Place a patty on a fork and dip into the melted candy melts. Remove, shaking off the excess by tapping the fork on the bowl, and slide onto the prepared baking tray. If desired, immediately sprinkle some patriotic sprinkles on top. Repeat with the remaining patties, melting the additional candy melts when needed, and place the tray in the fridge to set at least 30 minutes. Store in a sealed container in the refrigerator.
