There are few things in life better than a toddler with a wooden spoon and a bowl of blueberries. Okay, maybe one thing — the muffins that come out of it. In fact, whole wheat sourdough blueberry muffins are always a favorite in our kitchen.

We are seriously drowning in blueberries right now (in the best possible way). There’s a farm just down the road from us, and let’s just say we may have gotten a little carried away this season. No regrets. The freezer is packed, the fridge has a bowl of them at all times, and now we’re baking with them — which means my little one is basically in heaven. Most often, she’s helping make whole wheat sourdough blueberry muffins with me.

She is my official stirrer, my designated batter-pourer, and honestly, my favorite kitchen helper. There’s something about slowing down and letting her little hands be part of the process that makes even the most ordinary Tuesday morning feel really special. A few extra drips on the counter? Worth it every single time.

These sourdough blueberry muffins have become our go-to. I make them with my whole-wheat sourdough starter, which gives them a little extra depth and that subtle tang that makes them taste like so much more than your average muffin. And the blueberries? I pick them fresh and then pop them in the freezer beforehand — it keeps them firm so they hold their shape in the batter instead of bursting into a purple mess. (Though honestly, purple muffins are still delicious. Ask my toddler.) Whenever we can’t decide what to bake, whole wheat sourdough blueberry muffins always win.

Tips Before You Start

Use a whole-wheat sourdough starter if you have one. It adds a nuttier, more complex flavor that pairs beautifully with the blueberries. Regular starter works great too — you do you.
Fresh-picked and then frozen is the move. I grab blueberries from the farm, spread them out on a sheet pan, and freeze them solid before baking. They keep their shape, don’t bleed into the batter, and taste incredible.
Toss your blueberries in a little flour first. Just a teaspoon or two — it helps them stay suspended in the batter instead of sinking to the bottom.
Don’t overmix. Stir until things are just combined and then put the spoon down. Overmixing makes muffins tough, and we are not here for tough muffins.
Don’t overbake either. The two-temperature baking method below (starting hot, then dropping down) is the secret to that gorgeous domed top and a fluffy, moist center.
Don’t be shy with the blueberries. The original recipe calls for a cup, but I almost always use at least 1½ cups — sometimes more. I want a blueberry in every single bite, and you probably do too.

Ingredients

Dry:

2 cups flour (all-purpose, spelt, or freshly milled wheat)
1 cup sugar
½ teaspoon salt
2 teaspoons baking powder
½ teaspoon baking soda
1 teaspoon cinnamon

Wet:

8 tablespoons butter, melted
2 large eggs, room temperature
½ cup sourdough starter (active or discard)
1 teaspoon vanilla

Add-in:

1 ½ cups blueberries (or more!), fresh-picked and frozen

How to Make Sourdough Blueberry Muffins

Preheat your oven to 425°F and grease or line a muffin tin.
In a medium bowl, whisk together the flour, salt, cinnamon, baking powder, and baking soda. Set aside.
In a large bowl, whisk together the melted butter, sugar, vanilla, and sourdough starter. Add your eggs one at a time and mix until combined.
Gradually add the dry ingredients to the wet and stir until just combined — a few lumps are totally fine. This is a great step to let your toddler help with, by the way. Expect some flour on the counter. It’s part of the charm.
Toss your frozen blueberries in a tiny bit of flour, then gently fold them into the batter.
Spoon the batter into your prepared muffin tin — an ice cream scoop makes this super easy and mess-free (mostly).
Bake at 425°F for 5–6 minutes, then — without opening the oven — drop the temperature to 350°F and bake for another 13–15 minutes. That initial blast of high heat is what gives you that beautiful domed top.
Check with a toothpick — when it comes out clean, they’re done. Let them cool on a wire rack, or eat one immediately straight from the pan. You’ve earned it. For best results, try these steps with whole wheat sourdough blueberry muffins for a wholesome twist.

Long Ferment Option

Want extra gut-health benefits? You can long-ferment this batter overnight. The night before, combine melted butter, sugar, 1 cup of sourdough starter (instead of ½ cup), and flour. Mix well, cover, and let it ferment on the counter for 8–24 hours. By morning, you’ll have the perfect base for whole wheat sourdough blueberry muffins.

The next day, add your salt, baking powder, baking soda, cinnamon, vanilla, and eggs. Mix well — a stand mixer is helpful here since the dough gets quite thick. Fold in your blueberries and bake as directed above.

How to Store and Freeze

Store in an airtight container at room temperature for 3–5 days. To freeze, place in a zip-lock freezer bag for up to 3 months. Reheat in a 350°F oven for 5–10 minutes straight from frozen.

I almost always double this batch — one for now, one for the freezer. Future-you will be very grateful.

Made these? I’d love to hear how they turned out! Leave a comment below and let me know if your little kitchen helper approved.
