Preheat oven to 275°

Combine flour, oats, iodized salt, brown sugar, 1/2 t cinnamon, and butter in a large bowl. Use your fingers to mix and squeeze the butter together to make thin paper like crumbles.

Whisk together eggs, egg yolks, half and half, 1/2 t cinnamon, and banana extract.

Butter a medium sized casserole dish. Lay toast down to cover the bottom. Cut one or two slices in half to fill the gaps. Lay down the bananas atop the bread.

Pour the half and half mixture over the bread and bananas. Let sit for 10 minutes.

Press oat mixture atop bananas.

Cover and bake 30 minutes. Uncover and bake another 30 minutes.

Garnish by pouring maple syrup and chocolate chips around a slice of the crisp, not atop. Sift powdered sugar atop.
