Ingredients

• 1/2 cup (1 stick) unsalted butter, at room temperature
• 1 1/2 cups packed dark brown sugar
• 2 eggs
• 1 teaspoon vanilla extract
• 2 1/2 cups all-purpose flour
• 1/2 teaspoon baking powder
• 1 teaspoon baking soda
• 1/4 teaspoon salt
• 1 cup plain low-fat yogurt
• Burnt Butter Icing

Instructions

1. Cream butter and sugar on medium speed until light. Blend in eggs, one at a time, mixing well after each addition. Stir in vanilla.
2. In a separate bowl, whisk together flour, baking powder, baking soda, and salt. Add flour mixture to batter, alternately with yogurt, to make a smooth dough. Cover lightly and refrigerate for 1 hour.
3. Preheat oven to 350 degrees F. Lightly grease or spray cookie sheets.
4. Drop batter by tablespoonfuls onto cookie sheets. With the help of a second spoon, shape cookies into rounded forms.
5. Bake cookies for 15 minutes, or until firm to the touch and golden brown on the bottom. Let stand on cookie sheets for 2 minutes, then remove to wire racks to cool.
6. When cool, lightly frost cookies with Burnt Butter Icing. Let icing set before serving.
