Oatmeal M&M Cookie Cream Pies. Chewy oatmeal cookies sprinkled with a generous amount of mini M&Ms and sandwiched between creamy marshmallow filling.

M&M cookies + oatmeal cream pies = perfection!

Growing up, we were quite literally obsessed with oatmeal cream pies. The days we would open up our lunch box and see an oatmeal cream pie for dessert, meant that it was going to be a good lunch day. LOL.

Leaning into the nostalgia of the OG oatmeal cream pie, we wanted to elevate it a bit. By elevate, we mean add mini M&Ms. But trust us on this one…it takes it to a whole other level. You’ll understand when you take the first bite!

They are the perfect summer treat, weekend dessert or girls movie night treat.

Recipe Q & A

What is the cream in the oatmeal cream pie made of?

In our oatmeal cream pie, we use a creamy marshmallow filling that’s made of three ingredients:

• Softened butter
• Marshmallow Cream
• Powdered Sugar

The marshmallow cream helps to give the filling a light and fluffy texture.

Are homemade cream pies better?

Whether one is better than the other is a matter of opinion. However, in our opinion, these Oatmeal M&M Cookie Cream Pies are far better than the store-bought version. They are the perfect combination of a chewy cookie and a fluffy cream filling that makes these the supreme nostalgic treat.

How can I store the Oatmeal M&M Cookie Cream Pies?

After baking, we recommend storing the cream pies in an airtight container in the fridge. Store them for up to 3 days in your fridge (if they last that long).

Pro tip: After eating a few immediately after making them, we like to store these cookie sandwiches in our freezer and have them as a treat. They taste like a cookie ice cream sandwich.

• Tips for storing in freezer: Individually wrap each cookie sandwich in saran wrap and place them in a gallon size freezer bag.
