Preheat the Oven and Prepare Baking Sheets

Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone baking mats.

Melt the Chocolate and Butter

In a microwave-safe bowl or using a double boiler, melt the chocolate chips and butter together. Stir until smooth and let it cool slightly.

Mix the Sugars, Eggs, and Vanilla

In a large mixing bowl, beat the granulated sugar, brown sugar, eggs, and vanilla extract until the mixture is thick and slightly lighter in color, about 2-3 minutes. This creates a crackly top on the cookies.

Combine the Chocolate Mixture

Pour the slightly cooled chocolate mixture into the sugar mixture and beat until well combined.

Add the Dry Ingredients

In a separate bowl, whisk together the flour, cocoa powder, baking powder, and salt. Gently fold the dry ingredients into the wet ingredients until just combined. Be careful not to overmix.

Fold in Extra Chocolate Chips (Optional)

For an extra burst of chocolate, fold in additional chocolate chips.

Scoop and Shape the Cookies

Drop rounded tablespoons of cookie dough onto the prepared baking sheets, spacing them about 2 inches apart.

Bake the Cookies

Bake the cookies for 8-10 minutes, or until the edges are set but the centers still look slightly soft. This ensures a chewy, brownie-like texture.

Cool and Serve

Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to a cooling rack to cool completely.
