Toast the salted butter until it turns golden brown before mixing—this adds a rich, nutty depth that complements the peanut butter and chocolate flavors perfectly.

Briefly toast the roasted peanuts in a dry skillet for 2-3 minutes to intensify their natural flavors and add a deeper, more complex taste to your cookies.

Refrigerate your cookie dough for at least 30 minutes before baking to prevent spreading and create that signature chewy, fudgy texture throughout.

The cornstarch in this recipe is crucial—it inhibits gluten development and ensures tender, cake-like cookies rather than tough, spreads-too-much ones.

Remove cookies from the oven when the edges are set but the centers still look slightly underdone—they'll continue cooking on the baking sheet and stay perfectly chewy.
