INGREDIENTS:
4 large very ripe bananas mashed
1 egg (beaten)
½ cup sugar (you could use more if you like them REALLY sweet but the bananas are sweet enough)
⅓ cup butter, melted
1½ cups plain all-purpose flour
1 teaspoon baking powder
1 teaspoon baking soda
½ teaspoon salt
Streusel Topping (not necessary! but it's what I made)
½ cup plain flour
¼ cup brown sugar
½ stick (57 grams) cold butter
¼ teaspoon cinnamon
INSTRUCTIONS:
Preheat oven to 350F. Mash bananas and add the lightly beaten egg, sugar and butter and mix well to combine and set aside. In another bowl, add the flour, baking soda, baking powder and salt and whisk well. Add nuts or chocolate or whatever add-ins you want to the dry ingredients. Add dry ingredients to wet ingredients and mix until nearly all the flour has disappeared. Overmixed muffins are tough.Pour into greased cupcake pans (add streusel if you wish) and bake for about 20 minutes. Touch the tops and if they spring back, they're done.
Streusel Topping
Place all ingredients into a food processor and pulse until it's streuselly. (or crumbly) If you don't have a processor, a fork works just fine - or your fingers.
