Ingredients for 49 servings

• 580 ml unsalted butter
• 14 2/3 very ripe bananas, about 1 1/2 cups mashed
• 870 ml packed brown sugar
• 9 3/4 large eggs, at room temperature
• 385 ml sour cream
• 24 ml vanilla extract
• 2.03 liters all-purpose flour
• 24 ml baking soda
• 12 ml kosher salt
• 12 ml ground cinnamon
• 870 ml walnuts, toasted and chopped

1. Step 1 of 6

   Heat the oven to 175°C. 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.
