Ingredients

The following ingredients have 4 Servings
  • 5 cups all-purpose flour
  • 2 ¼ teaspoons baking soda
  • 1 ½ teaspoons fine grain salt
  • 1 ½ teaspoons cinnamon
  • 4 ½ cups light brown sugar
  • 2 ½ cups unsalted butter
  • 6 eggs
  • 3 teaspoons vanilla
  • 6 cups old-fashioned oats
  • 4 cups powdered sugar
  • 2 teaspoons vanilla
  • 1 ½ cups shortening
  • 4 egg whites (beaten to stiff peaks)

Instruction

  • Preheat oven to 350° F.
  • In a medium bowl, combine flour, baking soda, salt and cinnamon.
  • In a large bowl, cream together (beat until well mixed) butter and brown sugar. Add eggs and vanilla. Gradually add to creamed mixture. Stir in oats. Using a cookie scoop, or a spoon, drop dough by rounded spoonfuls onto Silpat lined or lightly greased baking sheet. Bake for 8-11 minutes. Let cool completely before filling.
  • To make filling, combine powdered sugar, vanilla and shortening until creamy. Fold in beaten egg whites. Spread filling between two cookies to create a sandwich. Wrap each cookie individually in plastic wrap, and store cookie sandwiches in the fridge.
