Ingredients for 2 ingredient oreo mug cake
Two core ingredients plus optional extras for customization—this mug cake delivers restaurant-quality dessert in minutes.
| Ingredient | Amount | Notes |
|---|---|---|
| Oreos (Original Flavor) 🍪 | 1 ½ oz | Crushed into fine powder |
| Unsalted Butter 🧈 | 2 tbsp | Melted, full-fat preferred |
| Microwave-Safe Mug 🍵 | 1 whole | 12-16 oz capacity |
| Whole Milk 🥛 | 1 tbsp | Optional for creamier texture |
| Vanilla Extract 🌸 | ¼ tsp | Pure vanilla preferred |
| Chocolate Chips 🍫 | 1 tbsp | Semi-sweet, optional topping |
Oreos are the star here—original flavor works best for that classic taste, but double-stuffed adds extra richness. Grab the 14.3 oz package from any grocery store; it’s the standard size for baking. The butter? Full-fat is non-negotiable—it creates that melt-in-your-mouth texture. If you’re using salted butter, reduce the salt in your recipe by half. For the mug, any microwave-safe ceramic or glass mug in the 12-16 oz range works—check your kitchen for one you already own before buying new.
No milk? Skip it or use water—the cake will still be delicious. Want more vanilla flavor? Double the extract, but don’t exceed 0.5 tsp or it’ll taste artificial. Chocolate chips are optional but highly recommended—they add pockets of gooey goodness. For a healthier twist, swap half the Oreos for whole-grain Oreos or add 1 tbsp of almond flour to the mix. The key is crushing the Oreos finely—a ziplock bag and rolling pin work perfectly for this.
This cake is best eaten immediately, but you can microwave it for 10-15 seconds to reheat if needed. Store any leftovers (if there are any!) in an airtight container for up to 3 days in the fridge, though honestly, it’s that good you’ll probably eat it fresh. For meal prep, make a double batch and freeze individual mug cakes in parchment-lined containers for up to 1 month—just microwave from frozen, adding 10 seconds to the cooking time.
Why You’ll Love This Recipe
- No Mixing Needed: I swear, this is the only cake I make that doesn’t require a bowl or whisk. Just mash Oreos, melt butter, stir—boom. That’s it. The microwave does all the heavy lifting while I’m scrolling through my phone or waiting for coffee.
- Rich Chocolate Bliss: Honestly, the flavor punches way above its ingredients. Crumbled Oreos give that perfect crunchy-creamy contrast, and the milk soaks in just enough to make every bite taste like a warm cookie hug. Add a splash of vanilla? Now we’re talking dessert-level satisfaction.
- Crowd-Pleaser Any Day: Between us, this is my go-to for movie nights, last-minute guests, or when I just need a treat without the fuss. Kids love the fun mug presentation, and adults? They’ll ask for seconds before the plate’s even empty. (Yes, even on a Tuesday night.)
- Pantry Staple Magic: I keep Oreos and butter on hand anyway, so this costs me next to nothing. No fancy ingredients, no waste—just pure indulgence. And if I make two? One goes in the fridge for a 30-second reheat later. Zero guilt, all reward.
Step-by-step instructions for 2-Ingredient Oreo mug cake
Here’s the foolproof method for microwave-perfect mug cakes with minimal effort.
Crush the Oreos into Fine Powder
Place the 1.5 oz Oreos (Original Flavor) in a resealable plastic bag and seal tightly. Using a rolling pin or heavy pan, crush the cookies into a fine powder—aim for a consistency similar to flour. You want no visible cookie chunks remaining, as this ensures a smooth, cake-like texture rather than crunchy bits.
If you don’t have a bag, you can crush them directly in a food processor or even by placing them between two sheets of parchment paper and using a heavy book. The finer the powder, the better the texture of your mug cake. I like to sift the crushed cookies through a fine-mesh sieve to remove any lingering crumbs or larger pieces.
Melt the Butter and Mix Wet Ingredients
In a small microwave-safe bowl, melt the 2 tbsp Unsalted Butter in 10-second intervals, stirring between each interval until fully liquid. Butter burns quickly, so keep an eye on it—it should be smooth and just melted, not bubbling vigorously. Once melted, let it cool for 1 minute to prevent scrambling the eggs (if you were adding them) or curdling the milk.
Transfer the melted butter to your microwave-safe mug. Add the 1 tbsp Whole Milk (if using) and 0.25 tsp Vanilla Extract, then stir vigorously with a fork or chopstick until fully combined. The mixture should be homogenous with no streaks of butter remaining. This step ensures even flavor distribution throughout the cake.
Combine Dry and Wet Ingredients
Add the crushed Oreo powder to the mug and stir with a fork until no dry spots remain. The batter will be thick and resemble wet sand—this is normal. If the batter seems too dry, add 1 teaspoon of milk at a time until it reaches a thick but pourable consistency. Overmixing at this stage can develop gluten, so stir just until combined.
Fold in the 1 tbsp Chocolate Chips (if using) with a spoon, ensuring they’re evenly distributed throughout the batter. The chocolate chips will create pockets of gooey goodness in your cake, so don’t worry if they’re not perfectly incorporated. The heat of the microwave will soften them beautifully during cooking.
Microwave to Golden Perfection
Place the mug in the microwave and cook on high power for 60 seconds. Immediately after microwaving, let the cake rest for 1 minute—this allows the heat to distribute evenly and prevents it from cracking or sliding out of the mug when you try to remove it. The edges should be set while the center remains slightly soft and fudgy.
