Mixed Berries Streusel Muffin
intro
Tender, moist muffins bursting with juicy summer mixed berries, topped with buttery cinnamon streusel—perfect for portable picnic treats or quick light breakfasts.
Ingredients
Steps
Preheat your oven to 190°C (375°F) with a rack positioned in the middle. Line a 12-cup standard muffin tin with paper liners, or grease each cup with nonstick cooking spray. Make the streusel topping: in a small bowl, combine 50g all-purpose flour, 50g packed light brown sugar, and 1/2 teaspoon ground cinnamon. Add 45g cold cubed unsalted butter, and use your fingertips to rub the butter into the dry ingredients until the mixture forms coarse, pea-sized crumbs. Set the streusel in the refrigerator to chill while you prepare the muffin batter.
In a large mixing bowl, whisk together 240g all-purpose flour, 100g granulated sugar, 2 teaspoons baking powder, and 1/2 teaspoon fine sea salt for 30 seconds until fully combined, with no visible clumps of baking powder remaining.
In a separate medium bowl, whisk together 180ml room-temperature whole milk, 2 large room-temperature eggs, 85g cooled melted unsalted butter, and 1 teaspoon pure vanilla extract until completely smooth. Pour the wet ingredient mixture into the bowl of dry ingredients, and use a rubber spatula to fold gently just until no dry flour streaks remain. Stop mixing as soon as the batter comes together; it will be thick and slightly lumpy, and overmixing will cause tough muffins.
Toss 225g mixed fresh berries with 1 teaspoon all-purpose flour until lightly coated (this prevents berries from sinking during baking). Gently fold 3/4 of the floured berries into the muffin batter, taking care not to crush delicate raspberries as you mix to avoid excess purple streaking in the batter.
Divide the batter evenly between the 12 prepared muffin cups, filling each cup roughly 2/3 full (do not overfill, as muffins will rise and dome while baking). Scatter the remaining 1/4 of the floured berries over the top of the batter in each cup, then sprinkle the chilled streusel crumbs evenly over every muffin, pressing the crumbs very lightly to help them adhere to the batter.
Bake the muffins at 190°C (375°F) for 18 to 22 minutes, or until a toothpick inserted into the center of a middle-cup muffin comes out with 1 to 2 moist crumbs attached (it should not have wet batter, nor come out completely clean, which indicates overbaking). Let the muffins cool in the tin for 5 minutes, then transfer them to a wire rack to cool for an additional 10 minutes before serving.
Tips
2.Coating berries in a thin dusting of flour before folding them into the batter prevents the fruit from sinking to the bottom of the muffin cups and stops excess berry juice from turning the entire batter purple.
3.If using frozen mixed berries, do not thaw them first: toss frozen berries directly in the flour coating and fold into the batter, adding 2 to 3 minutes to the total bake time to account for the colder fruit.
OMG these muffins are SO good! I baked a batch this morning for my kids’ after-school snack and they devoured half the pan before I even packed the rest up for the week. The streusel topping is perfectly crispy and not too sweet, and the burst of berries in every bite is chef’s kiss. Super easy to throw together too, even on a busy weekday morning!
Total game changer for work potlucks! I brought these in for our team breakfast yesterday and every single muffin was gone in 10 minutes. The only reason I’m not giving 5 stars is I wish the streusel recipe made a little more — I’m a topping fiend so I ended up doubling it on my first go. 10/10 will make again, though!
Perfect for my weekly meal prep! I bake a batch of these every Sunday to grab for quick breakfasts on my commute, and they hold up so well in the fridge all week. They don’t get soggy at all, and the berry flavor stays bright even after 4-5 days stored in an airtight container. Easy enough that I don’t stress about fitting baking into my Sunday prep routine!
I’m literally terrible at baking — I burn cookies, my cakes always sink, I can never get quick breads to cook all the way through. But these muffins came out PERFECT on my first try! The instructions were so straightforward, 40 minutes total cook time was exactly right, no raw middle, no burnt edges. My roommate thought I bought them from a fancy bakery, I’m so proud!
Really solid muffin recipe! I swapped the all-purpose flour for a 1:1 gluten free baking blend to accommodate my celiac, and they turned out so tasty. The only tiny issue was my streusel got a little more crumbly than I expected, but that might be because of the flour swap. My whole family loved them at our Sunday dinner, even my picky teen!
