Place the Cinnamon Toast Crunch into a sandwich bag and seal well.
Then, using your hands or a rolling pin, crush the cereal until it resembles granola sized pieces.
Grab a mason jar and apply a small layer of vanilla greek yogurt on the bottom.
Then add in a layer of the crushed Cinnamon Toast Crunch.
On top of the cereal, add in some fresh berries of your choice (raspberries, blueberries, or blackberries).
Repeat this process until your mason jar is completely full. Making sure to alternate the berry layers to make it a red, white, and blue pattern.
Add more crushed Cinnamon Toast Crunch to the very top to garnish the parfait and enjoy!
