Molasses Spice-Lemon Cookies

 I got this recipe from the book "The Perfect Cookie." People at work loved them!

Whisk together in a bowl:
2 cups flour
2 tsp. baking soda
1 tsp. ground cinnamon
1 tsp. ground ginger
3/4 tsp. salt
1/4 tsp. ground cloves

In another bowl whisk together until combined:
12 Tbsp. melted butter (a cube and a half)
1 1/2 cups sugar
1/4 cup molasses
1 large egg

Stir flour mixture into molasses mixture until incorporated. Cover bowl lightly with plastic wrap and refrigerate for one hour. Roll dough into 3/4 inch balls and roll in a small bowl containing 1/2 cup sugar. Bake at 375 degrees for 8-10 minutes, until tops are just beginning to crack. Cool on pans for 5 minutes.

For filling, mix together:
3 Tbsp. softened butter
2 cups powdered sugar
3 Tbsp. lemon juice

Spread a heaping teaspoon or so in between two cookies. Let filling set about an hour before serving.
