Begin the bananas Foster by melting ¼ cup butter in a pan over medium heat.
Stir in the brown sugar, ½ teaspoon of cinnamon, and maple syrup.
Once it's bubbling, add the rum and mix. Let it simmer for 2 minutes.
Add the sliced bananas and cook for 5 minutes, spooning the sauce over the bananas.
Cover the pan and continue to simmer over low heat until you're ready to top the French toast with it.
To start the French toast, in a shallow bowl, whisk together the eggs, heavy cream, granulated sugar, and vanilla extract.
Dip the bread slices into the mixture, soaking each side for about 20 seconds.
In a medium skillet, melt 1 tablespoon of butter over medium heat.
Cook the bread in the pan, about 2 to 3 minutes per side, in batches. Add some more of the remaining butter to the pan with each batch.
Once done cooking the French toast, remove the bananas Foster from the heat and pour over the French toast. Garnish with the remaining cinnamon and, if desired, diced pecans.
