Every year I join a small group of girlfriends for a holiday cookie exchange and, even though cookies are not “real food,” I do still like to participate in this event (in moderation) because it is a fun gathering! We used to bring a bag of cookies for each person, but one year I asked if we could instead bring our cookies on a platter so everyone could take how many they want of each. That meant I’d have the option only to take one, maybe two, of each and also the nut allergy family could skip anything that doesn’t work for them. So, in general, no one would end up with more cookies than they wanted! Plus, it’s easier to put them on a platter versus bagging them up. :)Cookie Exchange spread

Homemade Oatmeal Creme Pies

For this event, I like to make a different cookie recipe every year (just for fun!) and, bonus, that also means I can share it here with you on the blog. I have to credit my friend Holly for the idea to attempt Oatmeal Creme Pies this year. She made a grain-free version of Danielle Walker’s recently and let me try a bite. I was never a big Oatmeal Creme Pie fan myself (at least when it came to the “Little Debbie” boxed version, which is full of so much junk), but this was so GOOD! So I set out to make a regular version with grains, of course, and also a reduced amount of sugar (compared to other sandwich cookie recipes). I am using rule-breaking sugar here since this is a “special treat,” but also with it being homemade, I can control the amount and not over do it!Oatmeal Creme Pies with homemade marshmallow fluff filling

After trying a couple different options, I ended up going with a marshmallow fluff filling for these. I like how it does not squish down when you take a bite and also isn’t as overly sweet as a typical buttercream. I used my marshmallow recipe (that we make for our outdoor movie party at the end of every school year) and just piped it onto the cookies before it started to set into marshmallows. The homemade version is super yummy and SO much better for you than the boxed stuff – enjoy! Piping the filling on Oatmeal Creme Pies

    1. They won’t be too crunchy to begin with, and if you keep them stored at room temp they’ll be even better. – Nicole

  1. Curious to know how the marshmallow filling “sets up after it has been piped onto the cookies. So does this become a chewy oatmeal cookie with a hard marshmallow in between, on day 2?

  2. Off to try these this afternoon- they look delicious! We just learned how to make marshmallows (the corn syrup way), so I’m excited to try these maple syrup ones! We loved the corn syrup marshmallows, but found them almost too sweet to enjoy.
