Brown your salted butter before mixing to add a rich, nutty complexity that elevates the peanut butter flavor and creates more caramelized edges on your cookies.

Refrigerate your dough for at least 30 minutes before baking to prevent spreading, ensuring thicker, chewier cookies with better peanut butter and chocolate chip distribution.

Lightly toast the Reese's Pieces in a dry pan for 1-2 minutes before folding in to intensify their candy flavor and prevent them from sinking to the bottom during baking.

Remove cookies when edges are set but centers still look slightly underdone—they'll continue cooking on the hot baking sheet, resulting in perfectly soft and chewy interiors.

Bring peanut butter to room temperature and cream it thoroughly with butter to ensure even distribution of flavor and a uniform cookie texture throughout the batch.
