Line a baking sheet or square pan with parchment paper if not using popsicle molds.
Whisk the coconut cream, coconut milk concentrate, pistachio butter, and honey or maple syrup until smooth.
Pour the mixture into popsicle molds or the prepared pan. Freeze until firm, at least 3 hours.
If using a pan, cut the frozen mixture into bars.
Melt the chocolate and coconut oil together until smooth.
Dip each frozen bar into the chocolate and sprinkle immediately with crushed pistachios. Freeze briefly until the coating is set.
