How to Make Oatmeal Sandwich Cookies

Ingredients

For the cookies:

1 cup unsalted butter, softened
1 cup brown sugar
1/2 cup granulated sugar
2 large eggs
1 teaspoon vanilla extract
2 cups rolled oats
1 1/2 cups all-purpose flour
1 teaspoon baking soda
1/2 teaspoon salt

For the marshmallow filling:

1/2 cup unsalted butter, softened
1 cup powdered sugar
1 cup marshmallow fluff
1 teaspoon vanilla extract

Directions

Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper.
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until smooth. Beat in the eggs one at a time, then stir in the vanilla.
In another bowl, combine the rolled oats, all-purpose flour, baking soda, and salt. Gradually blend this dry mixture into the creamed mixture until just combined.
Drop rounded tablespoons of dough onto the prepared baking sheets. Bake for 10-12 minutes, or until the cookies are lightly browned. Allow cookies to cool on the baking sheets for a few minutes before transferring to wire racks to cool completely.
While the cookies are cooling, prepare the marshmallow filling by beating together the softened butter, powdered sugar, marshmallow fluff, and vanilla extract until smooth and creamy.
Once the cookies are completely cooled, spread a thick layer of marshmallow filling on the flat side of one cookie, then top with another cookie to create a sandwich.
Serve the cookies with a glass of milk and enjoy!

FAQs

Can I use quick oats instead of rolled oats?
Yes, quick oats will work, but they may change the texture slightly. Rolled oats give a chewier cookie.

How do I make the cookies softer?
To make softer cookies, do not overbake them and try adding an extra egg yolk.

Can I make the cookies ahead of time?
Yes, you can bake the cookies a day in advance. Just store them properly and add the filling when you're ready to serve.
