Combine hemp hearts, cocoa powder, chocolate chips, heavy cream, chia seeds, liquid stevia, and a pinch of salt in a bowl.
Stir everything together until well combined. Ensure there are no dry pockets of cocoa powder.
Cover the bowl tightly and refrigerate for at least 4 hours, or preferably overnight, to allow the flavors to meld and the mixture to thicken.
Before serving, give the oatmeal a good stir. If it's too thick, you can add a splash more cream or a tablespoon of water.
Serve chilled. For an extra decadent treat, top with a few more low-carb chocolate chips or a dollop of whipped cream.
Enjoy your guilt-free, rich, and satisfying keto chocolate oatmeal!
