In a large mixing bowl, whisk the rolled oats, all purpose flour, whole wheat flour, active dry yeast, and salt.
Add the warm water and honey, and mix with a large spoon until it forms a sticky dough.
On a lightly floured surface, knead the dough by hand for 5 minutes, until it’s smooth and elastic. Shape the dough into a ball and place it back in the same mixing bowl.
Cover the mixing bowl with a clean kitchen towel and let rise in a warm place until it about doubles in size, after about 1.5 to 2 hours.
Grease or line a 9x5 loaf pan with parchment paper. Set aside.
On a clean work surface, shape the dough into an oval. Gently spread the top edges of the dough down the sides and underneath, to create tension on the top. All the seams or edges of the dough should be tucked underneath.
Place the dough seam-side-down in the prepared loaf pan. Cover the dough again with a towel and allow it to proof for about 30 minutes. The dough is done proofing once an indent made by your finger into the dough springs back after 2-3 seconds.
Preheat the oven to 375°F.
Drizzle a little honey on the top of the loaf and use your fingers or a pastry brush to spread it out. Sprinkle a small handful of rolled oats on top.
Bake the loaf for 30 to 40 minutes, until it’s golden on top and sounds hollow when tapped. Allow the loaf to cool for 10 minutes, then remove it from the loaf pan. Allow it to finish cooling on a cooling rack for at least 1 hour before slicing. Enjoy!!
