Step 1

Prep: Preheat the oven to 350F and line a 8×3″ baking pan with parchment paper. Mix the ground flax and water together in a small bowl and let sit for at least 5 minutes, to thicken.

Step 2

Dry Ingredients: in a large bowl, whisk the oat flour, ginger, cinnamon, cloves, nutmeg, baking powder, baking soda, and salt together until evenly distributed.

Step 3

Wet Ingredients: in a separate bowl, mix the thickened flax, sugar, applesauce, molasses, oil, and vinegar together. Add the wet ingredients to the dry ingredients and mix well, until no dry clumps of oat flour remain.

Step 4

Bake: pour the batter into the loaf pan, then top with turbinado sugar, if desired. Bake in the middle rack of the oven for 35 to 37 minutes, or until the top is risen and a toothpick inserted in the center of the bread comes out only with crumbs. Remove from the oven and let sit in the pan for 5 minutes before transferring to a cooling rack to let cool completely.

Step 5

Glaze (optional): Combine the powdered sugar and milk together in a small bowl; mix until a smooth and thick glaze forms.

Step 6

Serve: Drizzle with icing sugar, then slice and serve. Store leftovers at room temperature, in a container with a loose-fitting lid, for up to 5 days. Pre-sliced pieces of the loaf can also be frozen for up to 2 months and reheated as necessary.
