First on my list is "Banana Nut Chocolate Chip Muffins with Streusel Topping"
I have tried several different recipes and I think this one comes out the best.
Banana Nut Muffins with Chocolate Chips
2 cups all-purpose flour
1 1/2 teaspoons baking soda
1/2 teaspoon salt
5 overripe bananas
1 cup brown sugar
3/4 cup (1 1/2 sticks) unsalted butter, melted and cooled
1 teaspoon pure vanilla extract
1/2 cup pecans, chopped
1 package mini chocolate chips
Streusel Topping is optional if you like sweeter muffins
1 stick unsalted butter
1/2 cup flour
1/2 cup brown sugar
Preheat oven to 375 degrees F and lightly butter 2 muffin tins. In a large bowl, combine the flour, baking soda, and salt; set aside. Mash 3 of the bananas with a fork in a small bowl so they still have a bit of texture. With an electric mixer fitted with a wire whisk, whip the remaining bananas and sugar together like you mean it, for a good 3 minutes. Add the melted butter, eggs, and vanilla and beat well, scraping down the sides of the bowl once or twice. Mix in the dry ingredients just until incorporated. Fold in the nuts and the mashed bananas and chocolate chips with a rubber spatula. Spoon the batter into the muffin tins to fill them about halfway. Give them a rap on the counter to get any air bubbles out. Sprinkle a little streusel on top of each muffin. Bake until a toothpick stuck in the muffins comes out clean, 18 to 20 minutes. Let cool for a few minutes before turning the muffins out. Serve warm or at room temperature.
