I stole Tyler Florence's recipe and changed it up just a skoshe. They turned out wonderful. The two problems I had is that they didn't rise very well, so they were kind of dense, but very moist. I used the Texas sized muffin pan. Inga said they were the best she's ever tasted.
Ingredients (I had to 1.5 times this recipe because I had six fairly large bananas)
2 cups all-purpose flour
1 1/2 teaspoons baking soda
1/2 teaspoon salt
4 overripe bananas
1 cup brown sugar
3/4 cup (1 1/2 sticks) unsalted butter, melted and cooled (I only used two sticks of butter, even at 1.5 time that I should have used. I think I could have cut back a bit from that)
2 eggs
1 teaspoon pure vanilla extract (I used closer to two teaspoons of vanilla & NOT the extract!!)
1/2 cup pecans, chopped (I used walnuts because I prefer walnuts in these.) I also added about a cup and a half of semi-sweet chocolate chips.
Directions
Preheat oven to 375 degrees F and lightly butter 2 muffin tins. (I used a non-stick muffin pan, so no butter needed in the pan. They popped right out.)
In a large bowl, combine the flour, baking soda, and salt; set aside. Mash 2 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 with a rubber spatula. Spoon the batter into the muffin tins to fill them about halfway. (Halfway full took exactly 19 mins in MY oven. Since those didn't rise very well, I filled them almost full, those took another 5-6 mins) Give them a rap on the counter to get any air bubbles out.
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.
All in all, they made 13 Texas sized muffins with the additional ingredients. They came out just simply delicious!!
