Pre-heat oven to 350 degrees.
Meanwhile place the stick of butter in a 9x13 in pan and place in oven to melt butter.
In a large bowl combine apples, 2 teaspoons cinnamon, and mix to coat.
Once butter is melted pour 1/4 cup from the pan and set aside. This should leave you with about 1/4 cup left in the pan.
Pour the apple mixture into the pan and spread evenly. Â Drizzle 1/4 cup of honey over the apples.
Combine the oats, 1 teaspoon cinnamon, baking powder, ginger, nutmeg, and salt. Mix to combine.
Add the eggs, milk, kefir, remaining 1/4 cup honey, and butter to the oat mixture. Mix to combine and pour over the apple mixture. Spread evenly.
