Ingredients You’ll Need

Tip: You’ll find the full list of ingredients and measurements in the recipe card below.

This recipe involves two parts: a cookie dough layer and a brownie batter layer. Each is made from scratch with straightforward ingredients.

For the Cookie Dough Layer:

⅓ cup (75g) unsalted butter, just melted
⅓ cup (70g) packed dark brown sugar
2 tablespoons (25g) granulated sugar
1 large egg yolk
1 teaspoon (5ml) pure vanilla extract
¾ cup (105g) all-purpose flour
¼ teaspoon baking soda
Heaping ¼ teaspoon salt
½ cup (85g) dark chocolate chips, plus extra for topping

For the Brownie Batter Layer:

5 oz (142g) bittersweet chocolate (70% cocoa), coarsely chopped
6 tablespoons (84g) unsalted butter
2 large eggs, at room temperature
¾ cup (150g) granulated sugar
½ teaspoon pure vanilla extract
¼ teaspoon salt
⅓ cup (50g) all-purpose flour

This combination results in a fudgy brownie base topped with a golden cookie crust loaded with melty chocolate chips.

Let’s Get Started

Let’s bake! You’ll need a square 8×8-inch baking pan, parchment paper, and two mixing bowls.

1. Preheat & Prepare the Pan

Preheat your oven to 350°F (175°C). Line an 8×8-inch square baking pan with parchment paper, leaving a little overhang on the sides for easy removal.

2. Make the Cookie Dough Layer

In a medium bowl, whisk together melted butter, brown sugar, and granulated sugar until smooth and shiny.
Add in the egg yolk and vanilla extract. Mix until combined.
Stir in the flour, baking soda, and salt until a soft dough forms.
Fold in the chocolate chips. Set aside while you prepare the brownie layer.

3. Make the Brownie Batter

In a heatproof bowl over simmering water (double boiler method), melt the chopped bittersweet chocolate and butter together, stirring until smooth. Let it cool slightly.
In a separate large bowl, whisk eggs, granulated sugar, and vanilla until pale and slightly thickened (about 1–2 minutes).
Stir the cooled chocolate mixture into the egg mixture until combined.
Add in salt and flour. Mix just until no streaks of flour remain—don’t overmix.

4. Layer and Bake

Pour the brownie batter into the prepared pan, spreading it evenly with a spatula.
Drop spoonfuls of cookie dough over the brownie layer. Don’t worry about covering the entire surface—the dough will spread as it bakes.
Gently press extra chocolate chips into the top for a gooey finish.
Bake for 25–30 minutes, or until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs.
Cool completely in the pan before slicing into squares.

The key to perfect brookies? Don’t overbake! You want that signature soft brownie texture in the center with chewy cookie edges on top.

Servings and Pairing

This recipe yields about 16 squares, depending on how generously you slice them. Perfect for sharing… or not.

Great Pairings:

Glass of milk – Classic, comforting combo.
Vanilla ice cream – Make it a brookie sundae!
Whipped cream & berries – A light, fruity contrast.
Espresso or coffee – The bitter edge of coffee enhances the sweetness beautifully.

Serve warm for maximum gooeyness, or room temp for neat slicing.

Variations

Want to mix things up? These brookies are flexible!

Peanut Butter Brookies – Swirl peanut butter into the brownie layer before baking.
Double Chocolate – Use milk and white chocolate chips in the cookie dough.
Nutty Brookies – Add chopped walnuts or pecans to either layer.
Salted Brookies – Sprinkle flaky sea salt on top just before baking for a sweet-salty finish.
Gluten-Free – Use a 1:1 gluten-free flour blend for a gluten-free option.

Brookies are one of those desserts where a little creativity goes a long way.

Storage Tips

Brookies store beautifully, making them a great make-ahead treat.

Room Temperature – Keep in an airtight container for up to 4 days.
Refrigerator – Store chilled for up to 1 week, but let them come to room temp before eating.
Freezer – Wrap individually and freeze for up to 2 months. Thaw overnight or reheat in the microwave for 10–15 seconds for a gooey treat.

Pro tip: Slightly warm brookies in the microwave to bring back their fresh-from-the-oven magic.

FAQs

Can I use store-bought cookie dough?

You can, but the homemade dough gives a better texture and flavor that complements the brownie layer.

Do I have to use bittersweet chocolate for the brownies?

Bittersweet chocolate balances the sweetness of the cookie dough. You can substitute with semi-sweet if you prefer a slightly sweeter result.

Can I double the recipe?

Yes, double everything and bake in a 9×13-inch pan. Add 5–10 minutes to the bake time, but check for doneness with a toothpick.

Why do I need to use just the egg yolk in the cookie dough?

Using only the yolk helps the cookie dough stay rich and chewy without spreading too much over the brownie base.

How do I know when they’re done baking?

The top should be golden, the edges set, and the center just slightly jiggly. A toothpick should come out with moist crumbs, not wet batter.

Final Thoughts

Brookies Brownies are the ultimate dessert for indecisive sweet tooths and die-hard chocolate lovers alike. They’re rich, indulgent, and ridiculously satisfying.
