with vanilla ice cream, whipped cream, chocolate sauce, or extra Oreo crumbs for an even more decadent dessert. Since it’s a single-serving recipe, leftovers typically aren’t necessary, but if needed, cover and refrigerate for up to one day before reheating briefly in the microwave.
