Oatmeal Sandwich Cookies with Maple Buttercream

Chewy oatmeal sandwich cookies with maple buttercream. A sweet, buttery, fluffy maple buttercream fall favorite.

Oatmeal Sandwich Cookies

I know oatmeal cookies are often pushed to the shadows by the ever-popular chocolate chip, but for me, oatmeal cookies have always been a bit special.

I have so many lovely childhood memories attached to them. They were my dad’s favorite cookies. Every harvest we would make batches to be sent to the field in our lunches.

I still remember sitting in the big combine with my dad, watching the grain pour into the tank, and eating oatmeal cookies. Oatmeal cookies will forever bring back memories of my dad and hours spent riding with him during harvest.

Since there are probably about 30 million recipes floating around the internet already for regular oatmeal cookies, I decided to add an extra bit of fall flair by layering them with maple buttercream to make them sandwich cookies.

Besides, sandwich cookies are so much fun to eat! First, you get to eat two cookies at once, and second, you get to eat frosting with them!

Maple Buttercream Frosting

I have no clue why maple is a fall flavor to me when it is actually seasonally available in late winter early/spring. Regardless maple and oatmeal go together so beautifully.

Maple Buttercream frosting could not be easier. Cream together the butter, real maple syrup, and powdered sugar until creamy. Go for the real thing when it comes to maple syrup, avoid flavorings and imitations. You won’t regret it.

Oatmeal Sandwich Cookies with Maple Buttercream

1. In a large bowl, cream butter and white and brown sugar until smooth. Beat in eggs and vanilla. Combine the flour, cinnamon, baking soda, and salt in a separate bowl. Stir the flour mixture into the butter and sugar bowl. Gently stir in rolled oats. Roll the dough into balls and chill for about 30 minutes
2. Preheat the oven to 325°F. Bake the cookies for 10-11 minutes or until lightly browned. Do not overbake. Let cool on the cookie sheets for five minutes and then transfer to a wire rack to cool completely.
3. To make the buttercream, beat the butter with a mixer on high speed for 2-3 minutes. Add the maple syrup and powdered sugar and beat until smooth. To assemble the cookies spread a tablespoon or two of buttercream on the back of a cookie. Top with another cookie. Makes about 10 sandwiches.

Oatmeal Sandwich Cookies

Oatmeal cookies are so nutty and filling. I love that they are not overly sweet, it makes eating them for breakfast justifiable in my book.

Butterscotch Oatmeal Cookies are chewy oatmeal cookies filled with butterscotch chips… aka Oatmeal Scotchies.  A cookie jar favorite, these cookies are a hit with kids and adults.

Chewy, thick, Peanut Butter Oatmeal Cookies with chocolate chips are a treat that we’ve enjoyed for a lot of years now. We love them made into ice cream sandwiches too.

I not-so-humbly declare that these are the best Brown Butter Oatmeal Cookies on the internet. And yes, they have chocolate chips – raisins need not apply.
