Preheat oven to 350F. Grease a 12-cup muffin tin and set aside.
Cream sugar, butter, and salt until light and fluffy; about 2 minutes. Add the eggs one at a time and beat well.
Sift flour with the baking soda and gradually add it to the butter mixture.
Mix in the crushed bananas and melted chocolate until the chocolate is well blended.
Gently stir in the walnuts and cherries.
Spoon equal amounts of the batter into the greased muffin tin.
Place in preheated oven and bake for ~ 25 minutes or until a toothpick inserted into the center of a muffin comes out clean. Cool in muffin tin for 10 minutes and then remove to a wire rack to finish cooling.
Notes
The muffins should be eaten in a couple of days or frozen until ready to use. They are delicious reheated or at room temperature!
