Place steel cut oats in a large bowl and cover with the two cups of boiling water. Let sit uncovered at room temperature for 2 hours. Stir once half way through.

Preheat oven to 350 degrees.

In a medium bowl, sift flour, baking powder, cinnamon, and salt.

In a small microwave safe bowl, melt butter and honey then stir into bowl with oats.

Beat egg into milk and alternately add milk mixture and flour mixture to large bowl with oats stirring with a wooden spoon as you add each. Do not over mix, just mix to combine wet into dry. Fold in diced apple pieces.

Generously spray two standard size loaf pans (8X5) with non-stick cooking spray and scrape the dough into the pan, using half the batter for each. Using a spatula, smooth out the top then place in oven for 70 minutes (one hour and ten minutes), or until a tooth pick inserted in center comes out clean. The dough is dense so we recommend leaving in for the full 70 minutes.

As soon as the bread comes out of the oven, remove from pan and cool on a wire rack to cool completely. Slice and serve with additional drizzled honey.
