This Crumbl Brownie Batter Cookie copycat tastes like eating actual brownie batter. A gooey chocolate cookie packed with semi-sweet chocolate chips and topped with delectable brownie batter — fudgy, dense, and impossibly easy to make at home.
Preheat oven to 350°F (177°C) and line two baking sheets with parchment for easy removal of oversized cookies.
Cream 1.5 sticks unsalted butter, 2 oz cream cheese, granulated and brown sugars for 3–4 minutes until fluffy; this combo creates the signature Crumbl soft, fudgy texture.
Add eggs and vanilla; mix well. Sift flour, cocoa powder, cornstarch, baking powder, baking soda, and salt; slowly blend into wet mixture until just combined. Stir in chocolate chips for extra gooeyness.
Scoop dough into 8 equal portions (about 4–5 inch diameter and 150g each). Chill dough balls for 1 hour to ensure thick, brownie-like cookies — essential for the Crumbl-style dense center.
Bake chilled cookies for 13–15 minutes; edges should set but centers remain soft and shiny. Let cool on pan 10 minutes for carryover baking, then transfer to wire rack.
For brownie batter topping: Beat 0.5 stick butter, 2 oz cream cheese, powdered sugar, cocoa, vanilla, milk, and salt until creamy, silky, and rich. This topping is what makes these taste like real brownie batter!
Pipe or spoon a generous dollop of brownie batter topping over cooled cookies. Allow 15 minutes for topping to set for best appearance and texture — just like Crumbl’s signature finish.
