Grease the bottom of a glass or heavy bottomed baking dish with cooking spray or butter. Pour the dulce de leche into the bottom of the baking dish and use a spatula to spread the dulce de leche into an even thin layer.
Slice 2-3 bananas into one inch thick slices. Arrange the slices in the bottom of the baking dish. Add pecanes between the slices of banana along with about half of the cubes of cream cheese.
Cut the French bread loaf into 1-2 inch thick slices and then cut each slice in half lenthwise. This will help the bread to absorb the most liquid. Pack the slices into the baking dish as close as they can be in a single layer. Use smaller slices to fill gaps.
Pour the milk and eggs mixture over the bread as evenly as possible so that all of the bread is in contact with the liquid. Use the bottom of the whisk to press any higher pieces down into the liquid.
Cover the dish with foil to chill and let the bread soak for at least 4 hours - or overnight. The longer it soaks, the better.
Preheat the oven to 350 F | 175 C. Remove the baking dish from the fridge and return to room temperature.
While the oven preheats, mix together the ingredients for the brown sugar bourbon bits - the mixture should be crumbly. Only stir until the flour is absorbed into the liquid and the bits are bite sized.
Add fresh banana and the rest of the cream cheese to the top of the casserole. Sprinkle the brown sugar bits over the top of the casserole in an even layer.
Bake the casserole for 20-30 minutes while covered with foil, then remove the foil and continue to bake for another 10-15 minutes, until the tops of the casserole is golden brown and toasted.
Let the casserole rest for about 10 minutes prior to slicing for best results. Top the bananas foster French toast with a scoop of vanilla ice cream and an extra drizzle of dulce de leche. Enjoy!
