Vanilla Bean Buttercream
- 1 cup salted butter, softened
- 4 cups powdered sugar, sifted
- 2 teaspoons vanilla bean paste
- 2–3 tablespoons heavy cream or whole milk
- Pinch of salt, if needed
Beat the butter for 3–4 minutes until very light and fluffy.
Gradually mix in the powdered sugar.
Add the vanilla bean paste and 2 tablespoons cream. Beat for another 2–3 minutes.
Add additional cream as needed until the frosting is soft and easily spreadable but still holds its shape.
Spread a generous layer over each cooled chai cookie using a small offset spatula.
Finish with a very light dusting of the remaining chai spice.
