Start by making your peanut butter granola base. In a large bowl mix together oats, peanut butter, maple syrup, vanilla, coconut oil, and a little salt.
In a parchment lined 8x8 pan, press and even layer of the granola mixture over the bottom with a spoon.
In your high speed blender mix together your strawberries and yogurt until well combined.
Pour strawberry mixture over granola evenly.
Optional: Melt a few frozen strawberries and use the strawberry juice to create swirls in the yogurt bars. Using a spoon pour a small dime-sized amount of strawberry juice scattered across the bars. With a fork or toothpick, drag the dot until a swirl forms.
Top with thin slices of strawberries. (Optional: Cut your strawberries in a heart shaped for a beautiful dessert that's also festive for Valentine's Day!)
Freeze bars for 2 hours.
Cut into squares and store in a container in the freezer with parchment between bars.
When ready to eat, remove from freezer and let thaw for 4-5 minutes before eating.
