Part bananas foster, part French Toast with a frosted corn flakes topping, this recipe has layers of luscious caramelized bananas and rich, buttery croissants bathed in delicious egg custard and topped with crunchy frosted corn flakes!

How To Make Banana French Toast Casserole

  1.  Make The Caramel Mixture. In a microwave safe bowl heat brown sugar, butter and maple syrup in microwave using 45 second intervals, taking ingredients out and stirring after every interval, until butter is melted.
  2. Add Bananas. Add vanilla and cinnamon to caramel mixture, stir well. Add bananas and toss until well coated. Set aside.
  3. Whisk Together The Egg Custard. In a separate bowl, whisk together eggs, half & half, brown sugar and salt. Set aside.
  4. Assemble The Casserole. Cut croissants into halves. Cover the bottom of the casserole dish with ½ of the croissants. Top with ½ of caramelized bananas. Use a spatula to work the bananas over all of the bread. Repeat layers. Pour the egg custard over all of the casserole, making sure to get it into all of the edges, nooks and crannies. Press bread down a little to make sure it is soaking up the custard. Let sit 5-10 minutes or until most of the custard has been absorbed.
  5. Top With Frosted Corn Flakes. Top with 1 C frosted corn flakes cereal. Pour 2 tablespoon melted butter over the corn flakes. Bake in preheated oven for 40-45 minutes or until the center is set. Remove from oven and allow to cool for 5 minutes before slicing and serving with maple syrup.

Making This Ahead Of Time

It can.  However, if you choose to make it the night before, using a sturdier bread like sour dough or an Italian or french loaf would work better (while not changing the taste of the casserole much).  Croissants are delicate and soak up the custard quickly.  They are at their best in this casserole when baked right away.

 Storing Leftovers

 Store leftovers in the refrigerator in an airtight container for up to 3 days. Just keep an eye on the bananas! I don’t recommend freezing.
