What is the white stuff in oatmeal cream pie?

The white stuff—aka the magic inside—is a sweet vanilla buttercream or marshmallow-style filling. In most homemade versions of the oatmeal cream pie recipe , it’s made with butter, powdered sugar, vanilla, and milk or cream. Some commercial varieties might use shortening or corn syrup, but going the homemade route gives you full control over the ingredients. Plus, it tastes way better fresh!

Where did the oatmeal cream pie come from?

The oatmeal cream pie recipe has roots in Southern baking, but it rose to fame thanks to the Little Debbie brand in 1960. This treat was the first snack ever produced by the company and quickly became a nationwide favorite. The idea was simple yet genius—take two soft oatmeal cookies and sandwich them with fluffy cream. A legend was born!

How long does it take for oatmeal cream pies to go bad?

Homemade oatmeal cream pies are best eaten within 2 to 3 days at room temperature if kept in an airtight container. You can stretch that to about 5 to 7 days in the fridge. Just let them sit out for 15–30 minutes before eating so the cream softens up again. Want to keep them longer? Freeze them! They’ll stay good for up to 2 months. Just wrap each one tightly in plastic and store them in a freezer bag.

Why are oatmeal creme pies so good?

There’s something magical about the contrast—chewy oats with smooth, sweet filling. The spices in the cookie (like cinnamon and molasses) blend beautifully with the soft buttercream. Every bite hits that sweet spot between texture and flavor. Plus, let’s be honest—they’re nostalgic. The oatmeal cream pie recipe reminds many of us of childhood, lunchboxes, and simpler times. Comfort food at its finest!

What is America's favorite pie?

While apple pie wears the crown for America’s most iconic pie, the oatmeal cream pie has carved out its own space as a favorite snack cake or dessert sandwich. It’s not technically a traditional pie, but it delivers all the feels of a classic comfort dessert—with oats, cream, and a touch of sweetness in every bite.

What is the oldest Little Debbie snack?

The oatmeal creme pie is actually the oldest and very first snack produced by Little Debbie back in 1960. It set the tone for everything that followed—Swiss Rolls, Nutty Bars, and more. But many still say the original is the best, and that’s why recreating this oatmeal cream pie recipe at home is such a win. It’s tradition in a cookie sandwich!
