In a food processor, throw 3 of the apples (the rest is diced and mixed in at the end), honey, and cinnamon and puree (scrape down sides as necessary).
Continue w/ the rest of the wet ingredients and pulse a few times to thoroughly mix.
In a large bowl, whisk together the dry ingredients.
Mix in the wet.
Dice the remaining apple and mix in.
Pour into the pan.
Bake 30-40 minutes (done when a knife inserted in the middle comes out clean!)
