Step 1

In a small microwave-safe bowl, heat the coconut oil in 15-second bursts, just until it melts. Set aside to cool to room temperature.

Step 2

Place a rack in the center of your oven and preheat the oven to 350 degrees F. Coat a 9x5-inch baking pan with nonstick spray. Line the pan with parchment paper so that the paper overhangs both sides, then lightly coat with spray again.

Step 3

In a large mixing bowl, whisk together the almond flour, flaxseed meal, baking soda, cinnamon (if using), and salt. In a separate bowl, whisk together the eggs, egg white, honey, apple cider vinegar, and cooled coconut oil until smooth. And the wet ingredients to the dry ingredients and, with a whisk or rubber spatula, stir until well combined. The batter will be thick and wet, like a muffin batter. Transfer to the prepared loaf pan and smooth the top.

Step 4

Bake until the top is toasty golden brown and a toothpick inserted in the center of the loaf comes out clean, about 35 to 40 minutes. Place the pan on a cooling rack and let cool in the pan for 10 minutes. Transfer from the pan to the rack (use the parchment overhang) and let cool completely. Slice and serve.
