In a large bowl, combine the <a href="http://www.craftfoxes.com/dashboard/how_tos/frienship-bread-starter-recipe/preview">bread starter,</a> 3 tablespoons oil, egg, and 1⁄3 cup sugar. Stir to combine. Add salt, baking soda, cinnamon, and enough flour to create a firm dough.
Turn out onto a floured surface and knead 8–10 minutes. Add flour only to reduce stickiness. Return to bowl, oil the top, and cover with a damp cloth or plastic wrap. Rise at room temperature until doubled in volume, about 1 hour.
Coat two 9" × 5" loaf pans with pan spray, and line the bottom and short sides of each pan with a strip of parchment. Turn risen dough onto a floured surface, divide into 2 equal portions, and shape each into an oblong loaf. Place into the prepared pans seam-side down. Dust with flour, cover loosely with plastic wrap, and set aside to proof for 30 minutes. Preheat oven to 350°F.
Dust the risen loaves with sugar and bake until golden brown and hollow sounding, about 35–50 minutes. Cool 10 minutes, remove from pans, and cool completely on a rack.
