Ingredients:

Cookies

  • 3/4 cup butter, room temperature
  • 1 cup granulated sugar
  • 1/2 cup light brown sugar
  • 2 tablespoons molasses
  • 2 eggs
  • 1 teaspoons kosher salt
  • 2 teaspoons baking soda
  • 1 teaspoon baking powder
  • 1 teaspoon ground cinnamon
  • 2 cups all purpose flour
  • 2 cups quick oats

Filling

  • 1 tablespoon plus 1 teaspoon unflavored gelatin (about 1 1/2 packets)
  • 1/3 cup plus 1/4 cup water (divided)
  • 3/4 cup granulated sugar
  • 1/4 cup light corn syrup
  • 2 teaspoons vanilla
  • 1 cup powdered sugar
  • 1 cup butter, room temperature

Instructions

Make the Cookies:

Preheat oven to 350°F. Line a baking sheet with parchment paper and set aside.

Make cookie dough: In the bowl of your stand mixer fitted with the paddle attachment mix the butter, granulated sugar, light brown sugar, and molasses together for 2 minutes. Add the eggs, salt baking soda, baking powder, and cinnamon and mix for 1 minute, scraping the sides of the bowl as necessary. Turn the mixer to low and add in the flour and oats, mixing until combined.

Form balls of dough: Using a medium (2- tablespoon) cookie scoop drop the dough on to the prepared baking sheet 3- inches apart. These cookies will spread.

Bake for 10-12 minutes until the edges are golden and centers are just set. Allow the cookies to cool on the baking sheet for at least 5 minutes before transferring to a wire rack, carefully, to cool completely. The centers of the cookies will (and should be) very soft, which is why letting them cool on the baking sheet is an important step.

Make the Filling: 

Mix gelatin and water: In a small bowl, sprinkle the gelatin over 1/3 cup water. Stir it together and let it stand about 5 minutes. Mixture will get thick as it sits.

Heat: In a 2- quart saucepan over medium-high heat, stir together the granulated sugar, corn syrup, and 1/4 cup water until mixture comes to a full boil. Continue boiling for 30 seconds and immediately remove the pan from the heat. Stir in the vanilla and gelatin mixture until it dissolves completely.

Whisk: Transfer the mixture to the clean bowl of your stand mixer fitted with the whisk attachment. With your mixer on medium speed, mix for 20 seconds. Gradually raise the speed to high and mix until the mixture is stiff, white, fluffy, and cooled to barely warm,  5-7 minutes.

Add sugar: Reduce the mixer speed to low and gradually add your powdered sugar, mixing until combined.

Add in the butter. Turn the mixer up to medium speed and mix until completely smooth, about 2 minutes.

Cool briefly: The filling will set up as it sits, so wait until it is thick enough to spread or pipe before filling the cookies, 5-10 minutes. Make sure not to let it sit too long, as it will become too thick and marshmallow-like to spread.

Assemble Cookies

Add filling and top with another cookie: Use a large piping tip or an offset spatula to spread about 2 tablespoons of filling onto the bottoms of half the cookies. Press the remaining cookies onto the filling, creating sandwiches. Allow the cookies to set for 20-30 minutes.


Notes:

Store airtight at room temperature for up to 3 days. Freeze airtight for up to a month.
