I, like most people, thrive off inspiration. I look for it during the big events of my life, but also in the everyday happenings around me. I spend most of my days thinking about food and dreaming up new ways to craft ingredients together, and the inspired recipes are always the best ones. My inspiration is derived not just from the big things, like a road trip down the coast or an watching an inspirational speaker, but from the mundane: a trip to the grocery store, a conversation with the cashier at my favorite local coffee shop, the old-school packaging of my favorite childhood treats.

These Peanut Butter Oatmeal Sandwich Cookies with Marshmallow Crème Filling, are also the product of inspiration. They are inspired by the super soft, always nostalgic Little Debbie’s Oatmeal Crème Pie. There’s something undeniably homey and irresistible about biting into that super soft oatmeal cookie, tasting the sweet marshmallow crème, and trying to catch it all as the filling starts to squish out the sides with each bite. They’re a lunch box staple and a decadent treat, but they’re also way more processed than most things I like to eat or serve – so I made them myself.

Although Little Debbie’s is great as-is, in my book, there are few things that can’t benefit from a healthy dose of peanut butter. These cookies are the soft, spiced, pliable cookies that are perfect for squishing together with a bunch of marshmallow cream in the middle, but they also have a nice peanut butter kick and a tender bite from the oats.

The cookies come together quickly, and bake up perfectly soft. These are ones you’re going to want to watch while they’re in the oven though – you want the centers to be barely past dough, and the edges just turning slightly golden brown. Any further and the cookies will lose that soft, squishy texture that makes them so awesome and perfect for sandwiching.

The marshmallow crème filling was hailed as “frosting that should be put on everything” by my friends, if that’s an indication of how good it is. As the one doing the work, I love it too because it’s so simple. Just whip all the ingredients together and voila – done and ready to spread. You get all the marshmallow crème taste without the hassle of making a Swiss buttercream.
