Add 1–2 tablespoons mocha sauce to a glass. Brew 2 shots of espresso directly over the sauce and stir well until fully dissolved.
Add ice to the glass, then pour in 6–8 ounces of 2% milk. Stir gently and set aside.
In a separate cup, combine the pistachio sauce, 2% milk, and heavy cream. Use a handheld milk frother to froth until the mixture becomes thick and creamy (about 15-20 seconds).
Pour the pistachio cream cold foam over the iced mocha.
Finish with a light sprinkle of McCormick Brown Butter Seasoning on top.
Serve immediately and enjoy your homemade Starbucks Iced Dubai Chocolate Mocha.
