3/4 cup cold buttermilk 1/4 cup sugar 2 tsp vanilla extract 1 large egg 1 cup all purpose flour (Bob's Red Mill) 1 cup white whole wheat flour (Bob's Red Mill) 1 tbsp baking powder 1/2 tsp salt 3 tbsp chilled butter (must be cold) cut into small pieces 3/4 cup chocolate chips cooking spray 1 large egg white, lightly beaten 1 1/2 tbsp sugar

Preheat oven to 375°. Combine the first four ingredients in a medium bowl, stirring with a whisk. Spray baking sheet with cooking spray.

Combine flour, baking powder, salt, in a large bowl, stirring with a whisk. Cut in chilled butter with a pastry blender, or you could use 2 knives, until the mixture resembles coarse meal. Gently fold in chocolate chips. Add milk mixture, stirring just until moist.

Place dough onto a floured surface and knead lightly four times with floured hands. Form dough into an 9-inch circle onto baking sheet, about 3/4" thick. Using a knife, cut dough into 12 wedges all the way through.

Brush egg white over dough and sprinkle evenly with sugar. Bake until golden, about 18-20 minutes, depending on your oven. Serve warm.
