I got this recipe from America’s Test Kitchen and have made it several times. Last night multi-tasking did not go well because I was rushing to get all my meal prep and baking done before the Packer game (most dramatic comeback I’ve EVER seen by the way). In my haste I didn’t keep an eye on the bananas while they were in the microwave and had a banana liquid volcano. So word to the wise: keep your eye on the bananas when they’re in the microwave. This has been my go to banana bread recipe ever since I tried it about 5 years ago.
1 3/4 c (8 3/4oz.) all-purpose flour
1 tsp. Baking soda
1/2 tsp salt
2 large eggs
3/4 c (5 1/4oz) packed brown sugar
1 tsp vanilla extract
6 peeled bananas (about 2 1/4lbs.) [see note]
1/2 c chopped walnuts (optional)
8 Tbsp. melted and slightly cool unsalted butter
2 tsp. Granulated sugar
Place 5 bananas in a microwave-safe bowl; cover with plastic wrap and cut several steam vents in plastic with paring knife. Microwave on high power until bananas are soft and have released liquid, about 5 minutes. Transfer bananas to fine-mesh strainer placed over medium bowl and allow to drain, stirring occasionally, 15 minutes (you should have 1/2 to 3/4 cup liquid).
Spray 8 1/2 by 4 1/2-inch loaf pan with nonstick cooking spray. (If you use a 9 by 5-inch loaf pan, start checking for doneness five minutes earlier than advised in the recipe). Whisk flour, baking soda, and salt together in large bowl.
Transfer banana liquid to medium saucepan and cook over medium-high heat until reduced to 1/4 cup, about 5 minutes. Adjust oven rack to middle position and heat oven to 350 degrees. Stir reduced banana liquid into bananas, and mash with potato masher until fairly smooth. Whisk in butter, eggs, brown sugar, and vanilla.
Pour banana mixture into flour mixture and stir until just combined with some streaks of flour remaining. Gently fold in walnuts, if using. Scrape batter into prepared pan. Slice remaining banana diagonally into 1/4-inch-thick slices. Shingle banana slices on top of either side of loaf, leaving 11/2-inch-wide space down center to ensure even rise. Sprinkle granulated sugar evenly over loaf.
Bake until toothpick inserted in center of loaf comes out clean, 55 to 75 minutes. Cool bread in pan on wire rack 15 minutes, then remove loaf from pan and continue to cool on wire rack. Serve warm or at room temperature.
Notes:
Use only very ripe, heavily speckled (or even black) bananas in this recipe. This recipe can be made using 5 thawed frozen bananas; since they release a lot of liquid naturally, they can bypass the microwaving in step 2 and go directly into the fine-mesh strainer. Do not use a thawed frozen banana in step 4; it will be too soft to slice. Instead, simply sprinkle the top of the loaf with sugar. The test kitchen’s preferred loaf pan measures 81/2 by 41/2 inches;
