Ingredients
Ingredient Notes
- Butter: I use salted butter. The salt in the butter balances out the sweetness and enhances the chocolate flavor. If you use unsalted butter, add a pinch (less than ⅛ teaspoon) of salt.
- Flour: The cocoa powder takes the place of some of the flour so you'll only need to use 2 tablespoons of all-purpose flour.
- Chocolate: Use real chocolate chips or chopped chocolate. You can use milk chocolate, bittersweet, or semi-sweet chocolate chips. I prefer using semi-sweet.
- Unsweetened cocoa powder: This gives the brownie batter a rich cocoa flavor.
- Sugar: Use granulated sugar. Since the recipe calls for using unsweetened cocoa powder, you'll need the sugar. Also, sugar is necessary for creating a softer brownie center.
- Egg yolk: You will only need 1 egg yolk in this recipe. Be sure to save the egg white and see below for ways to use it. The egg yolk helps bind the ingredients together, adds richness, and will provide structure to the brownie.
- Vanilla: For fabulous flavor!
- Oreo cookies: You can use another brand of chocolate sandwich cookies if you'd prefer.

How To Make One Oreo Brownie
See the recipe box below for ingredient amounts and full recipe instructions.
- Place 2 tablespoons of butter in a small microwave-safe bowl. Heat in the microwave until just melted. Set aside.
- Whisk together the sugar, flour, and cocoa powder in a small bowl until thoroughly combined.
- Add the melted butter, egg yolk, and vanilla. Stir with a spoon or a rubber spatula to combine. Do not overmix.
- Fold in the chocolate chips and crumbled Oreo cookies.
- Pour the batter into a lightly buttered ramekin. Spread into an even layer. Top with one additional crumbled cookie and chocolate chips. Bake on the middle rack of your oven for 30 minutes.
- Remove from the oven and let cool for 5 minutes before enjoying.
Expert Tips
- Use good quality chocolate chips. I recommend using brands like Ghirardelli, Guittard, Scharffen Berger. On the more economical end, I think Trader Joe's and Whole Foods' 365 chocolate chips are very good too.
- Use the right ramekin. I use a 10-ounce ramekin, if you use a ramekin that is smaller or larger than the one that is recommended, your brownie will bake differently.
- Do not overmix your brownie batter. This will result in a cakey brownie.
- Be careful not to overbake the brownie. Leaving the brownie in the oven for much longer than the recommended baking time can lead to a dry over-baked brownie. The brownie will continue to firm up as it cools.
Frequently Asked Questions
I'm mentioning it again because it is SO IMPORTANT.
For best results, use a 10-ounce ramekin that measures 4-inches in diameter and is approximately 1 ¾-inches tall. Many ramekins don’t have the size printed on them. Because of this, it can be hard to know exactly how large (or small) yours is. The best way to measure the size of your ramekin is to fill it with water and pour the water into a measuring cup.
You can also use mini loaf pans that also hold about 8 to 10-ounces. If you happen to have smaller ramekins, use those and divide the brownie batter between them.
Be sure to check out our Store page where we feature all of the baking dishes we use in our recipes.
If you'd like to make two, double the ingredients and divide the batter between two 10-ounce ramekins. Keep the baking time the same.
If you'd like to enjoy a part of the brownie and save some for later, store the brownie covered on the counter or in the refrigerator for up to 5 days.
