Oatmeal Cream Pie Cereal Bars

Oatmeal cream pie cereal bars are made with a combination of Oatmeal Pie Cereal, marshmallows, butter, oatmeal, and cinnamon. They are topped off with a layer of your favorite flavored frosting for a delicious sweet treat.

Little Debbie Oatmeal Cream Pies Cereal Treats

These little cereal bites were created to imitate the Little Debbie prepackaged Oatmeal Cream Pies. You know those ones that you can buy in the vending machines or your kids’ concession stand at the ball game? Kellogg’s has attempted to pack all the flavor from those cream pies into a cereal. Using this cereal will give your cereal bars that crispy oatmeal flavor.


We recommend strengthening the oatmeal flavor by adding a cup of old-fashioned oats to the recipe. This is optional, but if you’re going for that oatmeal flavor, it will be perfect.


You can use large marshmallows or mini marshmallows for this recipe. We don’t recommend using the oversized marshmallows that are made for smores though. Those are more time consuming when cooking, to reach the melted stage.


Using plain salted butter is what we recommend. Other butter substitutes such as margarine or oleo can alter the flavor and their texture when melted is also altered compared to butter.


Cinnamon is optional for the cereal bars. If you like the flavor of baked cinnamon oatmeal or baked oatmeal pies with cinnamon, adding a pinch of cinnamon will help to give your cereal bars that desired boost of flavor that you enjoy.

Vanilla Frosting

You can make homemade vanilla frosting or buy a can of store-bought frosting. Either works well.

Tools You’ll Need:

Mixing Bowl
8×8 or 9×9 pan
Parchment Paper or non-stick spray

Step One: Prep Your Equipment

Prepare your equipment. Making the cereal bars can be a sticky job. To help keep your ingredients from sticking to the mixing bowl and the square pan you’ll pack them into to set up, you’ll want to make a couple of preparations.

Prepare the mixing bowl by spraying it with non-stick cooking spray or by rubbing cooking oil in it. If you’ll be using a spoon or spatula to do the mixing, you’ll also want to grease it. 

The other important step is to prepare the 8×8 or 9×9 pan that you’ll use to form the cereal bars. You can grease the pan or line it with parchment paper and then grease the parchment paper. This will help with ease of removing the cereal bars from the pan when you’re ready to cut them.

Step Two: Melt the Butter and Marshmallows

Melt the butter over low heat, so that it doesn’t burn. Once the butter is melted, you can add the marshmallows to the saucepan. Stir them until they’re completely melted.

Step Three: Mix Everything Together

In this step you can add the marshmallow mixture to the cereal mixture in the mixing bowl and mix everything together. It’s important to mix it all until the marshmallow is completely covering the cereal.

Step Four: Spread into Pan and Top with Frosting

Spread the cereal bar mixture into the greased pan or pan lined with greased parchment paper. It’s important to let the cereal bars cool completely before adding the frosting or the frosting will melt. Once cooled, spread the frosting, and allow the bars to set for about an hour before removing them from the pan and cutting them.
