Irish Soda Bread

2 cups whole wheat bread flour
1 1/2 cups all-purpose flour, extra for dusting
1/2 cup old-fashioned rolled oats
2 tablespoons brown sugar
2 teaspoons salt
1 teaspoon baking soda
1 teaspoon baking powder
3 tablespoons unsalted butter, cold
1 1/2 cups buttermilk
1 egg
Preheat oven to 350 degrees F.
In a large bowl, combine the flours, oats, brown sugar, salt, baking soda, and baking powder. Cut the cold butter into small pieces and add to the dry ingredients, blend by hand until the mixture looks like cornmeal.
In a small bowl, whisk together the buttermilk and egg. Using a strong utensil or your hands, mix the wet and dry ingredients together until the dough can be formed into a ball.
Place the dough on a lightly floured surface and knead for 5 minutes until soft and elastic. Shape the dough into a round loaf, about 6 inches in diameter. Place on a greased baking sheet. Dust the top of the loaf with flour. Use a sharp knife to cut an X into the dough, about half the depth of the loaf and to 1-inch of the edge. Bake for 45 to 50 minutes. Makes one loaf of bread
