  Prep Time 35 minutes

  Cook Time 15 minutes

  Cooling Time 14 minutes

  Total Time 1 hour 4 minutes

  Ingredients

  For the Oatmeal Cookies

  • 2 sticks 226 g unsalted butter, softened
  • 1 cup packed dark brown sugar
  • 1/4 cup granulated sugar
  • 1 large egg room temperature
  • 1 tablespoon unsulphured molasses
  • 2 teaspoons vanilla extract
  • 2 1/2 cups quick oats
  • 1 1/2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon kosher salt

  For the Vanilla Cream Filling

  • 1 stick 113 g unsalted butter, softened
  • 2 cups powdered sugar
  • 1 tablespoon heavy cream
  • 1 1/2 teaspoons vanilla extract
  • 1/4 teaspoon kosher salt

  Instructions

  1. Preheat your oven to 375°F (190°C). Line two large baking trays with parchment paper to prevent sticking and ensure even baking.
  2. For the best results, allow the butter, egg, and heavy cream to come to room temperature before you begin.
  3. In a large mixing bowl, beat the softened butter, dark brown sugar, and granulated sugar together until the mixture becomes light, fluffy, and creamy. This usually takes about 3 minutes.
  4. Scrape down the sides of the bowl halfway through to make sure everything blends evenly.
  5. Mix in the egg, molasses, and vanilla extract until smooth and fully incorporated. The molasses adds the signature warmth and rich flavor that makes these cookies taste just like the classic version.
  6. Add the quick oats, flour, baking soda, cinnamon, and salt to the bowl. Mix only until no dry flour remains. The dough will be thick and slightly sticky, which is exactly what you want for soft cookies.
  7. Using a 2-tablespoon cookie scoop, portion the dough onto the prepared baking sheets, leaving about 3 inches of space between each cookie. If you don't own a cookie scoop, simply roll equal portions by hand to keep the cookies uniform for sandwiching later.
  8. Bake one tray at a time for 8 to 10 minutes.
  9. The cookies are ready when the edges are lightly golden while the centers still look slightly under baked. This helps them stay soft after cooling. Allow the cookies to cool on the baking sheet for about 10 minutes before transferring them to a wire rack. Let them cool completely before adding the filling.
  10. While the cookies cool, beat the softened butter until creamy. Gradually add the powdered sugar, then mix in the heavy cream, vanilla extract, and salt. Continue beating until the filling becomes smooth, fluffy, and light.
  11. Turn half of the cooled cookies upside down.
  12. Spread or pipe approximately 1½ tablespoons of vanilla filling onto each cookie. Place another cookie on top and gently press until the filling spreads close to the edges. Serve immediately or store for later.
  
  

  Helpful Baking Tips

  Choose Quick Oats

  Quick oats create the soft, tender texture these cookies are famous for. If you only have old-fashioned oats, pulse them a few times in a food processor to make them finer.

  Don’t Skip the Molasses

  Molasses gives these cookies their classic deep flavor and subtle caramel notes. Even a small amount makes a noticeable difference.

  Avoid Overbaking

  The cookies should still look slightly soft in the center when you remove them from the oven. They’ll continue cooking on the baking sheet and stay wonderfully chewy.

  Make Every Cookie the Same Size

  Using a cookie scoop helps create evenly sized cookies, making it easier to build neat sandwich cookies.

  Create Perfectly Round Cookies

  Immediately after baking, place a slightly larger drinking glass over each cookie and gently swirl it in a circle to create perfectly round edges.

  Easy Recipe Variations

  • Replace the vanilla buttercream with cream cheese frosting for a tangy twist.
  • Add a pinch of nutmeg for extra warmth.
  • Stir mini chocolate chips into the dough for a fun variation.
  • Use store-bought vanilla frosting if you’re short on time.

  Storage Tips

  Store assembled oatmeal cream pies in an airtight container at room temperature for up to 4 days.

  For longer freshness, refrigerate them for up to 5 days. The cookies actually become even softer after resting overnight, making them even more delicious.
