Pulse about 2 cups of GF oats in a blender or food processor until smooth. Sift and discard any large pieces. Then, measure oat flour. You need to have about 2 cups of oat flour. Sometimes, depending on the size of the oats, it makes a little less. In this case, simply blend more oats, sift, and re-measure. Save any leftover oat flour in a sealed container and use it another time.
For the Honey Oat Bread:
Preheat oven to 350 F.
Grease a non-stick loaf pan with some butter or cooking spray. Tip: You can also use parchment paper so you can easily pick the bread up out of the pan once done. Note: The paper may make some lines/indents on the sides of the bread.
Add oat flour to a medium-sized bowl along with GF all-purpose flour, baking powder, baking soda, and salt. Stir until evenly distributed.
In a large mixing bowl, whisk eggs, honey, and almond milk.
Add dry ingredients to the wet ingredients and mix until well combined. The batter should be relatively thick, like a cake. Allow to rest for 5 minutes.
Using a silicone spatula, spoon batter into your prepared loaf pan. For an artisanal touch; sprinkle some whole oats (not the oat flour) on top of the bread.
Bake for 30-40 minutes, or until a toothpick inserted into the center comes out clean. Cool for 10-15 minutes in the pan.
Serve warm with a pat of butter and a drizzle of honey.
