Chill the dough 20–30 minutes if it feels too soft to roll or if your kitchen is warm, which helps cookies hold their shape. Pull the cookies when the centers still look slightly underdone; they firm up as they cool for a softer bite that sandwiches well. For crisper sandwiches, bake an extra minute and avoid milk in the filling. Smooth peanut butter works best; if using natural peanut butter, ensure it’s well-stirred and add an extra tablespoon of flour if the dough seems greasy. Flavor twists include adding 1/2 teaspoon cinnamon to the dough, swapping in chocolate peanut butter for the filling, or rolling the dough in turbinado sugar for crunch. Store assembled cookies in an airtight container at room temperature for up to 3 days, or refrigerate for a firmer filling; freeze unfilled cookies up to 2 months.
