These heart-shaped Linzer cookies with raspberry jam are buttery, nutty, and filled with tart-sweet jam. They look like they came from a bakery but are surprisingly easy to make at home.
Chill the dough for at least 2 hours, preferably overnight, to prevent spreading. Rechill cut cookies before baking for best shape. Use seedless jam to avoid seeds getting stuck in teeth. For gluten-free, substitute all-purpose flour with a 1-to-1 gluten-free baking flour blend. Unfilled cookies can be stored in an airtight container for up to a week; filled cookies are best within 2-3 days.
