Tender and buttery lemon sugar cookies with a silky, tangy lemon curd filling that balances sweet and tart flavors perfectly. Easy to make and perfect for any occasion.
Do not overmix the dough to keep cookies tender. Use softened but not melted butter. Cook lemon curd over low heat with constant stirring to avoid curdling. Chill lemon curd to thicken before assembling. Dust cookies with powdered sugar for an extra special touch. For gluten-free, substitute flour with a 1:1 gluten-free blend containing xanthan gum. Vegan adaptations include using vegan butter and flax eggs.
