How to Make Oatmeal Cream Pies
Step 1: Prepare 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 on high speed for 2 minutes until creamy.
- Add the vanilla extract, 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 cookie dough in the fridge for 15 minutes while preheating the oven to 350°F. Line two baking sheets with parchment paper.
Step 2: Bake the Cookies
- Scoop dough using a cookie scoop to form about 36 cookies (3 dozen).
- Place 12 cookies per baking sheet and return any remaining dough to the fridge between batches.
- Bake for 8–9 minutes or until just set. Let them cool on the baking sheet for 4 minutes before transferring to a wire rack to cool completely.

- In a clean mixing bowl, beat together the butter and marshmallow fluff on high speed for 3 minutes until light and fluffy.
- Add in powdered sugar, vanilla extract, and salt; mix on low speed until combined.

Step 4: Assemble the Cream Pies

How to Perfect Oatmeal Cream Pies

- Chill the Dough: Allowing the dough to chill before baking helps the cookies maintain their shape while baking.

Best Side Dishes for Oatmeal Cream Pies
Oatmeal Cream Pies pair wonderfully with various side dishes that complement their sweet flavor. Consider these options to round out your dessert table.
- Fruit Salad: A refreshing mix of seasonal fruits adds brightness and balance to the rich cream pies.

- Coffee or Espresso: A cup of coffee enhances the flavors of the oatmeal cookies while providing a nice caffeine kick.
- Whipped Cream: A dollop of freshly whipped cream makes for a light addition alongside each pie.
- Chocolate Dipping Sauce: Serve with warm chocolate sauce for dipping, adding another layer of flavor.
- Nutty Granola: A small bowl of crunchy granola can provide texture and additional sweetness if desired.
Common Mistakes to Avoid
To ensure your homemade Oatmeal Cream Pies turn out perfectly, avoid these common pitfalls.
- Using cold ingredients: Make sure your butter and eggs are at room temperature. This helps in achieving a creamy texture for the cookie dough.
- Not measuring flour correctly: Spoon and level the flour or use a kitchen scale for accuracy. Too much flour can lead to dry cookies.
- Skipping the chilling step: Chilling the dough for 15 minutes is essential. It helps the cookies maintain their shape while baking.
- Overbaking the cookies: Keep an eye on the baking time. Oatmeal cookies should be soft and chewy, so take them out when they are just set.
- Ignoring ingredient freshness: Always use fresh spices and ingredients. This impacts the flavor of your Oatmeal Cream Pies significantly.

Frequently Asked Questions
Can I make Oatmeal Cream Pies ahead of time?
Yes! You can prepare the cookies and frosting in advance, then assemble them right before serving.
How do I customize my Oatmeal Cream Pies?
Feel free to add chocolate chips, nuts, or dried fruit to the cookie dough for extra flavor and texture!
Why are my Oatmeal Cream Pies too crumbly?
This can happen if you added too much flour. Always measure accurately and spoon it into your measuring cup instead of scooping directly.
