Gather the ingredients.
Brew the strong coffee and let it chill. Use a refrigerator or freezer to speed up the process, or just let it chill in the fridge overnight.
Add the strong chilled coffee, milk, and sweetened condensed milk to a blender.
Split the vanilla bean. Use half of the split bean and scrape the seeds out. Place the seeds in the blender. Add in the vanilla extract. Fill the blender the rest of the way with ice (leaving a little room at the top for blending)
Blend until smooth. Serve with whipped cream.
Frappuccinos can also be frozen in mason jars and kept in the freezer for up to 3 months!
