In a large mixing bowl, combine flour, oat flour (if using),  baking soda, baking powder, salt, spices and brown sugar. Whisk to combine.

Add the cubed butter and toss with the dry ingredients. Then use a pastry blender to work the butter into small pea sized shapes. It is OK to have some larger and some smaller.

Add in the pecans and toffee bits.

In a large measuring cup, whisk together egg, buttermilk, pumpkin puree, and vanilla.

Pour the wet ingredients into the dry ingredients and use a spatula or wooden spoon to gently blend the mixture into a ragged dough.

With floured hands, form the dough into a ball and drop onto a floured surface. Gently combine the dough without overworking it, into two 6-8″ circles or squares. Do not pat to thin. Dough should be thick, because whoever heard of a skinny scone? Try not to add too much flour, but you do want enough to get this to come softly together. Cut your dough into sixteen scones and place on a parchment lined cookie sheet.

Preheat your oven to 400 degrees.

Chill in a cold refrigerator for about 20 minutes. Place in oven and bake for 18-20 minutes. Let cool and then glaze.

While scones are baking, make the glaze. In a large measuring cup or a small bowl, combine powdered sugar, bourbon and vanilla extract. Whisk together and stir in a few tablespoons of milk or cream until glaze becomes icing consistency.
