The image shows a round cookie divided roughly in half, with one side golden brown and the other side dark chocolate, both sides sprinkled with melted chocolate chips. The cookie sits on a white wire cooling rack over a white marbled surface. The texture of the golden side is slightly crumbly, while the chocolate side is smooth and rich.

Ingredients

3 oz dark chocolate (85g), between 65-75% cocoa
1/2 cup unsalted butter (113g)
1/4 cup Dutch processed cocoa powder (25g)
1 large egg
1 egg yolk
1/2 cup light brown sugar (100g)
1/4 cup granulated sugar (50g)
1/2 tsp vanilla bean paste
1/2 tsp instant coffee dissolved in 1/2 tsp hot water
1 cup all purpose flour (130g)
1/2 tsp baking powder
1/8 tsp baking soda
1/2 tsp salt
4 oz milk chocolate, chopped (113g)
1/2 cup unsalted butter, room temperature (113g)
1/3 cup packed light brown sugar (67g)
1/3 cup granulated sugar (67g)
1 large egg
1 egg yolk
1/2 tsp vanilla bean paste
1/2 tsp instant coffee dissolved in 1/2 tsp hot water
1 1/4 cup all purpose flour (162g)
1/2 tsp salt
1/2 tsp baking powder
1/8 tsp baking soda
4 oz dark chocolate, chopped (113g)

Instructions

Step 1: Make the brownie batter dough by melting the dark chocolate and 1/2 cup butter in a microwave-safe bowl in 15 second increments, stirring until smooth. Stir in the cocoa powder and set aside to cool.
Step 2: In a separate bowl, whisk the egg, egg yolk, light brown sugar, granulated sugar, and vanilla bean paste on high speed for 3-4 minutes until the mixture is light and nearly tripled in volume.
Step 3: Add the cooled chocolate mixture and dissolved coffee to the egg mixture. Whisk on low speed until just combined.
Step 4: Sift in the flour, baking powder, baking soda, and salt. Gently fold in with a rubber spatula until just combined, then fold in the chopped milk chocolate. The batter should be thick but not fully dough-like yet.
Step 5: For the chocolate chip cookie dough, whisk the room temperature butter, granulated sugar, and brown sugar in a large bowl on medium-high speed until fluffy and light in color, about 2-3 minutes.
Step 6: Add the egg, egg yolk, vanilla bean paste, and dissolved instant coffee. Whisk to combine for about 1 minute.
Step 7: In a separate bowl, sift together the flour, baking powder, baking soda, and salt. Add these dry ingredients to the wet mixture in two batches, folding gently with a spatula. Fold in the chopped dark chocolate. Avoid overmixing.
Step 8: If needed, chill the brownie batter for 5 minutes until firm enough to scoop. Similarly, chill the cookie dough for 5-10 minutes if too sticky.
Step 9: Line two baking sheets with parchment paper. Scoop the brownie dough into 1 oz balls on one sheet, and the cookie dough into 1 oz balls on the other.
Step 10: To assemble each brookie, place one cookie dough ball and one brownie dough ball next to each other, alternating until you have six balls. Gently press the balls together and roll into one 6 oz marbled ball. Repeat for 6 brookies.
Step 11: Refrigerate the brookie dough balls overnight or for at least 6 hours.
Step 12: Preheat the oven to 375°F (conventional). Place the chilled dough balls on a parchment-lined cookie sheet, spacing at least 3 inches apart.
Step 13: Bake for 5 minutes at 375°F, then lower the temperature to 340°F and bake for an additional 11-13 minutes, totaling 16-18 minutes. The cookies should be golden and set on the edges but still soft in the center.
Step 14: Remove from oven, sprinkle with flaky sea salt, and optionally add extra chopped chocolate on top. Allow to rest for at least 20 minutes before serving.

Tips & Variations

Use good quality chocolate for the best flavor and fudgy texture.
If your dough is too sticky, chilling it helps make scooping easier and avoids spreading while baking.
For a mocha twist, increase the dissolved instant coffee slightly to enhance depth of flavor.
You can bake any leftover brownie batter separately as small brownie cookies.

Storage

Store the baked brookie cookies in an airtight container at room temperature for up to 4 days. For longer storage, freeze them wrapped tightly for up to 3 months. Reheat gently in a microwave or oven to restore softness.

How to Serve

The image shows a close-up of a cookie with two halves, one side is light brown and the other side is dark chocolate brown. The cookie is round with a slightly rough texture, and both sides are topped with scattered shiny chocolate chips. It sits on a black cooling rack on top of a white marbled surface. Small salt flakes are visible on the dark chocolate side, adding texture contrast. Another cookie is partially visible in the top right corner and bottom right corner, both showing the same two-tone design. Photo taken with an iphone --ar 4:5 --v 7

FAQs

Can I make this recipe without instant coffee?

Yes, the instant coffee is optional and mainly enhances the chocolate flavor. You can omit it if you prefer, but adding at least a small amount helps deepen the taste.

Why does the dough need to chill before baking?

Chilling firms up the dough, making it easier to handle and preventing excessive spreading during baking. It also helps the flavors meld, resulting in a richer cookie.
