In a medium bowl, stir together the powdered peanut butter, applesauce, and vanilla yogurt until completely combined and a thick, smooth mixture forms.
Divide the mixture evenly among 8 balls or silicone muffin cups or molds.
Place the dark chocolate chips and coconut oil in a small microwave-safe bowl. Microwave in 15-second intervals, stirring between each, until completely melted and smooth, about 75 seconds total.
Drizzle the melted chocolate evenly over all 8 servings.
Refrigerate until firm and set. For a firmer, frozen-treat texture, place in the freezer and allow to soften for a few minutes before eating.
Store covered in the refrigerator or freezer.
