Whip the cream and milk

• Pour the cold heavy cream and whole milk into the bowl of a stand mixer.
• Mix on medium speed until foamy.

Add the sweetener and vanilla

• Add the powdered sugar, vanilla extract and vanilla bean paste.
• Mix on medium-high speed until the mixture starts to thicken.

Finish whipping

• Scrape down the bowl so everything is nicely incorporated.
• Mix on high speed until the foam reaches a thick, pipeable consistency, being careful not to overmix.

Store and serve

• Transfer the cold foam to a piping bag and keep it in the fridge.
• Snip off the end of the bag and pipe the foam over your favorite iced latte. Use within about 3 days.
