Fun and Festive Monster Cookie Sandwiches

Ingredients

1 cup unsalted butter, softened
1 cup brown sugar, packed
1/2 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt
3 cups rolled oats
1 cup M&M’s (Halloween-themed colors)
1 cup frosting (store-bought or homemade)
Additional M&M’s for decoration

Instructions

Preheat the Oven: Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
Mix Wet Ingredients: In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy. Add the eggs and vanilla extract, mixing until well combined.
Combine Dry Ingredients: In another bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet mixture, stirring until just combined.
Add Oats and M&M’s: Fold in the rolled oats and Halloween-themed M&M’s until evenly distributed throughout the dough.
Shape Cookies: Use a cookie scoop or tablespoon to drop dough onto the prepared baking sheets, spacing them about 2 inches apart. Flatten slightly with the back of a spoon.
Bake: Bake in the preheated oven for 10-12 minutes, or until the edges are golden and the centers are set. Remove from the oven and let cool on the baking sheets for a few minutes before transferring to a wire rack to cool completely.
Assemble Sandwiches: Once the cookies are completely cooled, spread frosting on the bottom of one cookie and top with another cookie to form a sandwich. Press gently to adhere.
Decorate: Add additional M&M’s around the edges of the frosting for a fun and festive look.
