Set a 2½ to 3-inch heart-shaped cookie cutter or coeur à la cr éme mold on a plate. In a bowl, beat the cheese with a fork until smooth. Pack the cheese into the cookie cutter and smooth the top. Cover and refrigerate until cold, at least 1 hour and up to 3 days. Gently unmold the cheese onto the center of a plate. Serve with the baguette toasts.
