Ingredients
List of Ingredients
- 1 cup unsalted butter, melted
- 2 cups granulated sugar
- 4 large eggs
- 1 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1 cup unsweetened cocoa powder
- 1/2 teaspoon salt
- 1/2 teaspoon baking powder
- 12 Oreo cookies, halved
Measurement Information
Make sure to use a measuring cup for liquids and solids. A kitchen scale can help for accuracy. For butter, a stick usually equals 1/2 cup.
Ingredient Notes
- Unsalted butter: Use this for better control of salt levels. If you only have salted butter, reduce the added salt to 1/4 teaspoon.
- Granulated sugar: Brown sugar can be used for a richer taste, but it will change the texture slightly.
- Eggs: Large eggs are best. If you're short on eggs, use 1/4 cup of unsweetened applesauce as a substitute for one egg.
- Cocoa powder: Use unsweetened cocoa for a rich chocolate flavor. Dutch-processed cocoa will change the taste and may lighten the color.
- Oreo cookies: Any flavor works great. Try mint Oreos for a fun twist!

Step-by-Step Instructions
Preparation Steps
1. Preheat your oven to 350°F (175°C). This step is key for baking.
2. Grease a 9x13 inch baking pan. Use butter or cooking spray for best results.
3. In a large bowl, mix 1 cup of melted butter with 2 cups of sugar. Whisk until smooth.
4. Add 4 large eggs one at a time, whisking well after each addition.
5. Stir in 1 teaspoon of vanilla extract for a lovely flavor boost.
6. In a separate bowl, sift 1 cup of flour, 1 cup of cocoa powder, 1/2 teaspoon of salt, and 1/2 teaspoon of baking powder. This helps the brownies rise nicely.
7. Slowly mix the dry ingredients into the wet mixture. Use a spatula to fold gently.
Baking Process
8. Pour half of the brownie batter into the prepared pan. Spread it evenly across the bottom.
9. Take 12 Oreo cookies and cut them in half. Place them on top of the brownie layer. Space them evenly for a good taste in every bite.
10. Spoon the remaining brownie batter over the Oreos. Make sure to cover them completely.
11. Bake in the oven for 25 to 30 minutes. Check doneness with a toothpick. It should come out with moist crumbs.
Cooling and Serving Recommendations
12. After baking, remove the brownies from the oven. Let them cool completely in the pan on a wire rack.
13. Once cooled, slice the brownies into squares. For a fun touch, serve warm with vanilla ice cream.
14. Drizzle chocolate sauce on top for extra yum! You can also sprinkle crushed Oreos for a nice look. Enjoy every bite!
Tips & Tricks
Common Mistakes to Avoid
When making Oreo stuffed brownies, avoid these common mistakes:
- Overmixing the batter: This can make brownies tough. Mix just until combined.
- Not measuring ingredients: Use precise measurements for best results.
- Using cold eggs: Cold eggs can affect the batter. Room temperature eggs mix better.
- Not greasing the pan: Failing to grease can lead to stuck brownies. Always grease well.
- Opening the oven too soon: This can cause brownies to sink. Wait until baking time is up.
Expert Tips for Perfect Brownies
To make your brownies perfect, keep these tips in mind:
- Use high-quality cocoa powder: This gives rich chocolate flavor.
- Melt butter slowly: This helps avoid separation and keeps it smooth.
- Let the brownies cool: Cooling helps set the texture. Cut them only when cool.
- Add a pinch of espresso powder: This enhances the chocolate taste.
- Experiment with baking time: Each oven is different. Check for doneness with a toothpick.
How to Ensure Moisture and Texture
Keeping your brownies moist is key. Here’s how:
- Do not overbake: Check for moist crumbs, not wet batter.
- Add an extra egg: This can improve moisture and richness.
- Use melted butter: Melted butter adds moisture and flavor.
- Store with a slice of bread: This keeps brownies soft in storage.
- Use foil or parchment: Line the pan for easy removal and moisture retention.
Pro Tips
- Use Room Temperature Eggs: Using eggs that are at room temperature helps them to incorporate more easily into the batter, creating a smoother mixture and a better texture in your brownies.
- Don’t Overmix the Batter: Gently fold the dry ingredients into the wet ingredients until just combined. Overmixing can lead to dense and tough brownies instead of the desired fudgy texture.
- Check for Doneness Early: Oven temperatures can vary. Start checking for doneness a few minutes before the recommended baking time to ensure you don't overbake the brownies.
- Let Them Cool in the Pan: Allowing the brownies to cool completely in the pan before cutting helps them set properly and makes them easier to slice into neat squares.
Variations
Additional Mix-Ins
You can make these brownies even more exciting! Try adding mix-ins like:
- Chopped nuts (walnuts or pecans)
- Semi-sweet or milk chocolate chips
- White chocolate chunks
- Toffee bits
These additions give new textures and flavors. Just fold them in gently with the batter. This way, you keep the brownies rich and fudgy.
Flavor Variations
Get creative with flavors! You can change the taste of your brownies by adding different ingredients:
- Peppermint extract: Add a teaspoon for a minty twist.
- Peanut butter: Swirl some in before baking for a creamy layer.
- Coffee: Add a teaspoon of instant coffee to enhance the chocolate flavor.
These flavor variations can make your Oreo stuffed brownies unique and fun to share.
Alternative Cookie Options
Want to try something different? You can swap Oreos for other cookies. Here are some ideas:
- Chocolate sandwich cookies: They work great too.
- Ginger snaps: For a spicy kick, use these instead.
- Vanilla wafers: These offer a lighter taste.
Changing the cookie can change the whole brownie experience. Feel free to experiment!
Storage Info
How to Store Leftover Brownies
Store leftover brownies in an airtight container. Keep them at room temperature for up to four days. If you want them to last longer, refrigerate them. Just remember to let them come to room temp before serving, as this helps the flavors shine.
Freezing Instructions
To freeze your brownies, first let them cool completely. Cut them into squares and wrap each piece tightly in plastic wrap. Place the wrapped brownies in a freezer bag. They can last in the freezer for up to three months. When you're ready to enjoy, just take them out and let them thaw at room temperature.
Reheating Tips for Best Results
For the best taste, reheat brownies in the oven. Preheat your oven to 350°F (175°C). Place the brownies on a baking sheet. Heat them for about 10 minutes. This warms them evenly and brings back their fudgy texture. You can also microwave them for about 15-20 seconds for a quick fix. Enjoy your warm, gooey brownies!
FAQs
Can I use different types of cocoa powder?
Yes, you can use different types of cocoa powder. Dutch-processed cocoa gives a smoother taste. Natural cocoa adds more acidity and a stronger chocolate flavor. Both work well, but adjust the sugar if you switch types.
How can I tell when the brownies are done?
You can tell when the brownies are done by using a toothpick. Insert it into the center; if it comes out with moist crumbs, they are ready. If it has wet batter, bake a bit longer.
What's the best way to cut brownies?
The best way to cut brownies is with a sharp knife. First, let them cool completely. Use a ruler to mark even squares. Clean the knife with a damp cloth after each cut for neat edges.
Can I make these brownies ahead of time?
Yes, you can make these brownies ahead of time. Bake them and let them cool completely. Store them in an airtight container at room temperature for up to three days. Enjoy them warm or at room temp!
