Martha Stewart Chocolate Chip Cookie Recipe

These chocolate chip cookie brownies are a spectacular mash-up of classic chocolate chip cookies and a rich, fudgy brownie. Because no one should ever have to choose between the two.

The only disappointing thing about these chocolate chip cookie brownies? That we didn't discover them sooner. This ingenious mashup of our favorite cookie and classic brownies means you never have to choose between the two again. Amen to that.–Angie Zoobkoff

What's a "brookie"?

A "brookie" is exactly the recipe you're looking at in this moment. (We'll give you a moment to let that settle in.) And it's as easy to make from scratch as homemade chocolate chip cookies and brownies. They simply get brought together. You just have one more bowl to wash afterwards but it's sooooo worth it.

Ingredients

1 stick (4 oz) unsalted butter, room temperature, plus more for the pan
1 3/4 cups unbleached all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon baking powder
3/4 teaspoon kosher salt
1/2 cup packed light brown sugar
1/2 cup granulated sugar
1 large egg, room temperature
1 teaspoon vanilla extract
6 ounces bittersweet chocolate, chopped
For the brownie batter
1 stick (4 oz) unsalted butter, cut into large pieces
6 ounces bittersweet chocolate, coarsely chopped
1 1/2 cups granulated sugar
3 large eggs, room temperature
1/4 cup unsweetened Dutch-process cocoa powder
1/2 teaspoon coarse salt
1/2 cup plus 2 tablespoons unbleached all-purpose flour

Directions

Preheat oven to 350°F (177°C). Butter a 9-by-13-inch (23-by 33-cm) baking pan and line with parchment, leaving a 2-inch (5-cm) overhang on long sides.

In a medium bowl, whisk together the flour, baking soda, baking powder, and salt.

In the bowl of a stand mixer fitted with a paddle attachment on medium-high speed, beat the butter and both sugars until pale and fluffy, about 5 minutes.

Reduce the speed to medium-low and beat in the egg and vanilla.

Reduce the mixer speed to low and gradually add the flour mixture and beat until just incorporated. Stir in the chocolate.

In a medium heatproof bowl set over but not touching a pot of simmering water, melt the butter and chocolate, stirring until smooth.

Remove from the heat and whisk in the granulated sugar. Whisk in the eggs, one at a time, until combined. Whisk in the cocoa powder and salt. Fold in the flour until combined.

Pour the brownie batter into the prepared pan, smoothing the surface and nudging the batter into the corners of your pan with an offset spatula.

Crumble the cookie dough evenly over the batter.

Cover with the parchment-lined foil and bake until just set, 20 to 25 minutes.

Remove the foil and parchment and continue baking until golden brown and a cake tester inserted into the center (avoiding the chocolate chunks) comes out with moist crumbs, 25 to 30 minutes more.

Transfer the pan to a wire rack and let cool completely. Lift the chocolate chip cookie brownies from the pan using the parchment and cut it into 24 squares. (The brownies can be stored in an airtight container at room temperature for up to 3 days.) Originally published February 14, 2020.
