In a small cup, combine the instant coffee, vanilla pudding mix and boiling water. Stir until smooth - it should be gelled and not too clumpy. (Don’t worry if there are a couple of lumps though - you’ll be blending it!)
Combine the coffee mixture, vanilla extract, ice cubes and milk in a blender. Blend until smooth and creamy. Enjoy immediately.
Top with whipped cream, if using.
