Prepare the cheesecake mixture by combining the softened cream cheese, sugar, and vanilla extract in a bowl.
Add the sour cream to the mixture and blend until fully combined.
Scoop the mixture into small balls, about 1 inch in diameter, and place them on a baking sheet lined with parchment paper.
Freeze the cheesecake bites for at least 2 hours, or until they are firm.
While the bites are freezing, melt the chocolate chips and coconut oil together in a microwave-safe bowl.
Once melted, dip each frozen cheesecake bite into the chocolate and return to the lined baking sheet.
Allow the chocolate to set at room temperature, then refrigerate until ready to serve.
