Line a plate with parchment paper. Combine the blueberries, yogurt, and a dash of vanilla extract in a large bowl.
Scoop 5-6 clusters onto the parchment paper and place in the freezer for 30 minutes to an hour.
Combine the coconut oil and chocolate chips in a microwave safe bowl. Melt together until fully combined.
Dip each cluster in the chocolate mixture and place back in the freezer for 20 minutes. Once the chocolate is hardened around the yogurt, enjoy, or store the leftovers in the freezer.
