Parmesan Savories with Caramelized Onion Jam
1 cup butter, softened
1/4 cup sugar
2 cups all-purpose flour
1 cup grated parmesan cheese
Heat oven to 350°F. Line baking sheets with parchment paper; set aside.
Combine 1 cup butter and sugar in bowl; beat at medium speed, scraping bowl often until creamy. Add flour and Parmesan cheese. Beat at low speed until well mixed. Mixture may be crumbly.
Shape dough into 1-inch balls. Place, 2 inches apart, onto prepared baking sheets. Make indentation in center of each cookie with thumb or back of spoon. Edges may crack slightly.
Bake 9-11 minutes or until light golden brown around edges. Transfer to cooling rack. Cool completely.
Fill each thumbprint indentation with about 1 teaspoon caramelized onion jam.
