Preheat oven to 350 degrees. Prepare a 8x8-inch baking pan by spraying with nonstick cooking spray.
In a small bowl, mix together quinoa, cinnamon, and salt. Pour into the bottom of the baking pan.
Scatter frozen raspberries and sliced banana over the quinoa mixture.
In a blender or food processor blend together the milk, yogurt, egg whites, and collagen peptides until no lumps remain. You can also use a whisk if needed. Pour over the quinoa and fruit. Stir lightly with a fork or spoon.
Bake for 55-60 minutes or until mostly set (only slightly wobbly in the middle). Remove from oven and let cool for at least 30 minutes before slicing.
Store leftovers in an airtight container in the refrigerator for up to 5 days, or the freezer for up to 3 months.
If your quinoa is not pre-rinsed, make sure to rinse under cold running water in a fine mesh strainer (or in a bowl) for 1-2 minutes. This is to rinse off the bitter tasting compound that usually coats these nutritious seeds.
Use any combination of berries you like! Fresh or frozen blueberries, blackberries, or strawberries would all be delicious.
If you double the recipe, bake in a 9x13-inch pan. Baking time will likely be slightly longer, but check after 50-60 minutes.
You can substitute any protein powder for the collagen peptides. Use the quantity of protein powder that adds up to 36 grams of protein (about 1 ½ scoops for most brands).
