We are getting nostalgic today with everyone’s favorite Little Debbie’s treat from childhood…Oatmeal Cream Pies! Soft and chewy oatmeal cookies that are made with molasses and brown sugar, filled with the easiest 3 ingredient marshmallow fluff. Every bite is soft, chewy, and FULL of flavor! It tastes just like the classic treat we all know and love, but somehow even BETTER. Truly perfect nostalgic treat to bake this weekend!

About The Recipe

I think one of my favorite recipes my mom and I get to share on the blog are the ones that are just truly nostalgic. For me, one of my favorite treats as a kid (aside from Ding Dongs and Cosmic Brownies, of course!) were oatmeal cream pies!

No joke, I was the kid who loved oatmeal cookies.

I was a chocoholic, there’s no doubt about that, but nothing made me happier than when my mom baked a fresh batch of Oatmeal Raisin Cookies!

So, whenever I saw a pack of Little Debbie’s Oatmeal Cream Pies in my lunchbox as a kid, I was ecstatic.

Now, we are sharing a homemade version that, dare I say, is better than the original!

When we were developing this recipe, we actually looked up the ingredients in the cookies from the box. Let me just say…there’s a lot of things in them that I can’t even begin to pronounce.

So, we took the easy and pantry staple ingredients to develop our cookie recipe! Butter, eggs, sugar, flour, molasses, oats…all these ingredients create a deliciously soft and chewy cookie that’s packed with flavor!

Honestly, I could just eat a whole batch of these cookies on their own without the filling.

But, let’s be real. Who doesn’t love the marshmallow creme filling? Which is what these cookies are filled with!

Well, it’s technically a meringue, but it’s essentially the same thing as marshmallow fluff.

It’s three ingredients, super easy, and soooo good!

All together, these sandwich cookies take me back to childhood with every bite. Simply a must-bake for this weekend!

What Are Oatmeal Cream Pies?

If you’ve never had an oatmeal cream pie (or oatmeal creme pies)…I’m so sorry. The first thing I should say is that oatmeal cream pies are not actually a pie. It’s a sandwich cookie!

They are a snack/treat commercially produced by Little Debbie’s (Mckee Foods). It consists of two oatmeal molasses cookies stuffed/filled with a fluffy creme filling.

This recipe is our take on the classic treat!

Equipment Needed

Ingredients

(Full ingredient amounts and instructions can be found in the recipe card at the bottom of the post)

For The Cookies:

All-Purpose Flour – Just plain unbleached all-purpose flour gives these cookies the perfect structure.
Baking Powder – Leavening agents are a MUST in baking! This provides just the right amount of lift while baking.
Baking Soda – We added just a dash of baking soda to ensure the perfect texture in these cookies, as molasses is an acidic ingredient.
Salt – A little bit of salt to enhance the flavors and cut some of the sweetness!
Unsalted Butter – We like to use unsalted butter in this recipe to control the amount of salt in the cookies. Though, if all you have is salted butter, you can use it! Just be sure to omit the salt in the recipe.
Brown Sugar – For these cookies, we wanted them to be soft and chewy, which is exactly what this brown sugar does!
Large Eggs – You will need one large egg and one egg white for this recipe.
Molasses – This is what gives these cookies all their flavor!
Vanilla Extract – Everything is better with a splash of vanilla, you know?
Rolled Oats – For these cookies, you will need rolled oats (also known as steel cut oats). Do not use instant oatmeal!

For The Filling:

Egg Whites – Remember to set the eggs needed for this recipe out ahead of time!
Granulated Sugar – Check to make sure there are no lumps in your sugar.
Water – You will need water to make the sugar syrup to cook the egg whites!

How To Make Oatmeal Cream Pies

Step 1: Make the cookie dough

In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

Step 3: Prepare filling

With an electric mixer, beat egg whites to medium peaks.

In a small saucepan, combine sugar and water. Cook and stir over medium low heat until sugar dissolves. Stop stirring and brush down sides of pot with a pastry brush dipped in water. Continue to cook, without stirring, to 246°-250° F. With mixer running, slowly pour sugar mixture into egg white. Continue beating until cool.

Step 4: Fill cookies

Turn half of the cookies upside down. Pipe marshmallow fluff on upside down cookies. Top with other half of cookies.

How To Store

Once assembled, these cookies can be stored in a sealed container and kept in the fridge for 3-5 days. You can also freeze them in a lidded, freezer safe container for about 1 month or so.

If you are making these cookies ahead of time, you can store the cookies in a zip top bag or lidded container and keep them on the counter for 1-2 days, in the fridge for 3 days, or freeze them for up to a month. The italian meringue can also be made ahead of time! Store it in an airtight container in the fridge for up to 2 days.

Expert Tips

Set out the ingredients (butter and eggs) to allow them to come to room temperature before you’re ready to make these cookies.
Remember to scrape down the sides of the mixer bowl!
Do not over-bake the cookies! About 12-14 minutes should be about perfect.
When you’re making the meringue, make sure egg whites are at room temperature. The eggs won’t whip properly if not. Also, be sure that the mixer bowl is free of any dust!
Use a digital thermometer to make sure your candy is the right temperature before adding it to the egg whites.
When adding the candy, be sure to stream it in slowly! Do not add it too fast.
Make sure the cookies are completely cool before filling them.
It’s best to use a piping bag to get the marshmallow fluff onto the cookies.
