Line a small baking sheet with wax paper.  Slice banana and arrange in single layer on baking sheet, then add blueberries in a single layer.  Freeze for 2-3 hours.

Mix yogurt and casein protein powder, then place in freezer for 30 minutes.

In a food processor, combine yogurt mixture and cream cheese.  Then add blueberries and banana and pulse until smooth.  Add a couple tablespoons of almond milk if you need to help it blend.

Serve immediately.  Top with crumbled graham cracker or granola if desired.
