Make the Berry Layer:
In a blender, combine strawberries, raspberries, blueberries, milk, yogurt (or ice cream), sweetener (if using), and ice.
Blend until smooth.
Pour into glasses, filling halfway. Place in the freezer while you prepare the next layer to keep them separate.
Make the Sunrise Layer:
Rinse the blender or use a clean one.
Add chunks, milk, yogurt or ice cream, vanilla, and ice. Blend until smooth.
Gently pour this over the berry layer to create a beautiful two-tone effect.
Add Toppings:
Finish with whipped cream and a few fresh berries or a drizzle of syrup if desired.
