Oatmeal Cookie Sandwiches Recipe

Cookies:

1. Preheat oven to 350°F (175°C).
2. Whisk together flour, oats, baking soda, baking powder, and salt. Set aside.
3. In a large bowl, beat sugar and Crisco until creamy. Add molasses, eggs, and vanilla, and mix until well combined.
4. Gradually mix in the dry ingredients until a thick dough forms. Fold in walnuts and raisins if using.
5. Scoop 2 tablespoons of dough and roll it into a ball. Place the balls onto ungreased baking sheets, spacing them about 2 inches apart.
6. Bake for 10 to 12 minutes, until edges are lightly browned and centers are set. Cool for 5 minutes, then transfer to a wire rack to cool completely.

Filling:

1. Beat the Crisco in a large bowl until smooth. Add powdered sugar, marshmallow creme, vanilla, and a pinch of salt. Beat until fluffy.

Assembly:

1. Once cookies are completely cool, match them by size. Spoon or pipe a dollop of filling onto the flat side of one cookie and gently press a second cookie on top to form a sandwich.
2. Repeat with the remaining cookies. Chill for 15–20 minutes before serving
