Add the peanut butter protein powder and yogurt to a large bowl and blend until smooth.
Add vanilla stevia. Blend until smooth.
Taste and decide if it's sweet enough for you. If so, place bowl in the fridge for 1 hour. Line a large baking sheet pan with parchment paper.
Remove from refrigerator and form into 8 balls. I used a large cookie scoop which is about 2 tablespoons. Place the balls onto the baking pan and freeze for 30 min.
After the balls have frozen, melt the low carb chocolate chips in a microwave-safe bowl in the microwave for 30 seconds to a minute. Mix until smooth.
Drop one peanut butter frozen yogurt ball into the melted chocolate, roll it around and use a fork to remove the ball. Tap the edges of the dish to remove excess melted chocolate off the bottom and place ball onto parchment sheet pan.
Once you've coated each ball, place back into the refrigerator to set.
Keep refrigerated in an air-tight container until ready to serve.
