For the best shortbread texture, avoid overmixing once the flour is added and keep the dough on the drier side so it bakes tender and crumbly. If your kitchen is warm, chill shaped cookies for 15 minutes before baking to prevent excessive spread. Use good-quality, not natural separated peanut butter for consistent structure, or if using natural peanut butter, whisk it very smooth and add an extra tablespoon of flour if the dough feels greasy. Mini chocolate chips distribute more evenly, but regular chips work fine. The cookies are done before they look browned; pull them when edges just set. Store airtight at room temperature for up to 5 days or freeze baked cookies for 2 months; thaw uncovered to keep crisp.
