These homemade oatmeal pies are even better than any childhood memories you may have of the Little Debbie oatmeal creme pies. Soft oatmeal cookies with a creamy filling that lend themselves to being the type of cookie you never knew you needed in your life until sinking your teeth into them and realizing you’d be hooked forever!

What I love about these cookies is how unassuming they appear to be…innocently delicious without looking overly decadent yet people go crazy over them. I always tend to get requests for my recipe when I’ve brought a batch to a social gathering.

And while I can offer you this incredible recipe, I, unfortunately, can’t offer an explanation as to why they are called “pies” instead of “cookies”. Perhaps it’s because you have two cookies sandwiched with a luxuriously creamy marshmallow filling …who knows?!… Just roll with it and enjoy!

TIPS FOR MAKING HOMEMADE OATMEAL PIES

When choosing your molasses, opt for a milder flavored molasses. The concentrated flavor of blackstrap molasses is a little too intense for these cookies.
Spread your cookie dough out on your baking pan as these cookies tend to spread when baking.
If any of your cookies look out of shape after baking, you can easily reshape them while they are still warm on the pan by using the edge of a knife or spatula.
I recommend that you store these cookies in the freezer or in the refrigerator until serving. They only take a minute or so to soften.

How to Make Homemade Oatmeal Pies

Preheat oven to 350° F.
In a food processor, pulse to grind 1/2 cup of quick-cook oats into a powder.
In a medium bowl, whisk together 1 1/2 cups of quick cook oats, the ground oats, flour,
baking soda, salt, cinnamon, and nutmeg.
In a separate mixing bowl, beat together butter and sugars until well combined.
Add molasses and eggs and beat until fluffy.
Add dry ingredients to the butter mixture and mix together completely.
Spoon 2 tablespoon scoops of dough onto baking sheet, allowing plenty of room for cookies
to spread. You can adjust the size of the dough ball according to how large you want your cookie pies. We made super size oatmeal pies.
Bake cookies for about 10 minutes or just until center of the cookie has spread flat and appears set. Remove from oven and allow to cool for 2-3 minutes or until cookies can be transferred to cooling rack.
Place cooling cookies into freezer for at least 30 minutes while preparing the filling. This will allow them to firm up so that the filling can be pressed between two cookies without squishing the cookie.

Filling Instructions

Cream together butter, vanilla, and marshmallow fluff.
Carefully beat in powdered sugar until combined.

Assembly

Remove two cookies from the freezer.
Use a medium-large cookie dough scoop to scoop a large ball of filling onto the center bottom of one of the cookies.
Press the other cookie onto the filling until the filling squishes out almost to the edge of the cookies.
Continue with remaining cookies.

IS THERE A DIFFERENCE BETWEEN QUICK OATS AND OLD-FASHIONED ROLLED OATS FOR THIS RECIPE?

I use quick oats for this recipe which is important to note because they blend into the cookie much better than the old-fashioned oats which tend to remain chunky.
If you do end up using old-fashioned oats, I suggest that you add them to your blender or food processor so that you are left with smaller pieces that won’t give you an overly chewy cookie. It will also help to prevent your cookie from spreading too much while baking.

IS IT NORMAL FOR THE COOKIES TO BE FLAT AND NOT FLUFFY?

These cookies are intended to be flat and not puffy or thick. With that said, you also don’t want your cookies thin with spots that you can see through the cookie as that is too flat.

If you see your cookies spreading that much while baking, try these tips to rectify it:

Increase your oven temperature to 375 degrees OR
Use the convection bake mode of your oven (if you have that) at 350 degrees OR
Add more flour to your cookie dough (a couple of tablespoons up to 1/4 cup should do it).

HOW SHOULD I STORE THESE OATMEAL PIES?

You can store these cookies at room temperature for a day but I suggest you rather store them in your refrigerator in an airtight container. If you need to stack your cookies, place wax paper between each layer.
Your oatmeal pies will keep for 3-4 days in the refrigerator when stored as directed.
