3/4cupchopped nuts—walnutspecans, almonds—up to you!
Instructions
Preheat the oven to 350F. Grease a 12-cup muffin tin, or line cups with paper liners.
Beat butter and brown sugar until smooth and blended. Beat in eggs, one by one.
Stir in sourdough starter (or yogurt, if using), mashed banana and vanilla. Add baking soda and baking powder and stir well to combine.
Whisk flour, spices, and salt together and add to the banana mixture.
Stir in blueberries and chopped nuts. Spoon batter into the prepared muffin cups, dividing it evenly.
Bake in the preheated oven for 30 minutes, or until a tester inserted in one of the muffins comes out clean. Serve warm or at room temperature. Store in a tin for up to five days, or freeze for up to three months.
Notes
*If you don’t have sourdough starter, substitute 1/4 cup buttermilk and 1/4 cup all-purpose flour.
