These classic homemade thumbprint cookies feature a buttery dough filled with sweet, fruity jam, perfect for any occasion and easy to make.
Chilling the dough before shaping prevents spreading and keeps the thumbprint shape. Use room temperature egg yolk for smooth dough. Press thumbprints gently to avoid jam leakage. Check baking time closely to keep centers soft. Dough can be prepared a day ahead. For dairy-free, use plant-based margarine; for gluten-free, substitute with almond flour but chill longer.
