Blueberry crumble muffins are bakery style muffins you can make at home in under an hour. Each one has a soft, buttery crumb, bursts of juicy blueberries, and a cinnamon brown sugar topping that bakes into a sweet, crunchy crumble.
The batter comes together in two bowls with basic pantry ingredients, and there is no mixer required. Whether you are baking for a weekend breakfast, a school lunchbox, or a brunch table, these blueberry crumble muffins deliver big flavor with very little work.

Why This Blueberry Crumble Muffins Recipe Works
Melted butter and milk keep the crumb moist and tender, while a mix of baking powder and baking soda helps the muffins rise high. Stirring the wet and dry ingredients together only until just combined is the key to a soft texture, because overmixing makes muffins tough.
The topping adds contrast. Brown sugar and cinnamon give a warm, caramel flavor, and a little flour and melted butter turn the mixture into clusters that stay crisp on top of the muffin instead of melting into the batter.
Ingredients for Blueberry Crumble Muffins
For the muffins:
- 2 cups all-purpose flour
- 1/2 cup granulated sugar
- 2 teaspoons baking powder
- 1/2 teaspoon baking soda
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, melted
- 1 cup milk
- 2 large eggs
- 1 teaspoon vanilla extract
- 1 1/2 cups fresh blueberries
For the crumble topping:
- 1/2 cup brown sugar
- 1/4 cup all-purpose flour
- 1 teaspoon ground cinnamon
- 2 tablespoons unsalted butter, melted
Use fresh blueberries and pat them dry before folding them in. Room temperature milk and eggs blend more smoothly into the butter.
How to Make Blueberry Crumble Muffins
1. Prepare the pan.
Preheat the oven to 350 degrees F. Line a 12 cup muffin tin with paper liners.
2. Mix the dry ingredients.
In a large bowl, whisk together 2 cups flour, the granulated sugar, baking powder, baking soda, and salt.
3. Mix the wet ingredients.
In a second bowl, whisk the melted butter, milk, eggs, and vanilla until smooth.
4. Combine and add the berries.
Pour the wet mixture into the dry mixture and stir until just combined. A few small lumps are fine. Gently fold in the blueberries.
5. Make the crumble.
In a small bowl, stir together the brown sugar, 1/4 cup flour, cinnamon, and melted butter until it forms moist crumbs.
6. Fill and top.
Fill each liner about two thirds full with batter, then sprinkle the crumble evenly over the tops.
7. Bake.
Bake for 20 to 25 minutes, until a toothpick inserted in the center comes out clean. Cool in the pan for a few minutes, then move the muffins to a wire rack.
How to Serve Blueberry Crumble Muffins
Serve these muffins warm with a pat of butter or a dusting of powdered sugar. They are lovely with coffee or tea, and they travel well for picnics and school mornings.

How to Store and Reheat Blueberry Crumble Muffins
Store the muffins in an airtight container at room temperature for up to three days. For longer storage, wrap them well and freeze for up to three months. Thaw at room temperature, then warm in a low oven or for a few seconds in the microwave to bring back that fresh baked feel.
Tips and Variations for Blueberry Crumble Muffins
Check that your baking powder is fresh. Extension guidance from Iowa State University notes that baking powder is best used within about six months of opening, which you can read about in this Iowa State AnswerLine article. Old baking powder is a common reason muffins turn out flat.
Toss the berries with a spoonful of the dry mixture before folding them in if you want them to stay evenly spread through the batter. A little lemon zest brightens the flavor. For bigger bakery style tops, fill the liners generously and let the oven do the rest.
Do not overmix the batter. Stir only until the flour disappears, then stop.
Frequently Asked Questions About Blueberry Crumble Muffins
Can I make blueberry crumble muffins ahead?
Yes. Bake them the day before and store them covered at room temperature, or freeze them for later. Warm them briefly before serving.
Can I use frozen blueberries in blueberry crumble muffins?
The recipe was tested with fresh berries. If you use frozen, add them straight from the freezer and fold gently so the batter does not turn purple, and expect a slightly longer bake.
Why did my muffins sink in the middle?
Common causes are overmixing, old baking powder, or opening the oven door too early. Stir gently and keep the door closed until the muffins are set.
Can I use a different milk?
Yes. Any dairy milk works, and plant milks can work in a pinch. Keep the amount the same for a similar texture.
How do I know when the muffins are done?
A toothpick in the center should come out clean, and the tops should look set and lightly golden. Start checking at 20 minutes.
