Chocolate Marshmellow Cookies

This is an old recipe. I could eat 2 dozen of them and I don't know anyone who doesn't like them.

1 cup sugar
1/2 cup shortening
1/2 cup milk
1/2 cup unsweetened cocoa
1 egg
1/2 tsp soda
2 cups flour
1 tsp vanilla
1/2 cup finely chopped nuts ( I use toasted almonds--or you can leave out the nuts altogether)Marshamallows--halved
Light Chocolate Buttercream frosting**

Cream the sugar and shortening. Add the egg, beat well. Sift the dry ingredients and add to the shortening mixture alternating with the milk. Add the nuts and vanilla. Bake at 350 degrees for 8 minutes (my oven takes longer--so watch them--they're supposed to be soft and brownie-like,not crispy).

Remove from the oven and put 1/2 of a marshmallow--cut side down--on top of each. Return to the oven and rebake until the marshmallow is soft. Remove from oven. Let cool. Frost with the buttercream icing.

** I make my own with cold butter, powdered sugar, a little milk and more unsweetened cocoa powder. Use proportions to your own taste.
