Instructions

1. Step 1: Preheat oven to 350°F. In a large skillet over medium heat, melt 4 tbsp unsalted butter. Add 1/2 cup packed brown sugar and stir until dissolved and bubbling.
2. Step 2: Carefully stir in 2 tbsp light rum and cook for 1-2 minutes until the sauce thickens slightly. Add 3 medium sliced ripe bananas and cook for 3 minutes, turning gently to caramelize the bananas. Remove from heat.
3. Step 3: In a large bowl, whisk 8 large eggs, 2 cups whole milk, 1/2 cup heavy cream, 2 tsp vanilla extract, 1 tsp ground cinnamon, and 1/4 tsp salt until fully blended.
4. Step 4: In a greased 9x13 inch baking dish, layer half of the 1-inch cubed French bread, then spread the caramelized bananas and sauce evenly over it, followed by the remaining bread cubes.
5. Step 5: Pour the egg mixture evenly over the bread and bananas, pressing gently to submerge the bread. Let sit for 10 minutes to soak.
6. Step 6: Bake uncovered for 45-50 minutes until the top is golden and a knife inserted in the center comes out clean.
7. Step 7: Allow to cool for 10 minutes, dust with powdered sugar, and serve warm.
