Brown Butter Brookies are the ultimate dessert mashup: classic fudgy brownie layered with chewy brown butter cookie dough, all in one pan. The key twist is browning the butter first — this creates a nutty, almost caramel‑like richness that makes both layers taste even more indulgent. (Maryem Recipes)
They’re perfect for bake sales, family gatherings, or anytime you want a show‑stopping chocolate treat. (Website-Name-Here)

👩🍳 Instructions

1. Brown the Butter:
In a saucepan over medium heat, melt the butter until it foams and turns golden brown with nutty aroma (about 4–5 min). Transfer to a heat‑proof bowl and let cool so it firms slightly. Chilling 30–60 min helps with mixing later. (Maryem Recipes)
2. Make the Brownie Batter:
In a bowl, whisk melted butter, sugar, eggs, and vanilla until smooth. Sift in cocoa, flour, salt, and baking powder. Stir until combined but not overmixed. Set aside. (Website-Name-Here)
3. Prepare the Brown Butter Cookie Dough:
In a mixer, beat cooled browned butter with the brown sugar and granulated sugar until light and fluffy. Add the egg and vanilla. Mix in flour, baking soda, and salt just until combined. Fold in chocolate chips. (Website-Name-Here)
4. Layer It Up:
Preheat oven to 350°F (175°C) and line an 8×8″ pan with parchment. Spread brownie batter evenly on the bottom. Drop spoonfuls of cookie dough over the top — try to cover most of the surface so there’s a marbled effect. (Website-Name-Here)
5. Bake:
Bake 30–35 min, or until the edges are set but the center still looks slightly gooey. A toothpick should come out with moist crumbs, not batter. (Website-Name-Here)
6. Cool & Slice:
Let cool completely in the pan before slicing into squares. For cleaner cuts, chill in the refrigerator 1 hr first. (Website-Name-Here)
