Perfect Thumbprint Cookies Recipes

Steps:

• Preheat oven to 300 degrees F. Grease cookie sheets.
• Separate egg, reserving egg white. Cream butter or margarine, sugar, and egg yolk.
• Add vanilla, flour and salt, mixing well.
• Shape dough into balls. Roll in egg white, then walnuts. Place on cookie sheets about 2 inches apart. Bake for 5 minutes.
• Remove cookies from oven. With thumb, dent each cookie. Put jelly or preserves in each thumbprint. Bake for another 8 minutes.

Steps:

• Preheat oven to 325 degrees. With an electric mixer on medium speed, beat butter and 1/2 cup sugar until light and fluffy, about 3 minutes. Add egg yolk and vanilla; beat well. In a separate bowl, whisk together flour and salt; add to butter mixture, beating on low until combined.
• Combine ground almonds with remaining 2 tablespoons sugar in a small bowl. Form dough into 1-inch balls, and dip in beaten egg white, then in almond-and-sugar mixture. Make a deep indentation in the center of each ball with your finger or a wooden spoon. Place 1 inch apart on parchment-lined baking sheets.
• Bake 10 minutes, remove from oven, and press down the centers again. Rotate sheets, and bake until golden brown, 8 to 10 minutes more. Transfer sheets to a wire rack to cool slightly. Fill center of each cookie with about 1 teaspoon jam. Let cool completely. Thumbprints can be stored at room temperature in an airtight container, between parchment, up to 1 day (or 3 days, if not filled with jam).
