Make the Purple Layer (Bottom):
Blend frozen blueberries, milk, banana, honey, and ice until smooth.
Pour into the bottom of a tall clear cup.
Make the Green Layer (Middle):
In a small bowl, mix vanilla yogurt with matcha powder or green coloring.
Carefully spoon it over the purple layer to create separation.
Make the Blue Layer (Top):
Blend vanilla milk, blue coloring, and whipped topping or cream cheese with a few ice cubes.
Gently pour over the green layer for a third distinct color.
Toppings & Finish:
Top with whipped cream, then sprinkle with edible glitter or star-shaped sprinkles.
Add a swirl of pastel-colored syrup or frosting if desired.
Serve with a straw and a little blacklight glow for fun photos if using tonic water.
