Whisk together milk, eggs, vanilla extract, sugar, cinnamon powder, and salt in a bowl.

Place a pan on medium heat and melt butter.

Dip each bread slice in the egg mixture, soaking both sides.

Transfer the soaked bread to the warm pan.

Cook each side for 3 minutes on medium heat, until golden and crispy.

In another pan, melt butter and add sugar.

Keep the heat on low to gradually caramelize the sugar.

Once the sugar melts and turns light golden brown, add the sliced bananas and vanilla extract.

Cook the bananas until the sugar is syrupy and the bananas have caramelized.

Place the French toasts on a plate.

Top with caramelized bananas and syrup.

Serve immediately.
