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. Mix until evenly distributed.

Step 2: Mix Wet Ingredients

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

Step 3: Combine Mixtures

Add the dry ingredient mixture to the wet ingredients. 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 at least 30 minutes.

Step 5: Preheat Oven

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

Step 6: Shape Cookies

Divide chilled dough into 32 portions of about 1 tablespoon each. Roll each portion into neat balls. Place them on prepared baking sheets with space between each ball.

Step 7: Bake Cookies

Bake cookies in preheated oven for 13 to 14 minutes. Rotate pans halfway through cooking. The edges should be set while centers still look underbaked. Let cool on pans completely.

Step 8: Make Marshmallow Filling

In a small bowl, combine 1/3 cup of cold water with gelatin; stir and set aside. In a small pot over medium heat, mix sugar and corn syrup with remaining cold water until it resembles wet sand.

Step 9: Cook Sugar Mixture

Cook without stirring until it reaches 180ºF (about 5 minutes). While cooking this mixture, whip egg whites in a stand mixer until soft peaks form.

Step 10: Combine Mixtures

Once sugar mixture reaches 240ºF after approximately another 4 to 5 minutes, remove from heat. Whisk in bloomed gelatin into sugar mixture then slowly stream it into whipped egg whites while mixing on low speed.

Step 11: Whip Marshmallow Filling

Increase mixer speed to high and whip until completely cooled and fluffy—about 11 to 12 minutes. Add vanilla bean paste and mix well to incorporate evenly.

Step 12: Assemble Cookies

Using a greased scoop or piping bag fitted with round tip, generously portion marshmallow onto flat side of half of the cookies. Sandwich another cookie on top of each filled cookie.

Step 13: Set Cookies

Allow assembled oatmeal cream pies to set at room temperature for at least 10 minutes before serving.

Step 14: Storage Information

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

Common Mistakes to Avoid

• Skipping the marshmallow filling preparation steps: Properly blooming and whipping the marshmallow is key to achieving that perfect fluffy texture. Don’t rush this process!

• Not measuring ingredients accurately: Baking is a science. Use a kitchen scale or measuring cups precisely to get the correct ratios for your cookies and filling.

• Ignoring storage instructions: For optimal freshness, store leftover oatmeal cream pies in an airtight container at room temperature.
