Pour the Milk, 1 cup of rum, cinnamon, nutmeg, espresso beans and eggs into a bowl and whisk until combined. In a deep pan, pour the mixture over the slices of bread, and allow to sit until soaked. Set aside.
In a pan, add a half a stick of butter over med-high heat. Slice the bananas, add to the pan, let them simmer until they start to brown. Add a pinch of salt, mixed nuts, and brown sugar, once caramelized add a half cup of rum, and light on fire.
In a separate pan, add the other half of butter over med-high heat, add the slices of bread until browned.
Add the french toast, 2 tablespoons of the bananas foster mixture, top with whip cream and powdered sugar. Adding salted caramel to it also is delicious....enjoy!
