This Dulce de Leche Cookies recipe is for buttery shortbread cookies sandwiched together with a delicious and creamy dulce de leche. This recipe is super easy to make and will be an absolute winner for everyone!
Add the butter and sugar to a food processor. Pulse at medium-high speed until light and fluffy.
First, add the whole egg to the creamed mixture with the food processor running, and beat until combined. Then add the egg yolk and vanilla and beat until well combined.
Sift together the flour and salt and add this flour mixture to the egg and butter mixture all at once. Pulse until a dough forms, do not overmix.
Remove the dough from the bowl, cover it in plastic wrap, and refrigerate for 40 minutes to an hour.
Preheat the oven to 160°C (320°F) and line two large baking trays with parchment paper.
Remove the chilled dough from the fridge and roll it out on a floured work surface to a thickness of ½ cm ( ¼ inch) using a rolling pin.
Cut 50 circles out of the dough using a round 7cm (3 inch) diameter cookie cutter. Place the cookies onto an oven tray lined with parchment paper. Bake in a preheated oven for 12 minutes or until the cookies are a light golden brown. Allow the cookies to cool on a cooling rack.
Place the dulce de leche into a mixing bowl and loosen it slightly with a fork. Fill a piping bag fitted with your chosen nozzle with the dulce de leche. Pipe swirls of the caramel onto 25 cookies and then place the plain remaining cookies on top. Dust with icing sugar, serve, and enjoy!
Notes
If you are struggling to roll the dough, it may be because the dough is too warm. Wrap it up in cling film and chill it for another 30 minutes.
