Homemade Oatmeal Cream Pies: A Nostalgic Treat

There’s a certain magic to the scent of cinnamon and oats baking in the oven. It instantly transports me back to my grandmother’s kitchen, where she’d be humming a tune while pulling out a tray of golden-brown cookies. While she was famous for her chocolate chip cookies, I always had a soft spot for her oatmeal cookies. They were soft, chewy, and perfectly spiced. These oatmeal cream pies are a nostalgic nod to those beloved cookies, taken to the next level with a creamy, dreamy filling.

Recipe Overview

Total Time: 29 minutes

Ingredients

For the Oatmeal Cookies:

1 cup brown sugar
½ cup melted butter
1 egg
1 teaspoon vanilla
1 cup flour
½ teaspoon cinnamon
1 ½ teaspoons cocoa powder
½ teaspoon baking soda
½ teaspoon baking powder
¼ teaspoon salt
1 cup rolled oats

For the Cream Filling:

1 cup vegetable shortening
1 cup powdered sugar
2 teaspoons vanilla
1 (7 ½ ounce) jar marshmallow fluff

Equipment Needed

Baking sheets
Parchment paper
Medium mixing bowl
Electric mixer
Measuring cups and spoons
Tablespoon-sized scoop (optional)
Piping bag or zip-top bag

Instructions

Preheat your oven to 350 degrees F (175 degrees C). Line your baking sheets with parchment paper. This prevents sticking and makes cleanup a breeze.
In a medium bowl, sift together the flour, cinnamon, cocoa powder, baking soda, baking powder, and salt. Sifting ensures that these dry ingredients are evenly distributed and prevents lumps in your cookie dough. Set aside this dry mixture.
In a larger bowl, using an electric mixer, cream together the brown sugar, melted butter, egg, and vanilla. Beat until the mixture is smooth and well combined. The creaming process is crucial for achieving a tender cookie.
Gradually add the dry mixture to the wet ingredients, mixing on low speed until just combined. Be careful not to overmix, as this can develop the gluten in the flour and result in tough cookies.
Stir in the rolled oats. Ensure they’re evenly distributed throughout the dough.
Use a tablespoon-sized scoop (or two spoons) to form equal-sized dough balls. Place the dough balls onto the prepared baking sheets, leaving plenty of space between them (about 2 inches) to allow for spreading during baking.
Bake for 7-9 minutes. Keep a close eye on the cookies, as baking times can vary depending on your oven. They should be golden brown around the edges and slightly soft in the center.
Allow the cookies to cool completely on the baking sheets before carefully transferring them to a wire rack. It’s important to let them cool fully before moving them, as they will be delicate while still warm.
While the cookies are cooling, prepare the cream filling. In a clean bowl, cream together the vegetable shortening, powdered sugar, and vanilla until the mixture is smooth and fluffy.
Mix in the marshmallow fluff until it is fully incorporated and the filling is light and airy.
To assemble the oatmeal cream pies, match up two cookies that are approximately the same size and shape.
Turn one cookie over (bottom side up).
Use a piping bag (or a zip-top bag with a corner snipped off) to pipe the cream filling onto the bottom cookie. Piping the filling is much neater and easier than trying to spread it with a knife. Alternatively, you can use a spoon, but be careful not to tear the cookie.
Top with the other cookie and gently press down to evenly distribute the filling.

Expert Tips & Tricks

For extra-soft cookies, add a tablespoon of molasses to the dough along with the wet ingredients.
If you find your cookies are spreading too much, chill the dough in the refrigerator for 30 minutes before scooping and baking.
Don’t overbake! Slightly underbaked cookies are preferable to overbaked ones in this recipe.
For a richer, more intense cocoa flavor, use dark cocoa powder.
If you don’t have marshmallow fluff, you can make your own or substitute with a thick buttercream frosting.

Serving & Storage Suggestions

Serve these homemade oatmeal cream pies immediately or chill them in the refrigerator for later. They are best enjoyed cold, as the filling firms up and the cookies become even chewier.

Store leftover cream pies in an airtight container in the refrigerator for up to 3 days. The cookies may soften slightly over time, but they will still be delicious.

I do not recommend freezing these cream pies, as the filling may become icy and the cookies may lose their texture upon thawing.

Variations & Substitutions

Gluten-Free: Substitute the all-purpose flour with a gluten-free all-purpose blend. Be sure to choose a blend that contains xanthan gum for proper binding.
Dairy-Free: Use a dairy-free butter substitute for the melted butter in the cookie dough. For the filling, you can try using a vegan marshmallow fluff alternative and a dairy-free shortening.
Spice it up: Add a pinch of ground cloves or nutmeg to the cookie dough for a warmer, spicier flavor profile.
Nutty Delight: Add chopped pecans or walnuts to the cookie dough for extra texture and flavor.
Peanut Butter Filling: Replace half of the marshmallow fluff with peanut butter for a delicious peanut butter cream pie.

FAQs (Frequently Asked Questions)

Q: Can I make the oatmeal cookies ahead of time?
A: Yes, you can bake the oatmeal cookies a day or two in advance and store them in an airtight container at room temperature. Just be sure to let them cool completely before storing.

Q: Can I use a different type of sugar?
A: While brown sugar is recommended for its flavor and moisture, you can substitute with granulated sugar or coconut sugar if needed. The texture and flavor of the cookies may vary slightly.

Q: Why is my filling too soft?
A: Make sure your vegetable shortening is cold, but not solid. If it is too warm, the filling won’t set up properly. You can also try chilling the filling in the refrigerator for 30 minutes before assembling the pies.

Q: Can I add chocolate chips to the oatmeal cookies?
A: Absolutely! Chocolate chips would be a delicious addition to these oatmeal cookies. Fold them into the dough along with the rolled oats.

Q: My cookies are sticking to the parchment paper. What can I do?
A: Make sure you are using good quality parchment paper. If they are still sticking, you can lightly grease the parchment paper with cooking spray before placing the dough balls on top.
