• Preheat the oven to 400 degrees F.
• Into a large bowl, sift together the flour, baking powder, sugar, cream of tartar, and salt.
  4 Cups Flour, 2 Tablespoons Baking Powder, 1 Tablespoon Sugar, 1 Tablespoon Cream of Tartar, 1 teaspoon Salt
• Add the butter pieces into the flour mixture and toss until all of the pieces are coated well in flour. Now, press the butter to flatten, then toss again to evenly distribute in the flour.
  1 Cup Butter
• Stir in the chocolate chips and orange zest until just combined.
  1 1/2 Cups Semisweet Chocolate Chips, 1 Orange
• In a medium bowl, whisk together the cream, 2 eggs, (set aside the yolk and 1 tablespoon of cream for the egg wash) and 1/2 cup milk until well blended. Pour into the flour mixture and mix just until combined.
  1/2 Cup Heavy Cream, 2 Eggs, 1/2 Cup Milk
• Lightly coat 1 large loaf pan or two regular bread pans with nonstick cooking spray. Lightly flour the counter.
• Squeeze the dough together in the palms of your hands to get it to stick into a mass. Transfer the dough to your prepared surface and gently shape into a rectangular loaf and place in the bread pan.
• If making two loaves, cut the dough into two equal portions, carefully lift and insert them into the greased pans.
• In a small bowl, beat the egg yolk with the remaining tablespoon of cream. Brush the tops of the loaf with the milk mixture.
  1 Egg Yolk, 1/2 Cup Heavy Cream
• Bake until golden brown, about 25-30 minutes for two pans, or 45-60 minutes for a large loaf.
• Let cool for 5 to 10 minutes on a wire rack and then pour the glaze over. Don't worry about using all of it. Serve warm.
