- Sourdough Naan – homemade naan is really easy to make and tastes awesome with a slight sourdough tang!
- Sourdough Banana Bread – This delicious sourdough banana bread will quickly be a new favorite. Not quite as cake like as some other banana breads can be, with also a bit more spice due to the lemon zest and ginger, its makes a great winter breakfast – especially warmed and slathered with butter!

Sourdough muffins with blueberries
These muffins are easy to make and a simple (and delicious) way to use your sourdough starter. In this recipe, the sourdough doesn’t give much “rising” power to the recipe – the baking soda is in charge of that still.
In these blueberry muffins, the sourdough starter just gives a slightly sourdough taste to the recipe, so there is no need for any fermentation or rising time. Just dump in your sourdough discard! There is no need to feed it first.

How to make sourdough blueberry muffins
For the full recipe and directions, please scroll down to the recipe card below. This is just a general overview of how to make these muffins so you know the method before you start baking.
- Preheat your oven and liberally grease a muffin pan with either baking spray or with using the butter and flour method.
- In a small bowl, combine the dry ingredients.
- In a large bowl, whisk together the sourdough starter with the other wet ingredients. Really whisk it and make sure the starter is well mixed in, or you will get streaks in your muffins.
- Place the blueberries in a bowl with a few spoonfuls of the flour mixture and toss to coat. This will help them not all sink to the bottom of the muffins.
- Using a spatula or wooden spoon, add the flour mixture to the starter mixture and mix to combine. You are going to have to stir, stir, stir to incorporate the sourdough mixture well.
- Carefully fold in the blueberries coated in flour, as well as any excess flour that is in the bowl the blueberries were in.
- Evenly spoon the batter into the prepared muffin tin. You will barely have enough batter to fill all 12 muffins about ¾ full.
- In a separate medium bowl, mix together the ingredients for the sugar coating, using a fork or your fingers to really mix the butter in.
- Evenly sprinkle the sugar coating over the muffin, being really careful to not get any of the coating on the muffin pan itself.
- Bake for 20 minutes, or until a toothpick inserted in the middle comes out clean.
- Allow to rest for 5-10 min in the pan before removing to a wire rack to cool the rest of the way. Use a knife to run along the edges of each muffin and carefully pull them out of the pan.
- Enjoy!


Can I use other fruit?
You bet! Any kind of berry works really well here! You can use strawberries, blackberries or raspberries. Just make sure you dust them all in the flour mixture before you add them in.
Can I use frozen berries?
Of course! You don’t even need to thaw them, just toss them in the flour to coat and add them in. Frozen berries are less likely to burst during baking, too, so they tend to hold their shape in the muffin.

Notes
You can use frozen blueberies in place of fresh here, or even another kind of fruit.

I never would have guessed that you could make muffins from a sourdough starter, but I am so glad that I did!! These muffins are not as “cakey” as muffins tend to be. They had a bit of a bite to them, and the tanginess from the sourdough starter was wonderful! I also really enjoyed the fantastic streusel crumb layer on top of these. All in all, I was really impressed with these muffins and will be making them a lot!

I used silicone molds. I didn't really get a good browning on them or crisp. Also want sure how much of the sugar coating we were supposed to use. I had a ton leftover. Oh well. I liked that they weren't too sweet anyway. Came out very moist and you can see how the sourdough created pockets just like when you make bread.

These are good! The first time I made them the topping melted all over the oven and made a big mess, so the next time I upped the sugar in the muffin batter to 1/3 cup and then sprinkled sanding sugar mixed with some cinnamon on the top. Definitely a prettier option for me. I made with a mix of blueberries and raspberries, frozen from picking last season, and delicious!
