Step by step instructions
To make the very best, bakery-style muffins you'll need 3 bowls. One for the wet ingredients, one for the dry ingredients, and one for the crumb topping.
- Crumb Topping: Prepare the crumb topping by melting the butter and stirring the flour and sugar in with a fork. Make sure the crumbles are kept a large size, so don't over-mix. Set aside.
- Preheat the oven to 350°F (176°C). Line a 12-count muffin tin with paper liners or grease generously to prevent sticking.
- Dry Ingredients: In a large mixing bowl combine the flour, sugar, baking soda, baking powder, cornstarch, and salt with a fork. Add the blueberries and toss the mixture to coat. Set aside.
- Wet Ingredients: In a medium mixing bowl, whisk the wet ingredients together and then pour into the dry ingredients. Gently stir the mixture until just combined. Don't over-mix the batter.
- Spoon the mixture evenly into a 12-count muffin tin and press the crumble topping over the muffin batter.
- Bake the muffins for 30-35 minutes or until a toothpick inserted into the center comes out clean.
How to make the best crumb topping
The crumb topping might just be the best part of this recipe! The topping covers the muffins with a layer of buttery sweet and crunchy morsels that take these muffins to another level!
To make the crumble, melt the butter and then use a fork to stir the flour and sugar until it looks like wet chunks. Don't break up the chunks too much, you want them to be large!
After spooning the crumb topping into each muffin, gently press the crumbs into the muffin batter. This will make them adhere to the batter and stay put while the muffins are baking.
Either fresh or frozen blueberries can be used in this recipe. I like to freeze fresh blueberries before adding them to the muffin batter because they stay more intact during the baking process.
Greek yogurt can be used in place of the sour cream.
Don't have a kitchen scale to measure flour?
Use the scoop and level technique to measure your flour if you do not have a kitchen scale. To do this, use a spoon to fluff up the flour in the bag. Use a spoon to scoop the flour into a measuring cup until it is heaped on top. Take a butterknife and level off the top. This should give you the most accurate measurement for flour.
Because flour is measured by weight in these recipes, if the flour is scooped straight out of the bag with the measuring cup, there will be more flour than is called for in the recipe.

How to store and freeze
Store the muffins at room temperature, loosely covered, or up to 3 days.
To freeze the muffins, allow them to cool completely. Wrap each one in plastic wrap and insert it into a freezer-safe bag. The muffins can be frozen for up to 3 months.
When you are ready to eat them, allow them to thaw at room temperature. Reheat them in the microwave for 20-second intervals until warm. You can also reheat them in the oven at 300°F (149°C) for 6-10 minutes.

My whole family have fallen in love with these muffins. I make them at least once a week and I change the filling. I’ve done apple (using tinned Apple with cinnamon). Lemon curd (injecting lemon curd into the unbaked dough and adding poppy seeds and lemon zest to the dough. Coffee (adding coffee essence). They’re all amazing.
Shannon Campbell says
These muffins are so easy to make and so delicious. I made them in the evening before bed so we could enjoy one with our coffee in the morning.
The dough felt a bit thick going into the muffin tins but I didn’t add anything, staying true to the recipe and they turned out perfect!
This is the third recipe of yours I have made and they have all been successful!
Nancy S. says
Fairly new to using sourdough starter and not always with success, so I was anxious about trying another recipe. Well, I’m so glad I did! These turned out great and we could hardly wait til they were cool enough to eat. Thanks so much for your post.
Steph Dabrowski says
These were amazing. I followed recipe and consistency was perfect. I did add 1/2 tsp of nutmeg and 1 tsp of cinnamon to the topping crumb. These will be a staple in my house.
Bethann says
Another amazing recipe using discard starter! I got 15 muffins from the recipe.
Prepared as written with two small changes:
1. Used the zest from the whole lemon (we love lemon... 😊).
2. Added about 1/3 cup water because the batter was too dry—I couldn’t stir in all the dry ingredients. I suspect this was because my starter is not as hydrated as yours. Even with the added water the batter was still quite thick, but reading the notes and comments indicated that was the correct density.
The resulting muffins were amazing! The crumb is perfect, and the tart lemon, moist blueberry, and sweet, crunchy topping come together so each bite makes you sigh and say, “Yum!”
I took a plate of the muffins to a friend who has been housebound for almost a year and we had a “socially distanced” chat with tea and muffins (she sat on her porch and I sat 10 feet away on the garden path). She declared the muffins “heavenly!”
Thank you for another recipe that I plan to make many times in the future.
Kathryn says
Amazing! I made this last night and the family loved it. I have to admit, I was a bit lazy and didn't feel like pouring the batter into little muffin cups, so I poured it all in a loaf pan and served slices of it for dessert instead. It turned out perfectly, moist, flavorful and that crumb topping is fabulous. I will definitely be trying the muffins as well, but wanted to let you know how versatile the recipe is. Many thanks for sharing - my girls are already asking when I will be making it again. It's a keeper.
mahnaz says
I made it.
This recipe was very excellent.
I think so that It must be divided to 18 muffins.
I exactly followed you and the muffins are very
beautiful and tasty.
Thank you so much.
Sam says
These were delicious, I made the mistake of not lining the muffin tray so the muffins were hard to remove, but I will know for next time, as I will definitely be making again!
Debra says
I made these at the weekend and they are amazing. My mixture was more cake consistency than a batter but the result was very tasty.
Cheryl says
I made these this evening and was pleased with how simple the recipe was. I didn't have a lemon, so I used orange zest and the muffins were delicious! I had lots of extra topping left over, so I might cut that in half next time. Tasty and easy recipe, thank you!
