1 teaspoon baking soda
1 Tablespoon baking powder
1 teaspoon salt
1/2 cup milk
Pour 2/3 c. boiling water over 1/2 c. cocoa - add to rest of ingredients.
Drop by quarter-cup spoonfuls onto greased cookie sheet. Bake about 10 minutes until tester comes out clean and top springs back when touched, rotating cookie sheets once during baking. When cakes have cooled, spread filling on half of them; cover with remaining cakes.
3/4 c. Crisco (shortening)
3/4 c. Confectioners' sugar
6 Tablespoons Marshmallow Fluff
1 teaspoon vanilla
Enough milk to help mix in better
Mix all together in small bowl.
