Bright and cheerful, these holiday Strawberry Jam Thumbprint cookies are topped with a tangy lemon icing. Easy to make – simply roll, press, fill, and bake. They make a perfect addition to any cookies plate.
1-1/2 cups all-purpose flour
1/2 cup sugar
1/4 teaspoon salt
1-1/2 sticks cold unsalted butter, cut into small cubes
1 large egg yolk
1/2 cup strawberry jam
1 cup confectioners’ sugar
2 tablespoons lemon juice
Whisk together the flour, sugar, and salt in a bowl. Add the butter and blend the mixture until it resembles coarse meal. Stir in the egg yolk and combine the mixture until it forms a soft dough. Wrap in plastic wrap and chill for at least 2 hours or overnight.
Preheat the oven to 350°F. Let the dough soften slightly, then roll level tablespoons into balls and arrange them about 2 inches apart on a parchment-lined baking sheet. Using your thumb, make an indentation in the center of each ball, being careful not to crack the dough. Fill each indentation with about 1/2 teaspoon of strawberry jam and bake the cookies in batches in the middle of the oven for 12 to 15 minutes. Let the cookies cool on the sheets for 2 minutes, transfer them to racks, and let them cool completely.
Combine the confections sugar with the lemon juice to make a thick icing. Use a small piping bag to ice the cookie or drizzle with a fork. Makes 36 cookies.
