Orange Shortbreads Filled With Dulce De Leche - cooking recipe

Ingredients

1 (13.5 oz) can sweetened condensed milk
1 cup butter, at room temperature
2 tsp finely grated orange zest
3/4 cup powdered sugar, plus extra to dust
1 2/3 cups all-purpose flour
2/3 cup cornstarch
2 tsp ground cinnamon

Preparation

Preheat oven to 425\u00b0F.
To make the dulce de leche, pour condensed milk into a ceramic pie dish or shallow baking dish. Cover tightly with foil. Place dish in a medium baking dish and add enough boiling water to come halfway up the side of pie dish. Bake for 1 hour 30 mins, or until caramelized. Remove pie dish from baking dish and let cool. Whisk caramel until smooth then refrigerate until ready to use.
Reduce oven to 325\u00b0F. Line baking trays with parchment paper.
In a stand mixer, beat butter, orange zest and powdered sugar until light and fluffy. Stir in flour, cornstarch and cinnamon, in 2 batches. Dust hands with flour. Roll rounded teaspoonfuls of mixture into balls. Arrange about 1 inch apart on trays. Dip a fork into a little extra flour then flatten cookies gently. Bake for 10 mins. Let cool on trays for 5 mins then transfer to wire racks to cool.
Sandwich shortbreads with dulce de leche. Dust with extra powdered sugar before serving.
