Preheat oven to 400°F.
Slice each croissant in half. Spread the inside of the bottom half of the croissant with 1 ounce cream cheese. Top with one slice of swiss cheese, then 1/4 of the ham and top with another slice of swiss cheese. Repeat for all 4 sandwiches.
Wrap each sandwich in Reynolds Wrap® Aluminum Foil and place on a baking sheet.
Bake for 10 minutes until the cheese is melted and the ham is heated through.
Serve dusted with powdered sugar and dipped in raspberry jam.
