Ingredients

For the Oatmeal Cookies

  • ½ cup unsalted butter . softened
  • ½ cup brown sugar , packed
  • 1 large egg , room temperature
  • ¼ teaspoon fine sea salt
  • 1 teaspoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1 teaspoon pure cocoa powder
  • 2/3 cup all-purpose flour
  • 1 teaspoon baking soda
  • 1 cup quick cooking oats

For the Buttercream Filling

  • ½ cup unsalted butter softened
  • ½ cup powdered sugar
  • 1 teaspoon vanilla extract
  • 2 tablespoons heavy cream

Instructions

For the Oatmeal Cookies

  • Preheat the oven to 350°F and line two cookie sheets with parchment paper. Set aside.
  • In a medium bowl, sift the flour and baking soda or whisk well to combine.
  • In a separate bowl, using a hand mixer cream the softened butter and brown sugar until fluffy. Add the egg, salt, vanilla, cinnamon, and cocoa powder. Mix well to combine until fully incorporated.
  • Combine the flour mixture into the butter, then mix until just combined. Add in the rolled oats and mix until homogenous, without overbeating.
  • Use a cookie or ice cream scoop to form 20 individual cookies. Place them onto the lined cookie sheets, at least 2-3 inches apart.
  • Bake for 8 minutes or until golden brown. For extra flat cookies, press them down with a spatula as soon as they come out of the oven. This also helps make the top appear cracked. Afterwards, carefully transfer them to a cooling rack.

For the Buttercream Filling

  • Using a hand mixer, cream the softened butter and sugar until fluffy, for about 2-3 minutes.
  • Add in the vanilla extract and heavy cream, then mix again for 2 minutes. Sprinkle in a pinch of salt if it tastes too sweet.

Assembling the Oatmeal Cream Pies

  • Place the buttercream into a piping bag fitted with a ½ inch nozzle.
  • Pipe buttercream onto the bottom of a cookie, without overfilling. Sandwich with another cookie, then repeat the process for all remaining cookies.
