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.

Best muffins I’ve ever had!
The only changes I made were I used a package of dried blueberries from Aldi and added some freshly ground nutmeg to the dry ingredients. The muffins turned out delicious, but so has every other recipe I've made from LSF. Thank you for sharing!
So yummy! Used fresh organic blueberries.
Thank you!
Oh my goodness! What a delicious way to use some of my ever-growing supply of sourdough discard. The crumb topping really elevates these muffins! Next time, I'll remove the flour-coated blueberries and store them in the freezer until the batter is mixed, then fold them in last. They were breaking open before I was finished mixing, even though they were initially frozen. I did add a couple of tablespoons of water to thin the batter slightly. Will be making these again for sure!
I think they’re great! I should have added more milk than my additional amount as they were still a little dry. Still amazing and yummy!
I made this for my bible study group & some of them thought it was bought at the local bakery. Now that's a compliment! Everyone loved them & there were none left over although some did take some home to their husbands. I used fresh berries but put the in the freezer for about 30 minutes after I washed & dried them & they held up nicely while mixing.
Love your recipes!
Commented on another one that I usually try all recipes exactly as written the first time.
I didn't have everything this time, so I needed to make a couple subs. But I think chemically it worked the same.
I used lime zest instead of lemon... No lemon available.
I didn't have sour cream. So I used a bit of skimmed milk powder, a splash of water and a splash of ACV. Just in the wet mix as components.
Other than that, I followed as written. The zest worked the same and I love lime anyhow, so that part worked. And I think the faux sour 6 cream did its job too.
Omg. They're so good!
Oh yeah. The other thing I did. Lol. I made it into 10 bigger ones vice 12.
But that doesn't change anything really overall. I put my muffin tin right on top of a preheated baking steel. So the thermal mass difference is negligible.
Still got a few tortillas from your recipe I did the other day. They're fantastic as well.
just made my first batch really good will do this again!
Wonderful flavor and texture. Thank you
I've made these twice and they are so delicious! We had a guest for four days and he raved about them so much I sent him home with some. Great recipe!
