Devil Dogs - cooking recipe

Ingredients

1/2 cup butter
1 cup white sugar
1 egg
2 cups all-purpose flour
1 1/2 teaspoons baking soda
1/2 teaspoon baking powder
1 cup milk
1/2 cup unsweetened cocoa powder
1/2 teaspoon salt
1 teaspoon vanilla extract
1/2 cup milk
2 1/2 tablespoons all-purpose flour
1/2 cup white sugar
1/2 cup shortening
1/2 teaspoon vanilla extract

Preparation

Cream together butter and 1 cup sugar, add egg. Sift together 2 cups flour, cocoa, soda, 1/2 teaspoon salt and baking powder. Add vanilla and milk.
Drop by tablespoon full onto ungreased cookie sheet and bake 7-8 minutes at 425 degrees F (220 degrees C). Cool completely and make sandwiches using following filling.
To Make Filling: Combine 2 1/2 tablespoons flour and 1/2 cup milk and cook until it turns to thick paste. Cool completely.
Cream together the 1/2 cup sugar, 1/4 teaspoon salt, 1/2 cup shortening, and 1/2 teaspoon vanilla. Add cooled paste and beat until fluffy. (This will take awhile and if your paste is not completely cooled it will look curdled. ) I usually double this recipe for the filling.
