Why This Recipe Works
This recipe works because Oreos already contain flour, sugar, cocoa, and fat, which act as the base for the brownie. When combined with milk, the crushed cookies create a batter that mimics traditional cake or brownie mixtures. This is the magic behind the simple Mug Brownie.
Ingredients In My Mug Brownie
- Oreo Cookies - These cookies contain flour, sugar, cocoa, and fat, which act as the structure for the brownie. When crushed and mixed with milk, they form a batter that mimics a traditional cake or brownie mix. You can use any Oreo flavor to change up the taste, making your Mug Brownie unique.
- Milk - Milk adds moisture to the crushed cookies, helping them blend into a smooth batter. It also contributes to the texture, making the brownie soft and fudgy. You can use dairy or plant-based milk, depending on your preference.
Optional: Chocolate sauce can be added on top for extra sweetness.

How To Make Mug Brownies
Crush the Oreos: To make this mug brownie, start by crushing the Oreos into fine crumbs using a food processor or blender. If you don't have one, place the cookies in a zip-lock bag and crush them with a rolling pin until they turn into a fine powder, ready for your Mug Brownie batter.
Mix with Milk: Transfer the crumbs to a small mixing bowl, then add the milk. Stir until the mixture forms a smooth, thick batter with no dry spots, making sure it's perfect for a Mug Brownie.
Transfer to a Mug: Pour the batter into a microwave-safe mug that holds at least 250ml / 8.5fl oz to prevent overflow.
Microwave the Brownie: Microwave on high for 1 minute. Cooking time may vary depending on the wattage of your microwave (this recipe was tested in an 1100W microwave). If the brownie looks too wet, microwave it for another 10-15 seconds.
Let it Cool: Carefully remove the mug from the microwave, as it will be very hot. Let the brownie sit for one minute to firm up before eating. The cooling process ensures your Mug Brownie reaches the right texture.
Optional Topping: If you like extra sweetness, drizzle chocolate sauce on top and enjoy while warm.
