Jus Alpukat (Indonesian Avocado Coffee Shake)

1 cup whole milk, plus additional as needed

1/2 cup condensed milk

2 medium avocados

1/4 cup coffee

Pinch of salt

Chocolate syrup for drizzling

Place whole milk, condensed milk, avocado, ice cubes, coffee, and salt in a blender. Blend on high speed until smooth, for 30 seconds to 1 minute; if the shake is too thick, blend in additional milk to thin it slightly.

If desired, drizzle chocolate syrup inside the serving glasses, then pour the shake evenly into the glasses, and serve.
