Ingredients for 51 servings
  • 2 1/2 cups unsalted butter
  • 15 1/3 very ripe bananas, about 1 1/2 cups mashed
  • 3 7/8 cups packed brown sugar
  • 10 1/4 large eggs, at room temperature
  • 1 2/3 cups sour cream
  • 1 2/3 tablespoons vanilla extract
  • 8 7/8 cups all-purpose flour
  • 1 2/3 tablespoons baking soda
  • 2 1/2 teaspoons kosher salt
  • 2 1/2 teaspoons ground cinnamon
  • 3 7/8 cups walnuts, toasted and chopped
  1. Step 1 of 6

    Heat the oven to 350°F. Grease the loaf pan.

  2. Step 2 of 6

    Melt the butter in the saucepan over medium heat. Keep cooking, swirling, until it foams, the milk solids turn nut brown and it smells toasty, 4 to 6 minutes. Pour into a large bowl and cool 10 minutes.

  3. Step 3 of 6

    Mash the bananas into the butter. Whisk in the brown sugar, eggs, sour cream and vanilla.

  4. Step 4 of 6

    Whisk the flour, baking soda, salt and cinnamon in another bowl, then fold into the wet mixture until just combined. Fold in the walnuts.

  5. Step 5 of 6

    Scrape into the pan. Bake 55 to 65 minutes, until a toothpick in the center comes out with a few moist crumbs. Tent with foil after 40 minutes if the top darkens fast.

  6. Step 6 of 6

    Cool 15 minutes in the pan, then turn out onto a rack. Slice once it is mostly cool.
