This recipe is inspired by the banana bread I made during my childhood from "The Blender Cookbook." I can't find it anywhere online. I think it's from the manual that came with our blender.
This month, I've been snacking on bananas with yogurt and chopped peanuts. This recipe takes these ingredients to another level. If you add chocolate sauce and vanilla bean ice cream, it's a lovely riff on a banana split. Feel free to use any kind of nut for the streusel topping. The streusel is an integral part of the banana bread, so don't skip it. You mix it down and it becomes one with the batter.
Make sure to undercook this banana bread. You must take it out when it's still gooey in the center. Otherwise the bread will be dry and you will be sad. —Phyllis Grant
one 9- by 5-inch loaf
unsalted butter (for the streusel)
brown sugar (for the streusel)
all-purpose flour (for the streusel)
kosher salt (for the streusel)
roasted and salted peanuts, finely chopped
Heat oven to 350° F. Grease your loaf pan (you'll want one that's at least 3 inches deep) with butter and coat with a thin dusting of flour.
For the streusel: Melt 1/4 cup of butter. Stir in the 1/2 cup sugar, 1/3 cup flour, and 1/4 teaspoon salt. Mix in the nuts. Set aside.
For the cake: Place the 1/2 cup of butter in a medium pan over medium heat. Once it's melted, don't walk away. Take it off the heat once the sizzling stops (4 to 5 minutes) and brown bits drop down to the bottom of the pan. Set aside to cool.
Whisk together the flour, baking soda, baking powder, and salt. Set aside.
In the bowl of your food processor, combine the brown butter, bananas, eggs, brown sugar, white sugar, yogurt, orange juice, and vanilla extract. Blend until almost smooth (about 15 seconds). If you see any chunks of banana, pulse for a few more seconds.
Pour the wet ingredients over the combined dry ingredients. Carefully fold together. Make sure to incorporate all of the flour pockets but be careful not to overmix. Spoon into your greased loaf pan. Pour the streusel all over the top of the batter. Using your fingers or a spoon, gently press some of the streusel a few inches down into the batter. Place on a sheet pan in the middle of your preheated oven. Don't worry if it overflows a bit. It will look cool and still taste great.
The cake is done when you stick a skewer or paring knife about an inch from the center of the cake and it comes out clean. The very center should still be gooey. This takes between 35 and 40 minutes. Since all ovens are different, start checking after about 25 minutes.
Remove from the oven and let it cool for about 30 minutes. Then eat with butter, cream cheese, or a large scoop of vanilla bean ice cream. If you eat it the next day, make sure to warm it up or toast it and then slather it with butter. Freezes beautifully for a few months.
