Using a food processor grind 3 cups of old fashioned rolled oats into fine oat flour. You want 2.75 cups of oat flour so if you end up short, grind more oats into flour. You want to grind for at least two minutes so that your oat flour is very fine. (or you can purchase fine oat flour.)
Add salt, baking soda, and baking powder to the oat flour in the processor. Process or hand mix for 10 seconds.
In a large bowl, whisk together honey, eggs, and unsweetened vanilla almond milk.
Next, add the flour mixture to the wet ingredients and mix until totally combined. The batter will be runny, but should have some resistance. Let the mixture sit for five minutes.
Cut a piece of parchment paper to fit the bottom of the pan, slightly overlapping the edges of the bread pan. Place parchment paper in bread pan and spray parchment paper and sides of bread pan with cooking oil. Add the mixture to your parchment paper-lined bread pan, sprinkle with oats for decoration, and place on the middle rack of the oven horizontally.
Bake for 35-45 minutes until an inserted toothpick comes out clean. Let cool COMPLETELY, ideally overnight. The bread is made just from oat flour, so it is a bit crumbly. If you let it cool completely overnight, it will be far less crumbly!
