Molasses Spice Lemon Sandwich Cookies

These cookies are amazing if you are a fan of the old fashioned molasses cookies, which my grandmother used to make (dating them back to at least the 1940's).
This version is jumped up by having a lemon buttercream frosting holding two of them together.
I made these with a #100 scoop, which is about as small as you can go with an easily encountered measuring device (and since they are sandwiches, you want them to be uniform--no one wants to spend oodles of time trying to find two cookies of the same size!  Just make them more or less the same to begin with), so this is more of a cookie to serve as a solo choice than on a plate of multiple cookies.

Cookie:
2 c. flour
2 tsp. baking soda
1 tsp. cinnamon
1 tsp. ginger
1/4 tsp. cloves
1/4 c. molasses
1 1/2 c. sugar
1 egg
12 tbs. butter, melted
pinch of salt

Frosting:
3 Tbs. butter
3 Tbs. lemon juice
2 c. confectionery sugar

1. Whisk flour, baking soda, cinnamon, ginger, cloves, and salt together in a medium bowl.  In a separate bowl mix sugar, molasses, egg, and butter together, then add the dry ingredients in batches, stirring each time until combined.  Chill dough 1 hour.
2. preheat oven to 375 degree.  Make equal sized balls, and roll them in granulated sugar, then bake for about 10 minutes, then cool
3. Make the frosting by whisking butter, lemon juice and confectionery sugar together.  Put enough frosting between two cookies so it can be seen from the edges, but not enough that it squeezes out of the cookie when you bite into it.
