I’ve baked more muffin recipes than I can count, but these mixed berry muffins have quickly become one of my favorites. I love that you get a little bit of everything in every bite instead of sticking with just one berry. The buttery cinnamon streusel adds the perfect crunch, and that sweet lemon glaze ties it all together. Every time I make a batch, I tell myself I’ll save a few for breakfast the next day… and somehow they almost always disappear before then!

Ingredient Notes

Bowls with mixed berries, flour, sugar, eggs, butter and milk.

All-purpose flour: This recipe uses flour in both the muffins and streusel topping. Be sure to measure it correctly by spooning it into your measuring cup and leveling it off for the best texture.
Frozen mixed berries: Keep the berries frozen when adding them to the batter. Tossing them with a little flour helps keep them from sinking and prevents too much berry juice from coloring the batter.
Lemon zest: Fresh lemon zest adds a bright pop of flavor and helps balance the sweetness of the berries.
Butter: Melted butter adds rich flavor and keeps these muffins soft and tender.
Eggs: Use room temperature eggs so they mix evenly into the batter.
Milk: For adding a little moisture to the batter.
Sour cream or plain yogurt: Either option adds moisture and helps make the texture extra soft and tender.
Vanilla extract: A little vanilla enhances the flavors of the berries, lemon, and buttery streusel.
Streusel topping: A simple mix of flour, brown sugar, granulated sugar, cinnamon, and melted butter creates a sweet, buttery crumb topping that adds the perfect bakery-style finish.
Lemon glaze: A mix of powdered sugar and fresh lemon juice add bright, sweet flavor.

Recipe Variations

Orange flavor. Replace the lemon zest and juice with orange zest and orange juice for a bright citrus twist.

How to Make Mixed Berry Muffins

Showing the process of mixing ingredients to make muffins.

Whisk together flour, sugars, and cinnamon. Add melted butter and mix with a fork until small crumbs form. Don’t overmix or it will turn into a paste. Set aside.
In a medium bowl, whisk together the dry ingredients (flour, baking powder, baking soda, and salt). Set aside.
In a large bowl, combine granulated sugar and lemon zest. Rub the mixture between your fingers to release the oils.
Add melted butter and eggs. Mix until well combined. Add milk, sour cream and vanilla extract, then mix again until incorporated.

Add half the flour mixture to the wet ingredients and mix until just combined. Toss the frozen berries with the remaining flour, then gently fold them into the batter. A little purple color is normal and will fade as it bakes.
Fill muffin cups almost to the top, then sprinkle with streusel. Bake at 400°F for 20–22 minutes, until golden and a toothpick comes out clean. Cool in the pan for 5 minutes, then transfer to a wire rack. Whisk powdered sugar and lemon juice together, then drizzle over cooled muffins.

Expert Tips

Don’t overmix the batter. Stir the batter just until the flour is incorporated. A few small lumps are okay and will help keep the muffins soft and fluffy.

Coat the berries in flour. Tossing the berries with the remaining flour mixture helps keep them evenly distributed throughout the muffins instead of sinking to the bottom.

Fill the muffin cups generously. For tall, bakery-style muffins, fill the liners almost to the top. Using an ice cream scoop makes this step quick and easy.

Let cool before glazing. Wait until the muffins are completely cooled before adding the lemon glaze so it stays on top instead of melting into the muffins.

Storage Tips

Storing. Store cooled muffins in an airtight container at room temperature for up to 4 days. Be sure the muffins are completely cool before storing to help prevent sogginess.

Freezing. These muffins freeze well for up to 3 months. Wrap them tightly in plastic wrap and place them in a freezer-safe container or bag. Thaw at room temperature or warm in the microwave before serving.

Recipe FAQ

Can I use fresh berries instead of frozen?

Yes! Fresh berries will work well in this recipe. If using larger berries, like strawberries, chop them into smaller pieces so they are evenly distributed throughout the muffins.

Can I make these muffins without the streusel topping?

Absolutely. The muffins are still delicious without the streusel, but the topping adds a sweet, buttery crunch that makes them extra special.

How do I keep the muffins from becoming dense?

The biggest key is not overmixing the batter. Stir just until the ingredients are combined, overmixing can make muffins tough instead of light and fluffy.
