These lemon curd thumbprint cookies are a delightful twist on the classic buttery cookies. The dough is made with a combination of butter, sugar, and flour, and then rolled into small balls. Each ball is then indented with a thumbprint and filled with a dollop of tangy lemon curd. The cookies are baked until golden brown and the lemon curd is set. These bite-sized treats are perfect for any occasion and will surely impress your guests.
