  • 2 medium bananas, diced The riper the bananas, the sweeter the flavor.
  • 8 large eggs, room temperature, beaten
  • 2 cups whole milk, room temperature For richness.
  • 1/2 cup heavy whipping cream Adds extra creaminess.
  • 1/2 cup creamy peanut butter, melted Use a quality brand like Jif or Skippy for maximum flavor.
  • 1/4 cup light brown sugar, packed For that caramelized sweetness.

Method
 

Preparation
  1. Spray a 9×13 inch baking dish with nonstick cooking spray.
  2. Add half of the bread cubes in an even layer along the bottom of the dish, followed by half of the diced bananas. Repeat with the remaining bread and bananas.
  3. In a large bowl, whisk together the eggs, milk, heavy cream, peanut butter, brown sugar, vanilla, cinnamon, and salt until smooth and fully combined.
  4. Pour the custard mixture evenly over the layered bread and bananas, pressing down gently to ensure the bread absorbs the liquid. Cover the dish with plastic wrap and refrigerate overnight.
Baking
  1. When ready to bake, remove the plastic wrap and let the dish sit at room temperature for 20-30 minutes while preheating the oven to 350°F (175°C).
  2. Cover the dish with aluminum foil and bake for 30 minutes. Then, remove the foil and bake for an additional 15-20 minutes until the center is set and does not jiggle.
  3. Once done, let it cool slightly before serving.
Serving
  1. Top with melted peanut butter, sliced bananas, and crushed peanuts. Serve warm with maple syrup if desired.

Notes

Store leftovers in an airtight container in the refrigerator for up to 3 days. You can reheat slices in the microwave. Make it a day in advance for best flavor.
