2 1/2 c. flour
1 tsp. baking soda
1/4 tsp. salt
2 sticks unsalted butter at room temperature
3/4 c. store-bought dulce de leche, plus more for filling
3/4 c. brown sugar
1/2 c. sugar
2 large eggs
Preheat oven to 350 degrees F.
- Whisk together the flour, baking soda, and salt.
- Beat the butter at medium speed until soft. Add the 3/4 c. dulce de leche and both sugars and continue to beat until light and fluffy, about 3 minutes. Add the egss one at a time, beating for 1 minute after each addition. Reduce mixer speed to low and add dry ingredients, mixing only until they disappear into the batter.
- Spoon the dough by heaping teaspoonsfuls onto greased cookie sheets; leave 2 inches between scoops.
- Bake for 10-12 minutes. Cookies will still be soft, so let them cool a few minutes on the cookie sheets before removing them. Make sure to cool cookie sheets completely before re-using them.
- When cookies are completely cool, spread the flat bottoms of half of the cookies with reserved dulce de leche, and sandwich with the flat sides of the remaining cookies.
