Ingredients You’ll Need

For the Brownie Layer:

1 cup (2 sticks) unsalted butter, melted
1 cup granulated sugar
¾ cup brown sugar
4 large eggs
1 teaspoon vanilla extract
1 cup all-purpose flour
¾ cup unsweetened cocoa powder
½ teaspoon baking powder
¼ teaspoon salt

For the Cookie Layer:

1 cup (2 sticks) unsalted butter, softened
1 cup brown sugar
½ cup granulated sugar
2 large eggs
2 teaspoons vanilla extract
½ teaspoon baking soda
2 ½ cups all-purpose flour
½ teaspoon salt
1 ½ cups chocolate chips (or chunks)

Optional Toppings:

Additional chocolate chips
Chopped nuts
Sea salt for sprinkling

Step-by-Step Instructions

1. Preheat and Prepare

Preheat your oven to 350°F (175°C).
Line a 9×13-inch sheet pan with parchment paper, allowing some overhang for easy removal.

2. Make the Brownie Layer

In a large bowl, whisk together melted butter, granulated sugar, and brown sugar until smooth.
Add eggs and vanilla, mixing until fully incorporated.
Sift together flour, cocoa powder, baking powder, and salt, then fold into the wet mixture.
Spread the brownie batter evenly into the prepared sheet pan.

3. Make the Cookie Layer

In a separate bowl, cream softened butter with sugars until light and fluffy.
Beat in eggs and vanilla extract until smooth.
Gradually add flour, baking soda, and salt, mixing until just combined.
Fold in chocolate chips.

4. Layer the Cookie Dough

Drop spoonfuls of cookie dough over the brownie batter. You can swirl lightly with a knife for a marbled effect or leave as distinct dollops.

5. Bake the Brookies

Bake in the preheated oven for 30–35 minutes, or until the cookie layer is golden and a toothpick inserted in the brownie section comes out mostly clean (a few crumbs are fine).

6. Cool and Slice

Allow the sheet pan brookies to cool completely in the pan.
Lift out using the parchment overhang and cut into squares or rectangles.
Serve as-is or with a scoop of ice cream for an extra indulgent treat.

Tips for Perfect Sheet Pan Brookies

Room Temperature Ingredients: Ensure butter and eggs are at room temperature for better mixing and texture.
Do Not Overmix: Overmixing the brownie or cookie layers can result in dense texture.
Swirling Option: For a marbled look, use a knife or spatula to swirl the cookie dough into the brownie layer gently.
Check Baking Time: Oven temperatures vary, so start checking at 30 minutes to prevent over-baking.
Cooling is Key: Letting the brookies cool completely ensures cleaner slicing and better structure.

Flavor Variations

Nutty Delight: Add ½ cup chopped walnuts, pecans, or almonds to either layer.
Caramel Swirl: Drop spoonfuls of caramel sauce on top before baking and swirl lightly.
Mint Chocolate: Add mint extract to the brownie layer or fold in mint chocolate chips into the cookie dough.
Peanut Butter Chocolate: Swirl peanut butter into the cookie dough for a rich, nutty flavor.
White Chocolate & Raspberry: Fold white chocolate chips and freeze-dried raspberries into the cookie layer.

These variations allow you to personalize your brookies for different occasions and flavor preferences.

Serving Suggestions

Serve warm with a scoop of vanilla ice cream for a decadent dessert.
Pair with milk, coffee, or hot chocolate for a cozy snack.
Cut into small squares for a party platter or bake sale treats.
Wrap individually for portable lunchbox desserts.

Storage & Make-Ahead Tips

Room Temperature: Store in an airtight container for up to 3 days.
