Crush the Oreos in a blender or food processor. Add the cream cheese and knead into a kind of dough. Knead the dough into a sort of disc, as if you were rolling it out. Put it on a plate on a sheet of baking paper and cut out a heart with the cutter. Place all the Oreo hearts on a plate in the fridge for at least an hour.
When the hearts have cooled sufficiently to set, melt the chocolate (in a double boiler or microwave). Dip the Oreo hearts in the chocolate and place them on a sheet of baking paper. Sprinkle the Valentine sprinkles on top immediately, while the chocolate is still soft.
How to store
Store the Valentine Oreo Truffles in a sealed container in the fridge for about 4-5 days.
