Homemade Oatmeal + Marshmallow Creme Pies

by amy on 18 October 2012

y’all, i am so excited to share these cookies with you! as i’ve mentioned before, i’m not the hugest sweets fan – most times, i prefer something savory or salty over a sweet. these homemade oatmeal + marshmallow creme pies, though, brought out a crazy, sweets-lovin’ maniac in me. and everyone i shared them with, now that i think about it. =) they’re incredibly decadent + absolutely wonderful.

the oatmeal cookies themselves are perfect – buttery + soft, with just the slightest hint of crispiness around the edges. they are fantastic just on their own – they’ll be my go-to oatmeal cookie recipe from now on – but they’re even better made into sandwiches with marshmallow buttercream. the marshmallow filling is on the sweeter side, which complements the rich, less-sweet oatmeal cookies in a glorious way. after i made these, i made myself give most of ‘em away because i feared i couldn’t resist eating them in massive quantities. that’s how amazing these are – you gotta try ‘em!

homemade oatmeal + marshmallow creme pies

makes about 20 cookie sandwiches, adapted from bakingdom

ingredients

for the cookies:
1 cup unsalted butter, room temperature
1 cup brown sugar
1/2 cup granulated white sugar
2 eggs
1 teaspoon vanilla extract
2 cups all-purpose flour
1 teaspoon cinnamon
1 teaspoon baking soda
1/2 teaspoon salt
3 cups quick-cooking oats

for the marshmallow creme filling:
6 tablespoons unsalted butter, room temperature
1 cup confectioners’ sugar
3/4 teaspoon vanilla
pinch salt
1 1/4 cups marshmallow creme

directions

first, make the cookies:
preheat oven to 350 degrees. line baking sheet with silpat mats or parchment paper.

in a large bowl, or the bowl of a standing mixer, cream the butter for about 30 seconds, then add both sugars + beat until light + fluffy. add the eggs + vanilla, mix well, + scrape down the sides of the bowl as needed.

in a medium bowl, combine the flour, cinnamon, baking soda, + salt. add the flour to the butter mixture in 3 increments until just combined. stir in the oats until evenly distributed.

drop 2 tablespoons of dough (about the size of a golf ball) onto the pan at a time, about 2 inches apart. bake for 10-12 minutes, until golden. allow to cool on the baking sheet for 2 minutes before transferring to a cooling rack. cool completely before filling with the marshmallow creme.

to make the filling:
in a medium bowl, or a stand mixer fitted with the paddle attachment, cream the butter + sugar together until light + fluffy. add in the vanilla + a pinch of salt. mix in the marshmallow creme + beat until light + fluffy. cover bowl with plastic wrap + chill for 30 minutes. if filling appears too soft, add more sugar as needed (amy’s note: 1 cup of confectioner’s sugar worked perfectly for me)

assemble the sandwiches: place 1 – 2 tablespoons of filling on the bottom of a cookie, then place another cookie, bottom side down, on top. continue until all cookie sandwiches are made.

Oatmeal cookies are my favorite in the fall (I dunno), and these sandwich cookies are perfect!

I’ve always wanted to make these, but could never find an icing without shortening. Thank you for realizing my cookie dream.

I love sandwich cookies! There’s something fabulous about having an excuse to eat two cookies stuffed with frosting :)
