Place a sheet of parchment paper on a baking sheet with sides and set aside. No need to grease it with butter or spray it with oil to stick the paper to it. The yogurt will weigh it down later.
In a small mixing bowl, add yogurt and stir through chocolate chips.
Dollop yogurt mixture onto the baking sheet with the parchment paper. Spread it out in an even layer right to the edges with a rubber spatula or the back of a spoon.
Slice strawberries, or dice them if you prefer them smaller which is great for kids.
Top yogurt with sliced strawberries and then the bluebberries.
Sprinkle over granola.
Place baking sheet into your freezer and freeze for 4+ hours or overnight until solid and completely frozen.
Remove from freezer, quickly lift it out of the baking sheet using the sides of the parchment paper and place it onto a chopping board.
Using a large sharp knife, slice it into bars or random chards, like a chocolate bark.
Enjoy a few pieces or immediately place into a freezer-friendly airtight container, with a sheet of parchment paper between any layers to avoid sticking, and place it back into the freezer. The yogurt will begin to melt quite quickly being at room temperature.
Enjoy!
