Start by adding your white chocolate sauce, espresso and syrup if you choose to your glass. Mix with a frother until well combined. You can also use cold brew rather than espresso if preferred.
Add in your ice and milk.
To a separate glass add your heavy cream, coffee creamer, and syrup, if desired. Mix with a frother until thick. I like mine pretty thick.
Top with cookie icing and sanding sugar. Just like a Little Debbie Christmas Tree Cake!
