- 1/2 cup white sugar (100 grams)

For the Brownie Layer

- 1/4 cup cocoa powder (23 grams)

How to Make Triple Threat Brownies
Step 1: Preheat the Oven
Preheat your oven to 350F (180C). This ensures that your brownies will bake evenly.
Step 2: Prepare Your Baking Pan
Lightly grease a 9×13 inch pan. Line it with parchment paper, leaving an overhang on the sides. This helps with easy removal later. Alternatively, if you prefer, simply greasing the pan will work too.
Step 3: Make the Cookie Dough Base
In a mixing bowl:
1. Cream together softened butter, brown sugar, and white sugar until smooth.
2. Add in one egg, one egg yolk, and vanilla extract; mix until combined.
3. Gradually add flour and salt; stir in chocolate chips until incorporated.
Step 4: Layer with Oreo Cookies
Spread half of the cookie dough mixture evenly in your prepared pan. Place Oreo cookies on top in neat rows.
Step 5: Prepare the Brownie Batter
In another mixing bowl:
1. Melt cubed butter and dark chocolate together until smooth.
2. Stir in granulated sugar followed by two eggs.
3. Mix in flour, cocoa powder, and salt until just combined.
Step 6: Assemble & Bake
Pour brownie batter over the layer of Oreos in your pan. Spread it evenly using a spatula.
Bake in your preheated oven for about 50 minutes or until a toothpick inserted comes out with moist crumbs.
Enjoy your homemade Triple Threat Brownies once they have cooled down!
How to Serve Triple Threat Brownies
Serving Triple Threat Brownies is all about enhancing their rich flavors and indulgent texture. Here are some creative ways to enjoy this decadent dessert.
With Ice Cream
- Vanilla Ice Cream: The classic pairing that complements the chocolate flavors perfectly.
- Mint Chocolate Chip: Add a refreshing twist that contrasts nicely with the fudgy brownies.
- Cookies and Cream: For an extra cookie crunch, serve with this flavor for a delightful treat.
Drizzled with Sauce
- Chocolate Sauce: A warm drizzle adds an extra layer of chocolate goodness.
- Caramel Sauce: Sweet and buttery, caramel sauce elevates the taste to new heights.

- Mini Desserts: Cut them into bite-sized pieces to serve at parties.

How to Perfect Triple Threat Brownies
To ensure your Triple Threat Brownies turn out perfect every time, follow these handy tips.
- Use Room Temperature Ingredients: Allow butter and eggs to sit out before mixing. This helps achieve a smoother batter.
- Don’t Overmix: When combining dry and wet ingredients, mix just until combined. Overmixing can lead to tough brownies.
- Check for Doneness: Use a toothpick to check if they’re done. It should come out with a few moist crumbs, not wet batter.
- Cool Completely: Let the brownies cool in the pan before cutting. This helps them set properly for clean slices.
- Store Properly: Keep leftovers in an airtight container at room temperature for up to 5 days or refrigerate for longer freshness.
Best Side Dishes for Triple Threat Brownies
Pairing side dishes with your Triple Threat Brownies can enhance your dessert experience. Here are some great options:
- Fresh Berries: Strawberries or raspberries add a refreshing burst of flavor that complements the brownies well.
- Chocolate Fondue: Serve alongside melted chocolate for dipping, creating an interactive dessert experience.
- Fruit Salad: A light fruit salad provides a healthy contrast to the rich brownies.
- Cheese Platter: A selection of cheeses can balance out the sweetness while adding savory notes.
- Nut Mix: A crunchy nut mix offers a satisfying texture contrast to gooey brownies.
- Coffee or Espresso: A strong cup of coffee enhances the chocolate flavor and provides a nice caffeine kick.
Common Mistakes to Avoid
When making Triple Threat Brownies, avoid these common pitfalls to ensure your dessert turns out perfect every time.
- Ignoring ingredient temperature: Using cold butter or eggs can affect the texture of your brownies. Always bring them to room temperature before mixing.
- Overmixing the batter: This can lead to dense brownies. Mix just until combined for a light and fudgy texture.
- Not measuring ingredients accurately: Baking is a science! Use a kitchen scale or measuring cups for precision to avoid dry or overly wet brownies.
- Skipping the parchment paper: Without it, your brownies may stick to the pan. Always line your baking dish for easy removal.
- Underbaking or overbaking: Keep an eye on your brownies in the oven. They should be set around the edges but slightly gooey in the center for that perfect fudgy bite.

Storage & Reheating Instructions
Refrigerator Storage
- Store in an airtight container for up to 5 days.
- Keep layers separated with parchment paper to prevent sticking.
Freezing Triple Threat Brownies
- Wrap each brownie slice individually in plastic wrap.
- Place them in a freezer-safe container for up to 3 months.
Reheating Triple Threat Brownies
- Oven: Preheat to 350F (180C) and warm for about 10 minutes. This restores their gooey texture.
- Microwave: Heat one slice at a time on medium power for 15-20 seconds. Watch closely to avoid overheating.
- Stovetop: Place in a skillet over low heat, covering with a lid until warmed through.
