Use room temperature ingredients for best texture. Don’t overfill the cookie press to avoid uneven dough pressing. Allow cookies to cool completely before sandwiching to prevent melting the filling. Store cookies in an airtight container at room temperature for up to one week or freeze up to three months. Variations include adding nutmeg or cardamom to the filling, mixing cocoa powder into the dough, or using different extracts. For a gluten-free version, substitute all-purpose flour with a gluten-free blend.
