2-3 scoops vanilla ice cream
1 or 2 bananas
Chocolate milk

Put 2 or 3 scoops of ice cream in the blender. Slice the bananas and put them in the blender. Add chocolate depending on how rich you want the milkshake. Pour in the milk depending on how thick you want the shake. Turn on the blender. Blend until smooth.

If you want a creamier taste, add 1-2 eggs before blending. (This is true for most other milkshakes, too.)
