Grease 2 bread pans with butter and set aside.
In the bowl of an electric mixer, combine warm water (just barely warm to your wrist) with the yeast, and honey, stir until dissolved.
Once the yeast has proofed, add 2 cups of Einkorn flour, avocado oil, and salt. Using the dough hook attachment, mix until combined and then for 2-3 minutes, or until the dough is smooth.
Continue to add Einkorn flour ¼ cup at a time until the dough is pulling away from the sides of the mixing bowl. Cover the dough with plastic wrap or a kitchen towel and let it rise for 30 minutes, or until doubled in size.
Press the dough down and then allow it to rise again until doubled.
Once it has risen twice, transfer the dough to a lightly floured surface and divide into 2. Shape each ball of dough into a roughly 6" x 6" square. Roll the dough up and tuck the edges under, then place into the greased bread pans.
In a small bowl, whisk together the egg and water. Brush the egg wash over the tops of each loaf, then allow to rise for another 30 minutes.
Preheat the oven to 350 degrees.
Bake in the preheated oven for 30-40 minutes, or until golden brown on top.
Remove from the oven and allow the bread to cool completely before slicing. Enjoy!
