While yeast is proofing, combine olive oil and xanthan gum in a small bowl and mix until combined. set aside.
Place Baking blend, oat fiber and salt into your mixing bowl, Do not use a dough hook, either use the regular mixing paddle or the whisk attachment to combine the flours. Pour in the yeast mixture, oil and xanthan mixture, and eggs. Add the vinegar while mixer is on low speed. Increase to high and beat for 3 minutes.
Scoop ½ the dough into 1 side of your pan and get your hands REALLY wet with water to form the loaf. Repeat for other ½ of the dough
You may need to re-wet your hands to form and smooth the top of your loaves
Quickly score/slash the top of the loaves. Cover pan with a damp kitchen towel and allow to rise for 1 hour in a warm draft free space.
Place into preheated oven for 10 minutes, reduce heat to 350 and continue baking for an additional 50 minutes. You may need to tent the loaves with foil so that they do not over brown
