Chocolate Brookie Bars for 24 Servings

Instructions:

1. Preheat oven to 350°F (175°C) and line a 9x13 inch baking pan with parchment paper, leaving an overhang.
2. Whisk melted butter and sugar until combined, then beat in the eggs and vanilla until the batter is smooth and glossy.
3. Sift in the cocoa powder, flour, and salt; stir just until the white streaks disappear.
4. Fold in the chopped dark chocolate chunks and spread the batter evenly into the bottom of the prepared pan.
5. In a separate bowl, cream together the softened butter, brown sugar, and white sugar until pale and fluffy.
6. Beat in the egg and vanilla.
7. Gradually add the flour, baking soda, and salt, mixing on low speed until a soft dough forms.
8. Fold in the dark chocolate chips.
9. Scoop the cookie dough in dollops over the brownie layer and gently press it down to cover the surface.
10. Bake for 40–45 minutes until the edges have slightly pulled away from the pan and the top is deep golden brown.
11. Cool completely in the pan for at least 1 hour before lifting the bars out via the parchment paper.
