Grandmother's recipe for Thumbprint Cookies that are perfect for showers, weddings, or any other celebration. Perfect for jam, preserves, or fruit curd.
Combine butter and sugar until creamy. Add in vanilla and egg until well-incorporated and then slowly add flour, baking powder, and salt. Shape dough into a ball. Cut into fourths and wrap each section tightly with plastic wrap and store in the refrigerator.
Scoop 1 teaspoon of dough and then roll in between the palms of your hands until a ball, about the size of a walnut, has formed. Drop onto a cookie sheet. Press your thumb into the center of the dough ball to form a slight well. Repeat until all dough has been used.
Place sheet pans in the freezer for about 12 minutes to firm to prevent spreading during baking.
Bake for about 12-15 minutes until brown. Remove from the oven and allow to cool slighty.
Scoop 1/2 teaspoon of your favorite jam, preserves, or fruit curd to fill the center of the cookie.
