Refrigerate the dough mixture for 15-30 minutes before scooping to prevent excessive spreading and achieve that signature chewy texture with a crackled powdered sugar exterior.

Gently fold ingredients together just until combined—overmixing develops gluten and creates tough, cake-like cookies instead of the desired chewy, brownie-like interior.

Let Cool Whip sit at room temperature for 10 minutes before mixing so it blends smoothly with other ingredients without creating lumps or deflating the mixture.

Roll dough balls in powdered sugar twice—once before chilling and again just before baking—to create the beautiful crackled shell that enhances both appearance and texture.

Pull cookies from the oven when the centers still look slightly underdone (they'll continue cooking on the hot baking sheet), resulting in perfectly chewy cookies rather than cake-like ones.
