How to Make Oatmeal Cream Pies Step-by-Step Instructions

1. Prepare Your Workspace

Preheat your oven to 350 degrees. Line two baking sheets with parchment paper. This keeps cookies from sticking.

2. Mix the Wet Ingredients

In a large bowl, beat the butter, brown sugar, and white sugar together until light and fluffy. This takes about 2 minutes. Add vanilla extract, molasses, and eggs. Mix until everything is combined and smooth.

3. Combine the Dry Ingredients

In a separate bowl, whisk together flour, baking soda, salt, cinnamon, pumpkin pie spice, and nutmeg. This spreads the spices evenly through the dough.

4. Make the Cookie Dough

Slowly add the dry ingredients to the wet mixture. Mix on low speed until just combined. Fold in the oats with a spoon or spatula. Don’t overmix or cookies will be tough.

5. Shape and Bake the Cookies

Scoop dough into tablespoon-sized portions. Roll into balls and place on prepared baking sheets about 2 inches apart. Flatten each ball slightly with your hand. Bake for 10 to 12 minutes until edges are set but centers still look soft. Let cookies cool on the baking sheet for 5 minutes, then move to a wire rack to cool completely.

6. Make the Marshmallow Cream Frosting

While cookies cool, beat butter until creamy. Add marshmallow fluff and mix well. Gradually add powdered sugar, vanilla extract, and salt. Beat on medium speed until frosting is light and fluffy, about 2 minutes.

7. Assemble the Cream Pies

Turn half of the cooled cookies upside down. Spread or pipe about 2 tablespoons of frosting onto the flat side of each cookie. Top with another cookie to make a sandwich. Press gently so frosting spreads to the edges.

Serving and Decoration

How to Serve Oatmeal Cream Pies:

These cookies are perfect for many occasions:

• Lunchbox Treats: Wrap individually in plastic wrap for easy packing.
• Dessert Plates: Serve with a glass of cold milk.
• Party Platters: Arrange on a serving tray for gatherings.
• Gift Boxes: Stack in a pretty box tied with ribbon for homemade gifts.

Storing Oatmeal Cream Pies

• Room Temperature: Store in an airtight container for up to 3 days. The cookies stay soft and fresh.
• Refrigerator: Keep cream pies in the fridge for up to 5 days if your kitchen is warm. Bring to room temperature before serving.
• Freezer: Freeze assembled cream pies in a freezer-safe container for up to 2 months. Thaw in the refrigerator overnight.
• Cookie Dough: Freeze unbaked cookie dough balls for up to 3 months. Bake from frozen, adding 1 to 2 extra minutes.

Tips and Tricks for Success

• Don’t Overbake: Remove cookies when centers still look slightly soft. They will firm up as they cool.
• Room Temperature Ingredients: Bring butter and eggs to room temperature for smoother mixing.
• Chill the Dough: If dough seems too soft, refrigerate for 15 minutes before scooping.
• Uniform Size: Use a cookie scoop to make all cookies the same size so they bake evenly.
• Cool Completely: Make sure cookies are totally cool before adding frosting or it will melt.
• Soft Brown Sugar: If your brown sugar is hard, microwave it with a damp paper towel for 20 seconds.

Oatmeal Cream Pies FAQs

Can I use quick oats instead of old-fashioned oats? Old-fashioned oats work best because they create better texture. Quick oats can make cookies mushy.

Why are my cookies hard? Overbaking makes cookies hard. Remove them when centers still look soft. They firm up as they cool.

Can I make these without molasses? Molasses adds flavor and softness, but you can replace it with honey or maple syrup if needed.

How do I keep the frosting from melting? Make sure cookies are completely cool before frosting. Store finished cream pies in a cool place or the refrigerator.

Can I use store-bought frosting? Yes, but homemade marshmallow frosting tastes much better and stays fluffy.
