How to Make Oatmeal Cream Pies

Step 1: Make the Oatmeal Cookies

In a large bowl, whisk together the flour, baking soda, salt, cinnamon, pumpkin pie spice, and oats. Set aside.
In a mixer, beat the butter, brown sugar, and granulated sugar together on high speed for 2 minutes until creamy.
Add the vanilla, molasses, and eggs. Mix on medium speed until fully combined.
Gradually add in the dry ingredients and mix on low speed until just incorporated.
Chill the dough in the fridge for 15 minutes while you preheat the oven to 350°F. Line two baking sheets with parchment paper.
Scoop dough using a cookie scoop to form 36 cookies (about 3 dozen). Place 12 cookies per baking sheet and return remaining dough to the fridge between batches.
Bake for 8–9 minutes or until just set. Let the cookies cool on the baking sheet for 4 minutes before transferring them to a wire rack to cool completely.

Step 2: Make the Marshmallow Cream Frosting

Using a mixer, beat the butter and marshmallow fluff on high speed for 3 minutes until light and fluffy.
Add the powdered sugar, vanilla, and salt. Mix on low until combined; then beat on high for 4 more minutes until airy and spreadable.

Step 3: Assemble the Cream Pies

Pipe or spread marshmallow frosting onto the flat side of one cooled cookie.
Sandwich with another cookie and gently press together.
Chill the cookie sandwiches in the freezer for at least 10 minutes before serving. Store leftovers in the refrigerator if preparing ahead of time.

How to Serve Oatmeal Cream Pies

Oatmeal Cream Pies are delightful on their own, but you can elevate the experience with some creative serving suggestions. Here are a few ideas to enjoy these nostalgic treats even more.

With a Glass of Milk

Pair your Oatmeal Cream Pies with a cold glass of milk. The creamy texture of the milk complements the soft cookies perfectly.

A Scoop of Ice Cream

Serve with a scoop of vanilla or cinnamon ice cream for an indulgent dessert. The cold ice cream contrasts beautifully with the warm spices in the cookies.

Drizzle with Chocolate

Add a drizzle of melted chocolate over each cream pie for an extra touch of sweetness. This adds a rich flavor that enhances the overall experience.

Dust with Powdered Sugar

Lightly dust your Oatmeal Cream Pies with powdered sugar before serving. This simple garnish makes them look elegant and adds a touch of sweetness.

Serve Warm

Warm your Oatmeal Cream Pies slightly in the microwave for about 10 seconds. This makes them even softer and brings out the flavors.

Pair with Coffee or Tea

Enjoy your pies alongside a cup of coffee or tea. The warm beverage complements the spices in the oatmeal cookies beautifully.

How to Perfect Oatmeal Cream Pies

To achieve the best results with your Oatmeal Cream Pies, consider these helpful tips for baking success.

Use room temperature ingredients: Allow butter and eggs to sit out for about 2 hours before baking. This helps create a smoother batter and better texture.
Chill the dough: Refrigerating your cookie dough for at least 15 minutes ensures that cookies hold their shape while baking.
Don’t overmix: Mix until just combined when adding dry ingredients to avoid tough cookies. Gentle mixing keeps them soft and chewy.
Measure flour correctly: Spoon and level flour or use a kitchen scale to prevent dry cookies. Too much flour can ruin their texture.
Bake until just set: Keep an eye on the oven; underbaking slightly keeps cookies soft in the center while they firm up as they cool.
Experiment with spices: Feel free to adjust spices like cinnamon or pumpkin pie spice to suit your taste preferences for an extra flavor boost.

Best Side Dishes for Oatmeal Cream Pies

While Oatmeal Cream Pies are delicious on their own, some side dishes can make for an even more enjoyable meal or snack time. Here are some great pairings:

Fresh Fruit Salad: A mix of seasonal fruits adds freshness and balances the sweetness of the pies.
Yogurt Parfait: Layer yogurt with granola and berries for a creamy, crunchy side that complements the chewy pies.
Chocolate Chip Cookies: For double dessert fun, serve alongside classic chocolate chip cookies for variety.
Nutty Trail Mix: A handful of trail mix provides crunch and healthy fats, making it a perfect complement.
Cheese Platter: Include mild cheeses that contrast nicely with sweet flavors—think brie or goat cheese.
Homemade Hot Chocolate: A warm mug of hot chocolate enhances cozy vibes when enjoying your pies during chilly days.
Caramel Dip: A small bowl of caramel dip is perfect for drizzling or dipping, adding another layer of indulgence.
Cinnamon Applesauce: This warm side dish echoes the spices in oatmeal cookies and adds moisture to every bite.

Common Mistakes to Avoid

Making Oatmeal Cream Pies can be fun and rewarding, but it’s easy to make mistakes. Here are some common pitfalls and how to avoid them.

Incorrect measurements: Using too much flour can lead to dry cookies. Always spoon and level your flour or use a kitchen scale for accuracy.
Skipping the chill time: Not chilling the dough before baking can result in flat cookies. Chill the cookie dough for at least 15 minutes to maintain shape.
Overbaking cookies: Leaving cookies in the oven too long makes them hard. Bake until just set; they will continue to firm up as they cool.
Not using room temperature ingredients: Cold butter and eggs won’t blend well, affecting texture. Let them sit at room temperature for about 2 hours before you start.
Ignoring frosting consistency: If your marshmallow cream frosting is too runny, it won’t hold the sandwich together. Ensure you beat it until light and fluffy.

Storage & Reheating Instructions
