Preheat oven to 375°F.

Roll out the pie dough and using a biscuit cutter or similar, cut out 3-inch circles of dough on a silpat mat.

Chop candy bars up and place 1 tablespoon on each circle of dough (2 minis does three dough circles), fold over the dough and crimp edges to seal.

Place dough on a foil or silpat lined baking sheet and cut a couple of small slits into each calzone.

Bake for 20 minutes or until golden brown.

Allow to cool then drizzle with prepared cookie icing and sprinkles.

Allow icing to set up for 45 minutes to harden.