If you prefer a more fully baked cake, microwave for an additional 10-15 seconds, but be careful not to overcook it. The cake should spring back slightly when pressed gently in the center. For a firmer texture, you can microwave for 75 seconds total, but the classic version is best enjoyed with a slightly underdone center that melts in your mouth.
Serve Warm with Optional Toppings
Allow the cake to cool for 2-3 minutes before attempting to remove it from the mug. Run a knife around the edges to loosen it, then invert onto a plate. The cake should release cleanly from the mug, revealing a moist interior with a slightly crisp exterior. Serve immediately while warm for the best texture and flavor.
For an extra touch, drizzle with melted chocolate or a dollop of whipped cream. The contrast of warm cake with cool toppings makes this dessert even more enjoyable. Store any leftovers in an airtight container in the refrigerator for up to 3 days, though I doubt you’ll have any leftovers with this recipe!
Pro Tips For Making 2 Ingredient Oreo Mug Cake
- CRUSH COOKIES FIRST: I learned this the hard way—skipping the crush leaves uneven texture. Use a fork or baggie to smash Oreos into fine crumbs (no big chunks), or they’ll sink like rocks instead of blending smoothly into the batter.
- MELT BUTTER SLOW: Microwave butter in 10-second bursts, stirring between each, until just liquid. Butter burns faster than you think, and scorched butter ruins the whole cake—no amount of milk can fix that.
- DON’T OVERMIX: Stir the batter just until the crumbs are mostly wet. Overmixing makes it gummy and dense. A few lumps? Doesn’t matter—it’ll disappear in the microwave.
- COVER LOOSELY: Use a damp paper towel over the mug instead of plastic wrap. It traps steam for a fluffy rise but lets excess moisture escape—no soggy bottom or dry top. (Yes, even if you’re impatient like me.)
Serving suggestions for this 2 ingredient oreo mug cake
Classic Mug Presentation
Serve your mug cake straight from the mug for a rustic, cozy feel—just run a butter knife around the edges first to loosen it. I like to place a colorful napkin underneath for easy transfer.
For a more elegant touch, use a 12-ounce stoneware mug (like the Le Creuset Stoneware Mug)—it adds warmth to your presentation and makes the cake look even more inviting. 🍵
Topping Ideas
Drizzle melted white chocolate or chocolate ganache over the warm cake for an extra decadent touch. I recommend using Ghirardelli white chocolate squares—they melt smoothly and add a creamy contrast.
For a lighter option, sprinkle crushed peppermint candies or rainbow sprinkles on top while the cake is still warm so they stick.
Pairing Suggestions
This mug cake is perfect with a hot cup of coffee or chai tea—the warmth enhances the chocolate flavors. For a boozy twist, pair it with Baileys Irish Cream or a shot of Kahlúa poured over the cake.
If you prefer non-alcoholic options, vanilla ice cream or whipped cream adds a cool, creamy contrast that’s irresistible. 🥛
Family-Style Serving
Make a double batch in a 16-ounce mug and serve it as a shareable dessert for two. Use a long-handled serving spoon to scoop out portions, and let everyone customize their own with toppings.
This works great for movie nights or when hosting unexpected guests—just double the ingredients and adjust the microwave time to 75-90 seconds.
Kid-Friendly Extras
Turn dessert time into a fun activity by letting kids decorate their own mug cakes. Set out small bowls of sprinkles, mini marshmallows, and crushed Oreos for them to sprinkle on top.
You can also use cookie cutters to shape the cake into fun shapes before microwaving—just press the batter into the cutter before cooking. 🌟
Meal Prep Hack
For a quick breakfast or snack, assemble the mug cake batter the night before and store it in the fridge. When ready to eat, microwave for 70-80 seconds (the batter will be slightly cooler, so add 5-10 seconds).
This is a great way to satisfy sweet cravings without the morning rush. Just remember to add the chocolate chips fresh for the best texture. ⏰

Frequently asked questions
Can I use salted butter instead of unsalted?
Yes, but you may want to reduce the salt in your recipe slightly. Since Oreos already contain salt, using salted butter can make the cake taste overly salty. For best results, use unsalted butter and adjust to taste if needed.
What if I don’t have a microwave-safe mug?
Use any microwave-safe ceramic or glass container that holds 12-16 oz. Avoid metal or dark-colored mugs, as they can cause uneven heating. A standard coffee mug or even a small oven-safe dish works in a pinch. Just check for microwave compatibility first!
Why is my mug cake too dry or crumbly?
This usually happens if the Oreos weren’t crushed fine enough or the batter was overmixed. For a moister cake, add ½ tsp of milk or water to the batter, or try adding 1 tbsp of melted chocolate for extra richness. Stir just until combined to avoid gluten development.
Can I make this mug cake without butter?
Yes! Swap the butter for 2 tbsp of coconut oil (melted) or 2 tbsp of applesauce for a dairy-free version. The texture will be slightly different, but still delicious. If using oil, the cake may be slightly denser, while applesauce keeps it lighter.
How do I make it extra chocolatey?
Add 1 tbsp of cocoa powder to the crushed Oreos for a deeper chocolate flavor. You can also fold in 2 tbsp of chocolate chips or melt 1 oz of dark chocolate into the butter before mixing. For a fudgy center, microwave for 50 seconds instead of 60.
