How to Make Triple Threat Brownies
Step 1: Preheat the Oven
Preheat your oven to 350F (180C). This temperature is essential for achieving that perfect chewy texture.
Step 2: Prepare Your Baking Pan
Lightly grease a 9×13 inch pan. Then line it with parchment paper, leaving an overhang around the sides. Greasing helps the paper stick better. Alternatively, you can simply grease the pan.
Step 3: Make the Cookie Layer
In a mixing bowl:
1. Cream together softened butter, brown sugar, and white sugar until smooth.
2. Add in one egg and one egg yolk along with vanilla extract.
3. Gradually mix in flour and salt until just combined.
4. Fold in chocolate chips gently.
Spread this mixture evenly into the bottom of your prepared pan.
Step 4: Add Oreos
Layer 28 Oreo cookies on top of the cookie mixture. Ensure they’re placed closely together for full coverage.
Step 5: Prepare the Brownie Batter
In another bowl:
1. Melt together cubed butter and dark chocolate in a microwave or double boiler until smooth.
2. Stir in granulated sugar until well combined.
3. Add two eggs one at a time, mixing thoroughly after each addition.
4. Sift in flour, cocoa powder, and salt; mix until just combined.
Pour this brownie batter over the Oreo layer in your pan.
Step 6: Bake
Bake in your preheated oven for about 50 minutes or until a toothpick inserted into the center comes out mostly clean.

How to Serve Triple Threat Brownies
Serving Triple Threat Brownies can elevate your dessert experience. These indulgent treats are perfect for sharing or enjoying solo. Here are some serving suggestions that pair wonderfully with these decadent brownies.
A La Mode
- Serve a warm brownie with a scoop of vanilla ice cream on top for a classic combination. The melting ice cream adds creaminess that complements the rich chocolate flavor.
Whipped Cream Topping
- Add a generous dollop of freshly whipped cream to enhance the brownies’ sweetness. You can also sprinkle some chocolate shavings on top for an extra touch.
Drizzle with Caramel Sauce
- A drizzle of caramel sauce brings a delightful contrast to the chocolate. Heat the caramel slightly for easier drizzling.
Fresh Berries
- Serve alongside fresh strawberries or raspberries. The tartness of the berries balances the sweetness of the brownies beautifully.
Chocolate Ganache
- Pour warm chocolate ganache over each slice for an ultra-chocolatey treat. Allow it to set slightly before serving for a glossy finish.
Nut Topping
- Sprinkle chopped nuts, such as walnuts or pecans, on top for added crunch and flavor. Toasting the nuts beforehand can enhance their taste even more.

How to Perfect Triple Threat Brownies
To achieve the best Triple Threat Brownies, consider these helpful tips for perfecting your baking technique.
-
Use Room Temperature Ingredients: Let your butter and eggs come to room temperature for even mixing and better texture.
-
Don’t Overmix the Batter: Mix just until combined to keep your brownies soft and chewy rather than dense and tough.
-
Chill Your Dough: If time allows, chill your brownie mixture before baking. This helps solidify fats and enhances flavor.
-
Check for Doneness Early: Start checking your brownies about 5 minutes before the recommended baking time. They should be set but still slightly gooey in the center.
Best Side Dishes for Triple Threat Brownies
Pairing side dishes with Triple Threat Brownies can create a memorable dessert experience. Here are some delicious options that complement these rich treats perfectly.
-
Vanilla Ice Cream: A classic choice that provides a creamy contrast to the fudgy texture of brownies.
-
Fresh Fruit Salad: A light and refreshing side that balances out the richness of the brownies with seasonal fruits like berries and melons.
-
Chocolate Milkshake: For chocolate lovers, a thick milkshake is an indulgent pairing that enhances the dessert’s flavors.
-
Coffee or Espresso: The bitterness of coffee offsets the sweetness of brownies, making it an ideal drink choice.
-
Chocolate Chip Cookies: For those who want an extra sweet treat, serving cookies alongside offers varied textures and flavors.
-
Peanut Butter Dip: A creamy dip made from peanut butter and cream cheese adds unique flavor notes that pair well with chocolate desserts.
-
Milk: A tall glass of cold milk is not only nostalgic but also helps balance out the sweetness of these decadent brownies.

Common Mistakes to Avoid
Making Triple Threat Brownies can be a delightful experience, but there are some common mistakes to watch out for.
- Skipping the Greasing Step: Failing to grease your pan can lead to brownies that stick. Always grease and line your pan for easy removal.
- Not Measuring Ingredients Correctly: Using incorrect measurements can ruin the texture. Use a kitchen scale or measuring cups for accuracy.
- Overmixing the Batter: Overmixing can lead to dense brownies. Mix until just combined for a lighter texture.
- Ignoring Baking Time: Each oven is different; relying solely on time may result in undercooked or overcooked brownies. Check with a toothpick for doneness.
- Using Cold Ingredients: Cold butter or eggs can affect how well they combine. Make sure they are at room temperature for optimal mixing.
