Get all your ingredients ready before you start. You'll need a mixing bowl, electric mixer, tall glass, and a spoon.
Take your mixing bowl and add 1 tablespoon instant coffee, 30 ml non-dairy cream, 1 tablespoon coconut sugar, and 1 tablespoon oat milk. These all go in together.
Turn your electric mixer to medium-high speed. Start whipping the mixture. Keep going for about 3-5 minutes. You'll know it's ready when the mixture gets light and fluffy, like whipped cream. If you lift your beater, the mixture should hold its shape and form a little peak.
While you wait for your coffee mixture to whip, grab your tall glass. Fill it with ice cubes, but leave about 2 inches of space at the top. Pour in your cold milk or coconut water over the ice.
Now comes the fun part. Take your whipped coffee mixture and gently spoon it on top of your cold milk. Don't stir it in - just let it sit on top. You can use the back of your spoon to make some pretty swirls if you want.
For the finishing touch, sprinkle some cocoa powder on top using your mesh sieve. This makes it look extra nice and adds a bit of chocolate flavor.
Your drink is ready to serve right away. Give it a stir before you drink it to mix all the layers together.
Remember: This drink tastes best when you drink it right away. The whipped coffee will slowly start to mix with the milk if you leave it sitting too long.
