OLD FASHIONED BUTTER COOKIES WITH BUTTER FROSTING

Steps:

• Beat 1 cup softened butter with white sugar in a large bowl until creamy. Beat egg, whole milk, and 1 1/2 teaspoons vanilla extract into butter mixture until smooth. Whisk flour, baking powder, and salt in a separate bowl and gradually stir dry ingredients into moist ingredients to make a smooth dough. Chill dough in refrigerator for 2 to 3 hours.
• Preheat oven to 400 degrees F (200 degrees C). Dust a pastry cloth or kitchen towel generously with flour.
• Divide dough into thirds and roll each third out 1/8-inch thick on the prepared pastry cloth. Cut shapes out of the rolled dough with cookie cutters. Place cookies onto ungreased baking sheets.
• Bake in the preheated oven until cookies are barely browned, 5 to 8 minutes. Let cookies cool on baking sheets for 5 minutes before removing to finish cooling on a wire rack.
• Beat 1 cup softened butter, 3 cups confectioners' sugar, 1 1/2 tablespoons vanilla extract, and evaporated milk in a bowl until smooth. Gradually stir 6 cups confectioners' sugar into mixture until combined. Beat frosting hard until fluffy; stir in additional evaporated milk or confectioners' sugar if needed to reach desired consistency. Frost cooled cookies.
