Ingredients

Scale

Shortbread Cookies

  • 225 g / 8 oz (2 sticks) unsalted butter, softened
  • 1/2 cup icing sugar (powdered sugar), plus extra for dusting work surface
  • 2 cups plain flour

Filling

  • Dulce De Leche (see Slow Cooker Dulce De Leche – 1 ingredient recipe)

Instructions

  1. Preheat the Oven: Set your oven to 180C/350F to prepare for baking the cookies.
  2. Prepare Baking Trays: Line one or two baking trays with parchment paper, depending on their size, to ensure cookies don’t stick.
  3. Mix Butter and Icing Sugar: In a bowl, combine the softened butter and icing sugar and mix until you achieve a smooth, well-combined mixture.
  4. Add Flour and Form Dough: Gradually add plain flour to the butter-sugar mixture; initially, it will look crumbly but keep mixing until it starts to form a dough. Use your hands to roughly shape it into a ball.
  5. Roll Out Dough: Dust your work surface with icing sugar and turn the dough out onto it. Flatten the dough to about 1cm (1/2 inch) thick using your hand, then cover with a sheet of baking paper and roll gently with a rolling pin to an even 0.5cm (1/4 inch) thickness.
  6. Cut Cookie Rounds: Using a 6.5cm (2.5 inch) round cookie cutter, cut out cookie shapes from the rolled dough. Transfer them carefully to the prepared baking tray using a knife or egg flip.
  7. Re-roll Excess Dough: Gather the leftover dough scraps into a ball, roll out again, and continue cutting cookies until you have about 16 rounds total.
  8. Bake the Cookies: Place the trays in the preheated oven and bake the cookies for 15 to 18 minutes until they turn pale golden brown with slightly browned edges. Though they may seem undercooked, they will firm up as they cool.
  9. Cool the Cookies: Remove the cookies from the oven and allow them to cool completely on the baking trays.
  10. Assemble Cookie Sandwiches: Once cool, spread a generous dollop of Dulce De Leche onto half of the cookies. Sandwich each filled cookie with a plain cookie to create delicious shortbread cookie sandwiches.

Notes

  • Make sure the butter is softened to room temperature for easy mixing and a smooth dough consistency.
  • Dust the work surface generously with icing sugar to prevent the dough from sticking since it’s quite soft.
  • If you don’t have Dulce De Leche on hand, you can substitute with caramel sauce or use sweetened condensed milk cooked until thickened.
  • Store the assembled cookie sandwiches in an airtight container to keep them fresh for up to 3-4 days.
  • The cookies will seem soft right out of the oven but will crisp up as they cool, so avoid overbaking.
