Preheat oven to 400 degrees and line 2 baking sheets with parchment paper.

Unfold puff pastry and cut into squares. Arrange 4 squares on each tray.

Using a sharp knife, score the edges of each puff pastry square about 1/2” from the edge (basically you’re making a square inside so that the edges will puff properly as it bakes. Make sure not to cut all the way through the pastry).

Spread a little butter on each square.

Mix cinnamon and sugar together. Sprinkle about 1 TBSP over each square.

Arrange apple slices on top of the sugar.

If desired, sprinkle each with a bit of raw sugar.

Bake for 18-20 minutes, or until golden brown.

Optional apricot glaze: warm the jam and water in the microwave until the jam is warm and loose (about 10-15 seconds). Brush the apples and pastry with the jam to give it a nice shine.

If desired, top with ice cream and caramel sauce. Or, top with powdered sugar.
