Preheat the oven to 350°F. Grease the baking dish with 2 tablespoons coconut oil
In a large bowl, mash the 3 medium bananas with a fork.
Add the 3 large eggs with the 2 cups milk of choice, 1/2 cup honey, and 2 teaspoons vanilla extract, and whisk until combined.
Add in the 1 bread loaf cubes and half of the 3.5 ounces dark chocolate. Stir to combine, then transfer to your prepared dish. Top with sliced 1 medium banana and sprinkle with the remaining chopped chocolate.
Bake for 30-35 minutes, or until lightly golden. (see notes)
Notes
You may want to cover the bread pudding with foil for the first 15 minutes and then uncover it for the last 15-20 minutes to prevent the bread from browning too much.
Consider adding some chopped walnuts or sliced almonds.
