🍪 What is an Oreo Mug Cake?
An Oreo Mug Cake is exactly what it sounds like—a soft, fluffy cake made in a mug using crushed Oreo cookies as the base. When combined with milk and microwaved, the cookies break down and transform into a sponge-like texture similar to traditional cake.
With just two ingredients (or a few more if you want to level it up), you get a rich, chocolatey dessert that tastes like warm Oreo heaven.
🧾 Ingredients
Basic 2-Ingredient Version:
- 4–6 Oreo cookies
- 3–4 tablespoons milk (dairy or non-dairy)
Optional Add-Ins to Elevate Your Mug Cake:
- ¼ tsp baking powder (for extra fluffiness)
- 1 tsp sugar (if you like it a bit sweeter)
- 1 tsp cocoa powder (for a deeper chocolate flavor)
- Mini chocolate chips, crushed nuts, or marshmallows (for texture)
- A scoop of ice cream or whipped cream on top
👩🍳 How to Make an Oreo Mug Cake
🔸 Step 1: Crush the Oreos
Place 4–6 Oreos into a microwave-safe mug. Use a fork or spoon to crush them into small crumbs. You can also place them in a zip-top bag and crush with a rolling pin first for finer texture.
🔸 Step 2: Add Milk
Pour in 3–4 tablespoons of milk and stir until you get a thick, cake-like batter. The amount of milk may vary depending on how many Oreos you use and how moist you want the cake.
Pro Tip: Stir well to break down the cookie cream—it adds moisture and richness to the batter.
🔸 Step 3: Optional Add-ins
Mix in a pinch of baking powder or cocoa powder for extra rise and depth. Stir in chocolate chips if you’re feeling extra indulgent.
🔸 Step 4: Microwave
Microwave on high for 60–90 seconds. Cooking time depends on your microwave’s wattage. Start with 60 seconds and add 10-second intervals if needed. The top should look set and spring back lightly when touched.
Don’t overcook—it can dry out quickly. It’s better to undercook slightly and let it finish setting as it cools.
🔸 Step 5: Cool Slightly & Serve
Let the mug cake cool for 1–2 minutes (it will be very hot!). Top with whipped cream, ice cream, or even an extra Oreo crumble.
