For paleo and/or dairy-free, simply use compliant chocolate chips and replace the heavy whipping cream with full-fat canned coconut milk. For the coconut milk, I recommend using Thai Kitchen, Sprouts, or Native Forest brands. Other brands may lend an aftertaste so these are the only brands I recommend. When canned coconut cream gets cold, it separates. If your can has separated, simply heat it in a saucepan over medium-low heat until combined.
