• 12 tablespoons (170g) unsalted butter, melted
• 1 cup (213g) dark brown sugar, packed
• 1 tablespoon (20g) molasses
• 1 large egg
• 1 large egg yolk

For the Marshmallow Filling

• 2/3 cup (152g) water, cold; divided
• 1 package (7g) unflavored gelatin, powdered

How to Make Oatmeal Cream Pies with Marshmallow Filling

Step 1: Prepare Dry Ingredients

In a medium bowl, combine the flour, oats, spices, baking powder, baking soda, and salt.

Step 2: Mix Wet Ingredients

In a large bowl, whisk together the melted butter, brown sugar, and molasses until well combined. Then whisk in the egg and egg yolk until fully incorporated.

Step 3: Combine Mixtures

Add the dry ingredient mixture to the wet mixture. Stir with a spatula until a soft dough forms.

Step 4: Chill Dough

Cover the bowl with plastic wrap and chill in the refrigerator for 30 minutes to firm up.

Step 5: Preheat Oven

Preheat your oven to 350ºF with racks positioned in the upper and lower thirds. Line two baking sheets with parchment paper.

Step 6: Form Cookies

Divide the chilled dough into 32 portions of about 1 tablespoon (24g) each. Roll them into neat balls and place them on prepared baking sheets, spaced evenly apart (16 per sheet).

Step 7: Bake Cookies

Bake the cookies for 13 to 14 minutes, rotating pans halfway through. They should be set around the edges but look slightly underbaked in the center. Allow cookies to cool completely on pans.

Step 8: Make Marshmallow Filling

To prepare marshmallow filling, combine 1/3 cup of cold water with gelatin in a small bowl and set aside. In another pot, mix granulated sugar and corn syrup with remaining water until it resembles wet sand.

Step 9: Heat Sugar Mixture

Cook over medium heat without stirring until it reaches 180ºF (about 5 minutes). While this cooks, whip egg whites to soft peaks using a stand mixer fitted with a whisk attachment.

Step 10: Combine Ingredients

Once sugar mixture reaches 240ºF on a candy thermometer, remove from heat. Whisk in bloomed gelatin while slowly pouring it into whipped egg whites at medium-low speed.

Step 11: Whip Filling

Increase speed to high and whip until cooled completely and fluffy—around 11 to 12 minutes. Add vanilla bean paste or vanilla extract just before finishing mixing.

Step 12: Fill Cookies

Using either a greased scoop or piping bag fitted with round tip, fill half of cooled cookies generously with marshmallow filling before topping each with another cookie.

Step 13: Set Cookies

Let assembled oatmeal cream pies rest for at least ten minutes before enjoying them!

Step 14: Store Leftovers

Store any leftover oatmeal cream pies in an airtight container at room temperature for up to three days.

Common Mistakes to Avoid

• Not chilling the dough: Chilling the dough for 30 minutes is essential for better texture and flavor. Skipping this step can result in flat cookies.

• Improper measuring of ingredients: Use a kitchen scale or proper measuring cups. Incorrect measurements can alter the texture and taste of your cookies.

• Skipping the marshmallow filling preparation steps: Follow the instructions carefully when making the marshmallow filling. Each step plays a vital role in achieving the right consistency.
