Brown Sugar Shortbread

This is one of my favorite recipes. It's super easy to make, and it makes the place smell divine. And with six ingredients, how can you go wrong?

Ingredients:
1 cup unsalted butter, softened
1 cup firmly packed dark brown sugar
2 cups flour
¼ tsp. salt
1 Tbsp. granulated sugar
1 tsp. ground cinnamon

Directions:
Preheat oven to 325F. Spray 9-inch fluted tart pan or 8-inch square baking pan with nonstick spray.

Beat the butter and brown sugar together in large bowl until fluffy, about 3-4 minutes. Add flour and salt. Beat on low speed until dough just comes together. Do not overmix. Spread dough into prepared pan, pressing dough to the edges.

Combine granulated sugar and cinnamon. Sprinkle on top of dough.

Bake at 325F for about 50 minutes, until firm on edges but still soft in the center. Let cool completely on a wire rack, then cut into wedges or squares.
