These pretty caramel sandwich cookies are super quick and simple to make. They’re great fun to make with the kids – all you need is some basic cookie ingredients, a jar of dulce de leche and some cookie cutters.
Beat the butter, sugar, egg and vanilla until fully combined.
Fold in the flour and baking powder until you can knead it into a smooth dough.
Wrap the dough in cling film and chill for an hour.
Preheat the oven to 180C (160C fan assisted, 350F).
On a lightly floured surface, roll out the dough to 3mm thick and cut out 12 complete rounds and 12 with a shape punched in the centre. I used this linzer cookie cutter set which works brilliantly and is great for little hands, but you could get a similar effect with one large cookie cutter and one small one.
Line a baking sheet with greaseproof paper – I did mine in two batches.
Bake for 6-8 minutes until just starting to colour.
Remove from the oven and cool on wire rack.
When cool, cover each of the complete rounds in about 1/2-1 tsp of dulce de leche, then top with a punched round to complete, taking care to line up the edges if you used a frilled cutter.
