First, prep the cold brew by adding the ice, cold brew, and one teaspoon of vanilla syrup to a cup and giving it a good stir.
Then, make the Golden Foam: using a blender or milk frother, combine the heavy cream, milk, and the other teaspoon of vanilla syrup, then blend until thick and foamy.
Add the olive oil to the sweet cream and reblend until foamy.
Top the cold brew with the golden foam, and enjoy.
