Sourdough Peanut Butter Banana Muffins

Oh, so tender and sweet, these jumbo sourdough peanut butter banana muffins are made with very ripe bananas, sourdough discard and smooth peanut butter. 

My poor neglected sourdough starter has been sitting in the refrigerator for almost six months, just hanging out and hanging on. It had very little hooch on top so I took that as a good sign.

I fed it up without discarding a couple of times and it responded well until finally, I took some out to make these muffins. While the discard doesn’t help with the rise, it surely adds moisture, giving the muffins a lovely texture. 

Sourdough Peanut Butter Banana Muffins

You can use fed or unfed sourdough starter for these muffins though unfed will give them more sourdough flavor. This recipe makes nine jumbo muffins.

Ingredients

2 cups or 250g flour

½ cup, firmly packed, or 100g brown sugar 

½ cup or 100g sugar 

2 teaspoons baking powder

1 teaspoon cinnamon

½ teaspoon fine sea salt

½ teaspoon baking soda

⅔ cup or 150g very ripe banana (peels were brown and speckled)

2 large eggs

½ cup or 113g melted, cooled butter

½ cup or 125g sourdough discard 

¼ cup or 60ml milk

¼ cup, rounded, or 80g smooth peanut butter (with sugar)

1 teaspoon vanilla extract

Method

Preheat your oven to 350°F or 180°C and line a large muffin pan with jumbo paper liners. 

In a large mixing bowl, whisk together the flour, brown sugar, sugar, baking powder, cinnamon, salt and baking soda. 

In another bowl, mash the bananas with a fork and add the eggs and mix.

Add in the butter, sourdough discard, milk, peanut butter and vanilla extract and whisk until smooth. 

Add the wet ingredients to the bowl with the dry ingredients and use a rubber spatula to fold together until just combined.

Divide the batter between your muffin cups. 

Bake for 25-30 minutes in the preheated oven or until a toothpick comes out clean and the muffins are golden brown. 

Remove from the oven and leave to cool for a few minutes on a wire rack. Transfer the muffins to the wire rack. 

These can be eaten warm or cold. Either way, they go great with a cup of coffee in the morning or a cup of tea in the afternoon. 

Enjoy!
