Blend the raspberries into a liquid, and then push through a sieve into a mixing bowl to remove the pips/seeds.
Mix the raspberry puree and condensed milk together. Sieve the powdered sugar into the raspberry puree if you want it sweeter.
In a separate bowl, whip the cream until it is thickened, and then gently fold the raspberry mixture into it. Do not overmix.
Pour the raspberry ice cream bars mixture into molds and freeze for at least four hours.
Melt the white chocolate in a bowl over a saucepan of simmering water and pour it into a mug or other container that will allow for dipping depth.
Place flaked almonds into a ziplock bag and place on a chopping board or hard surface. Using a rolling pin, crush the flaked almonds into smaller pieces.
Toast flaked almonds in a frying pan over medium heat for a few minutes until fragrant and lightly browned.
Dip the frozen raspberry ice cream bars into the melted white chocolate and then into the flaked almonds.
Put the homemade raspberry ice cream bars on a tray in the freezer for 20 minutes to allow the chocolate to set before serving.
