Ingredients

  • For the Oatmeal Cookies
  • 1 cup (240 g) unsalted butter, softened
  • 1 cup (200 g) brown sugar, packed
  • ½ cup (100 g) granulated sugar
  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1¾ cups (220 g) all-purpose flour
  • 1 teaspoon baking soda
  • ½ teaspoon salt
  • 1 teaspoon ground cinnamon
  • 3 cups (240 g) old-fashioned rolled oats
  • For the Cream Filling
  • ½ cup (115 g) unsalted butter, softened
  • ½ cup (60 g) vegetable shortening
  • to 2 cups (180–240 g) powdered sugar, sifted
  • 1½ teaspoons vanilla extract
  • 12 tablespoons milk or cream

Instructions

  • Preheat & Prep: Preheat oven to 350 °F (175 °C). Line baking sheets with parchment paper.
  • Cookies – Cream Butter & Sugars: In a large bowl, cream together butter and both sugars until light and fluffy.
  • Add Eggs & Vanilla: Beat in eggs one at a time, then stir in vanilla.
  • Combine Dry Ingredients: In a separate bowl, whisk flour, baking soda, salt, and cinnamon. Gradually add into butter mixture.
  • Stir in Oats: Fold in the oats until evenly distributed.
  • Shape Cookies: Drop rounded tablespoons of dough (or use a small ice cream scoop) onto baking sheets, spacing about 2 inches apart. Flatten slightly.
  • Bake: Bake 10–12 minutes, until edges are light golden.
  • Cool: Allow cookies to cool on the pan for 5 minutes, then transfer to a wire rack to cool completely.
  • Make Filling: In a mixing bowl, beat butter and shortening until smooth. Gradually add powdered sugar, then mix in vanilla. Add milk until the filling reaches a piping consistency.
  • Assemble Pies: Pair cookies of similar size. Pipe or spoon filling onto one cookie and top with the other, pressing gently.
  • Chill (optional): Chill in the fridge for 30 minutes to set, if desired.

Notes

  • For extra flavor, toast the oats in a skillet for a few minutes before adding.
  • Customize the filling with a pinch of cinnamon or a drop of maple extract.
  • Sandwiches keep well stored in an airtight container—refrigerate for up to 5 days or freeze for up to 2 months.
