Mix mascarpone cheese and raspberry preserves in a bowl until smooth and creamy.
Using a 4″ heart-shaped cookie cutter, cut a hole in each piece of bread.
Spread 1 tablespoon of the mascarpone mixture onto each heart.
Flatten raspberries by opening them up with your fingers (check out the picture below).
Place four or five of the flattened raspberries on half of the bread hearts, then top with the remaining bread hearts to make sandwiches.
Serve.
