This frosty treat looks like it came right from a 50s diner, and is ever-so-simple to make.

White layer:
1 frozen banana
1/2 cup sweetened vanilla yogurt
1/4 cup milk

Blend and spoon into 2 glasses. Place glasses in freezer.

Pink layer:
1/2 cup sweetened vanilla yogurt
1 cup frozen raspberries

Blend and spoon second layer in glasses. Place back in freezer.

Blue layer:
1/2 cup sweetened vanilla yogurt
1 cup frozen blueberries

Blend and spoon third layer in glasses.

Note: I used a Ninja blender for this recipe. If using a regular blender, you may need to add milk to the pink and blue layers.
