These bite-sized cookies capture the nostalgic joy of a pop tart in a wholesome, homemade form. A buttery, tender cookie crust envelops a naturally thickened strawberry chia jam, creating a fun and satisfying treat perfect for snacks or lunchboxes.
Do not skip chilling the dough, as it prevents excessive spreading. Ensure edges are sealed firmly to contain the filling. The cookies are done when edges are lightly golden; centers will firm up as they cool. For gluten-free cookies, use a 1:1 gluten-free baking blend. The filling can be made up to 2 days ahead.
