Step 1

First, prepare the croissants. Cut them in half, spread some Nutella inside, and place some banana slices on top. Repeat with all.

Step 2

Spray a 9x13 dish with baking spray, and arrange the stuffed croissants inside.

Step 3

In a small bowl, whisk together the milk, eggs, vanilla, sugar, and cinnamon.

Step 4

Pour mixture over the croissants, making sure that they are mostly submerged. Cover with plastic wrap, and place in fridge overnight.

Step 5

When ready to bake, preheat oven to 350F. Bake for 50-55 minutes, until cooked through and no longer jiggly. Serve warm!
