Why I’ll Love This Recipe

I enjoy the combination of juicy blackberries and warm cinnamon.

The buttery crumble topping adds a delicious crunchy texture.

I get soft, moist muffins with simple pantry ingredients.

I can serve them for breakfast, brunch, or dessert.

They freeze well, making them perfect for meal prep.

Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the muffins:

all-purpose flour
granulated sugar
baking powder
baking soda
salt
eggs
milk
sour cream or plain Greek yogurt
vegetable oil or melted butter
vanilla extract
fresh blackberries

For the cinnamon crumble:

all-purpose flour
brown sugar
ground cinnamon
melted butter

Directions

I preheat the oven to 375°F (190°C) and line or lightly grease a 12-cup muffin pan.
I prepare the cinnamon crumble by mixing the flour, brown sugar, cinnamon, and melted butter until coarse crumbs form, then I set it aside.
I whisk together the flour, baking powder, baking soda, and salt in a large bowl.
In another bowl, I combine the eggs, sugar, milk, sour cream, oil or melted butter, and vanilla until smooth.
I pour the wet ingredients into the dry ingredients and gently stir until just combined.
I carefully fold in the blackberries, trying not to crush them.
I divide the batter evenly among the prepared muffin cups, filling each about three-quarters full.
I sprinkle the cinnamon crumble generously over each muffin.
I bake the muffins for 20–25 minutes, or until a toothpick inserted into the center comes out clean.
I let the muffins cool in the pan for about 5 minutes before transferring them to a wire rack to cool completely.

Variations

I use frozen blackberries when fresh berries aren’t in season, adding them directly from the freezer.
I mix lemon zest into the batter for a bright citrus flavor.
I add chopped pecans or walnuts to the crumble for extra crunch.
I drizzle the cooled muffins with a simple vanilla or lemon glaze.
I substitute blueberries or raspberries for a different berry variation.

Storage/Reheating

I store the muffins in an airtight container at room temperature for up to 3 days.

For longer freshness, I refrigerate them for up to 1 week.

I freeze the cooled muffins in a freezer-safe bag or container for up to 3 months.

To reheat, I warm a muffin in the microwave for 15–20 seconds or in a 300°F (150°C) oven for about 5–10 minutes until heated through.

FAQs

Can I use frozen blackberries?

Yes. I add frozen blackberries directly to the batter without thawing them first to help prevent excess moisture.

How do I keep the blackberries from sinking?

I lightly toss the blackberries with a small amount of flour before folding them into the batter.

Can I make these muffins ahead of time?

Yes. I often bake them a day ahead and store them in an airtight container until I’m ready to serve them.

Why is my crumble topping not crunchy?

I make sure the topping has a coarse, crumbly texture before sprinkling it over the batter, and I avoid overmixing it.

Can I freeze Blackberry Muffins with a Cinnamon Crumble?

Yes. I let the muffins cool completely before freezing them in an airtight container for up to 3 months.
