Make It
Step 1
Preheat oven to 350° F. Line baking sheets with parchment paper.
Step 2
Combine flour, cinnamon, salt and baking powder in medium bowl; stir well.
Step 3
Beat butter in large mixer bowl until creamy. Beat in sugar until well blended. Beat in egg yolks and let mixer run for 1 minute. Beat in vanilla extract. Gradually beat in flour mixture.
Step 4
Scoop by level tablespoon and roll into balls. Place balls 2 inches apart on prepared baking sheets. With your fingertip or end of a round wooden spoon, make indentation in center of each ball.
Step 5
Bake for 10 minutes or until the bottoms are just barely golden. Cool on baking sheets for 2 minutes; remove to wire racks to cool completely.
Step 6
Place dulce de leche in heavy-duty resealable bag; snip corner from bag and pipe about ½ teaspoon dulce de leche into indentations. Sprinkle with a little sea salt.
After rolling dough into balls, roll in finely chopped nuts or cinnamon-sugar. Proceed with recipe.
