3 1/2 C. whole-wheat flour
2/3 C. sugar
4 tsps. baking powder
1 tsp. baking soda
1 tsp. tsp. salt
1 tsp. ground cinnamon
2 large eggs
1 C. buttermilk plus up to 2 tablespoons, if needed
1 tsp. vanilla extract
14 T. (2 sticks minus 2 T.) cold unsalted butter, cut into 1/3-inch cubes
1 1/2 C, cup quick-cooking oats (not instant)
6 oz. chocolate chips
2/3 C walnut pieces, toasted then chopped
Preheat oven to 375 degrees. Line a baking sheet with parchment paper.
In a large bowl, whisk together the flour, sugar, baking powder, baking soda, salt and cinnamon. In a separate bowl, whisk together the eggs, buttermilk and vanilla.
Add the cold butter cubes to the flour mixture and use your hands to work them into the flour, breaking up and flattening some of the chunks as you go, for 1 to 2 minutes, or until you have some shaggy pieces and some small chunks of butter remaining. You will still have plenty of loose flour, not a cohesive dough.
Add the egg mixture to the flour mixture and stir for a few seconds to barely moisten the flour. Add the oats, chocolate and walnuts, and stir gently just until ingredients are combined. The dough will be thick and will not come together into a ball. If you still have some dry oats or bits of flour at the bottom of the bowl, add up to 2 tablespoons of buttermilk, a few drops at a time, so that all of the ingredients are just moistened. You don't need a wet dough in order to pat it together in the next step.
Turn the dough onto a lightly floured surface and pat it together into 2 balls with floured hands, kneading once or twice. Flatten each ball into a thick disk and roll it into a circle, about 8 inches in diameter and 3/4-inch thick. Lightly dust the dough and work surface with flour as needed to prevent sticking. Cut the each dough disk into 8 wedges with a large, floured knife and transfer the cut scones to the prepared baking sheet, leaving about 1 inch of space between the scones.
Bake for 13 to 15 minutes, or until bottoms are golden brown and a toothpick inserted in the center comes out clean. Cool on baking sheet for 5 minutes, then transfer to a wire rack. Serve warm or at room temperature.
We freeze our scones, taking them out one at a time to defrost on the subway ride and munch on them at our desks.
