Stir in oats, raspberries and maple syrup. Simmer for 3-5 minutes until oats thicken and cook through. Remove from heat.
Sprinkling in a little at a time, quickly stir in collagen peptides. (Collagen peptides are prone to clumping, but if you stir it as you add it, I find it prevents it!)
Serve into a bowl and top with peanut butter, hemp seeds, and extra frozen raspberries!
