Ingredients

• 1 teaspoon baking soda
• 1 teaspoon vanilla extract
• 1 teaspoon baking powder
• 2 tablespoons milk
• 2 cups packed brown sugar
• 1 teaspoon ground cinnamon
• 2 cups quick cooking oats
• 2 cups confectioners' sugar
• 2 large eggs
• 3 tablespoons boiling water
• 1 large egg white, beaten
• 0.75 cup shortening
• 0.5 teaspoon salt
• 2.5 cups all-purpose flour
• 0.75 cup unsalted butter, softened

Recipe Instructions

Step 1

Drop spoonfuls of dough 2 inches apart onto the prepared baking sheets.

Step 2

Preheat the oven to 350 degrees F (175 degrees C). Lightly grease 2 baking sheets.

Step 3

Make the cookies: Beat brown sugar and butter in a large bowl with an electric mixer until light and fluffy. Add eggs and mix well.

Step 4

Mix together flour, cinnamon, baking powder, baking soda, and salt in a separate bowl. Add flour mixture to wet ingredients in 2 batches, alternating with boiling water, mixing batter after each addition until well combined. Stir in oats.

Step 5

Bake in the preheated oven for 10 to 12 minutes, switching racks halfway through. Remove from the oven and transfer to wire racks to cool.

Step 6

While the cookies are cooling, make the filling: Beat 1 cup confectioners' sugar, egg white, milk, and vanilla until combined. Beat in shortening and remaining 1 cup confectioners' sugar until light and creamy.

Step 7

Spread filling onto 1/2 of the cooled cookies, then sandwich with remaining cookies.
