I just made banana nut muffins out of two ripe bananas we had. I used a recipe I modified from Bon Appetit.
It took me a while, and I toasted the nuts and forgot to put them into the batter until I'd scooped three muffins, and I saved too much nuts for the tops, so they're very nutty on top.
Makes 12 muffins.
Preheat oven to 350 degrees. Line muffin cups with papers. Toast nuts in oven for 2-5 minutes, or until toasted.
Whisk together flour, baking powder, baking soda, and salt in a medium bowl.
In a small bowl, mix mashed bananas, milk, and vanilla.
Beat butter in a large bowl until creamy. Gradually beat in sugar. Add eggs one at a time, beating well after each addition. Beat banana mizture and flour mixture alternately into butter mixture in a couple of separate additions. Stir in most of toasted nuts and with a scoop, scoop into muffin pan. Top with remaining nuts.
Bake muffins until tester inserted into a muffin comes out clean, about 30 minutes.
