1 large egg, 1 1/4 cup buttermilk, 1 tablespoon vanilla extract
Pour wet mixture into flour, mix using wooden spoon or dough whisk. Add remaining buttermilk as needed to just moisten flour to form a shaggy dough. A shaggy dough should be thick and slightly sticky, but not wet and soggy.
Tip dough onto heavily floured surface. Pat or roll out into a rectangle roughly 10" x 8". Sprinkle top of the dough with the chai streusel mixture. Fold the dough like a tri-fold letter. Tuck in edges to enclose streusel completely.
Divide into 2- 1" tall disks and slice into 6 wedges each.
Place on parchment lined baking sheet and allow to chill in freezer for 20 minutes.
While dough chills, preheat oven to 425°F.
Once dough is chilled, brush the top with egg wash. Make sugar topping by combining course sugar, cinnamon and cardamom and sprinkle over the top of each wedge.
