Pour your cold brew and ice into a glass, leaving about an inch of room at the top. Stir in 1 1/2 tbsp peppermint syrup (the rest will be used in the next step.)
In your milk frother, add 1/2 tbsp peppermint syrup, your peppermint extract, and your nutpods. Push the button for cold foam and let it froth up. *If you don't have a milk frother, just stir these ingredients into the cold brew from step 1.)
Once the cold foam is nice & foamy, pour it on top of the cold brew. Make sure to go nice and slow so that it sits on top of the cold brew. Voila!
