Line a small, rimmed baking sheet with parchment paper.
In a medium bowl stir the yogurt, maple syrup, and vanilla. Blend until all incorporated.
Spread the yogurt mixture evenly on the prepared baking sheet and place the blueberries and strawberries around the sheet. Sprinkle with chocolate chips.
Place in the freezer for at least 3 hours. Cut or break into pieces and enjoy!
To cut -let the bark defrost a little bit – makes it easier.
Store bark in an airtight container in the freezer for up to 3 months.
