Step 1

Combine banana, berries and milk in a blender. Blend until smooth. Pour into a bowl.

Step 2

Spoon yogurt into a small plastic bag. Snip off a tiny bit of one corner. Squeezing the yogurt through the hole, pipe 3 or 4 circles on top of the smoothie. Use a toothpick to create the web effect, dragging it from the middle of the bowl to the outside edge.
