Gather all of your ingredients.
In a mixing bowl, crack your eggs and whisk together the heavy whipping cream and salt. Once well blended, whisk in the cinnamon until there are no clumps in the mixture.
Heat a non-stick pan over medium high heat. Dip a slice of bread into the egg mixture, flipping to ensure both sides have been fully coated.
Using a pair of tongs, place the dipped bread directly into the preheated pan. Cook for about 2 minutes, then flip and cook for an additional 2 minutes. Each side should be golden brown. Move the slice to a plate and repeat with the rest of the bread.
Trim the ends of a banana, remove the peel, and slice evenly into thin coins.
On one side of the bread, place slices of banana over the whole surface. Top with another slice of bread.
Generously dust the tops with powdered sugar, then drizzle with warm caramel sauce just before serving.
