Customize them with your favorite mix-ins like chocolate chips or nuts for an extra treat. Bake them right away or let the batter rest overnight in the fridge.
1cupof mix ins such as chopped nuts or chocolate chips
Crumble Topping
¾cupall-purpose flour 90 grams
½cupgranulated sugar 100 grams
½teaspooncinnamon
4tablespoonsbutter melted
Instructions
Preheat oven to 350°F. Grease a standard sized muffin tin or line it with paper muffin liners.
Combine the mashed banana, melted butter, oil, sugar, brown sugar, egg, egg yolk, sourdough starter, and vanilla in a bowl. Stir well.
Sift the flour, baking powder, baking soda, cinnamon, and salt over the wet mixture.
Gently fold the dry ingredients into the wet mixture. Fold in any optional extras like nuts or chocolate, if desired.
Scoop the batter into 12 muffin cups. You will get a couple of extra muffins if you add nuts or chocolate.
Make the crumble topping: Blend the flour, sugar, and cinnamon together then stir in the melted butter until you have pea-sized clumps. Sprinkle the tops of the muffins with the streusel mixture.
Bake 18 to 22 minutes or until a toothpick inserted into the middle comes out clean or with only a few crumbs attached.
Notes
You can let the batter sit overnight before baking. If you'd like to do this, cover the bowl and let it sit in the fridge up to 12 hours. When you're ready to bake, proceed with the recipe as directed.
