These triple berry muffins are bursting with fresh fruit. Fluffy, buttery, super moist & incredibly soft — make them with fresh or frozen fruit for the perfect mixed berry muffin. 
I first published this triple berry muffin recipe almost two years ago because the texture is just right — fluffy, buttery and perfectly moist. I recently updated the method and added tips to help you get the best mixed berry muffins every time.
Making muffins has become my Saturday morning ritual — a small way to welcome the weekend. Whether you’re celebrating or just slipping into weekend comfort, muffins are a fantastic start to the day.
These triple berry muffins are exactly that: big, buttery, fluffy, and filled with fruit. They stay moist without feeling greasy, with a soft interior and slightly crisp edges. They’re one of my favorite non-chocolate muffins. 
I usually use blueberries, strawberries and raspberries, but any combination of berries works. You can use fresh or frozen berries — if using frozen, keep them frozen until you fold them into the batter.
A little lemon zest brightens the flavor and balances the sweetness. 
Helpful tips for perfect muffins:
- Bring all ingredients to room temperature before you begin. It makes combining them easier and yields a more even batter.
- Use buttermilk if possible — it helps keep muffins tender, moist and fluffy. If you don’t have buttermilk, add 2 teaspoons of vinegar to 3/4 cup milk to mimic it. Whole milk or 2% gives more flavor than skim.
- Sour cream adds extra moisture and contributes to a tender crumb.
- Stir dry ingredients into the wet ingredients with a large rubber spatula or wooden spoon. You don’t need to overmix — a few lumps are fine. Overmixing can make muffins tough.
- Fill each muffin cavity to the top (about 1/3 cup of batter) to get that classic domed muffin top. The batter is thick, so it won’t overflow.
- If using frozen berries, toss them with 1 tablespoon of flour before folding them into the batter to prevent color bleed and sinking.
- Start baking at a high temperature for the first few minutes (425°F), then lower the oven to 375°F for the remainder of baking. The initial heat jump-starts the rise and creates a nicely golden top.
Here’s how the batter looks in the pan before baking: 
These muffins are loved because they’re light, moist and full of berry flavor. Use your favorite berry mix, or add a handful of chocolate chips for a twist — either way, you’ll have an ideal breakfast treat. 
Triple Berry Muffins
15 mins
18 mins
33 mins
14 muffins
Ingredients
- 1/2 cup unsalted butter, room temperature
- 1 cup granulated sugar
- 2 large eggs, room temperature
- 2 teaspoons vanilla
- 1 tablespoon lemon zest
- 1/4 cup sour cream, room temperature
- 3/4 cups milk, buttermilk preferred*
- 2 and 1/2 cups all purpose flour
- 1 tablespoon baking powder
- 1/4 teaspoon salt
- 2 cups mixed berries, fresh or frozen (if frozen, do not thaw)
- 1 tablespoon flour, if using frozen berries
Instructions
- Preheat the oven to 425°F. Line muffin pans with paper liners or grease and flour two 12-cavity pans. This recipe produced 15 muffins for me.
- In a large bowl, beat the butter and sugar until light and fluffy. Add the eggs and vanilla and beat until combined.
- Turn off the mixer and fold in the lemon zest, sour cream and milk using a rubber spatula or wooden spoon.
- In a separate bowl, whisk together the flour, baking powder and salt. Gently fold the dry ingredients into the wet until nearly combined; the batter will be thick.
- If using frozen berries, toss them with 1 tablespoon flour, then gently fold the berries into the batter.
- Fill each muffin cavity to the top (about 1/3 cup batter). Bake at 425°F for 5 minutes, then reduce the oven temperature to 375°F and bake an additional 10–13 minutes, until the tops are lightly browned and a toothpick comes out clean.
- Let muffins cool in the pan for 5–10 minutes, then transfer to a wire rack to finish cooling.
