Make the banana-egg mixture. Place the ripe bananas, eggs, whole milk, granulated sugar, vanilla extract, cinnamon, nutmeg, and a pinch of sea salt into the bowl of a food processor or a high-powered blender. Blend until the mixture is smooth and free of lumps.
Prep the bread. Slice the bread into 1-inch thick slices.
Heat the oil. Heat a large skillet or griddle over medium heat and add 1 tablespoon of coconut oil or unsalted butter.
Dip the bread. Dip each slice of bread into the banana-egg mixture, ensuring both sides are well coated (soak for about 30 seconds until the bottom half is thoroughly saturated, then use a fork to gently flip the bread and allow it to soak for another side 30 seconds). Let any excess batter drip off.
Cook. Place the coated bread slices onto the hot skillet or griddle. Cook for 3-4 minutes on each side or until golden brown and slightly crispy. Continue this process, adding more coconut oil or butter to the skillet as needed until all the bread slices are cooked.
Transfer to a plate. Arrange the Banana French Toast slices on a serving platter.
Add syrup and toppings. Drizzle the french toast with pure maple syrup and top with slices of banana and chopped pecans.
Serve. Add a dollop of chocolate hazelnut spread on the side, and enjoy.
