Bakery-Style Blueberry Muffins with Lemon-Sugar Streusel

By Sprig Originals ✓ · cooked up in Sprig

These are the tall, craggy, dome-topped blueberry muffins you'd pay four dollars for at a good bakery counter — and the trick is almost entirely technique. Sour cream keeps the crumb tender and moist for days, a short rest lets the flour hydrate so the batter sits up instead of spreading, and a blast of 425°F heat at the start forces the tops to spring into proper domes before the centers set. A brown-sugar streusel and a shower of lemon sugar give you the crunchy lid that makes a muffin feel like dessert rather than breakfast.

Ingredients

• 1/3 cup all-purpose flour
• 3 tbsp light brown sugar, packed
• 2 tbsp granulated sugar
• 1/4 tsp ground cinnamon
• 1 pinch fine sea salt
• 3 tbsp cold unsalted butter, cut into small cubes

• 2 cups all-purpose flour (250 g), plus 1 tbsp for the berries
• 2 tsp baking powder
• 1/4 tsp baking soda
• 3/4 tsp fine sea salt
• 1 cup granulated sugar
• 1 tbsp finely grated lemon zest (from 1 large lemon)
• 1/2 cup unsalted butter, melted and slightly cooled
• 2 large eggs, at room temperature
• 1 cup full-fat sour cream, at room temperature
• 3 tbsp whole milk
• 2 tsp vanilla extract
• 2 1/2 cups blueberries, fresh or frozen (about 12 oz)

• 3 tbsp turbinado or granulated sugar
• 1 tsp finely grated lemon zest

Instructions

1. Make the streusel first: in a small bowl, stir together the 1/3 cup flour, brown sugar, 2 tbsp granulated sugar, cinnamon, and pinch of salt. Add the cold cubed butter and rub it in with your fingertips until you have coarse, pebbly clumps ranging from pea- to almond-size. Refrigerate while you make the batter.
2. In a large bowl, whisk the 2 cups flour, baking powder, baking soda, and 3/4 tsp salt together for a full 20 seconds so the leaveners are evenly distributed.
3. In a second large bowl, rub the 1 cup granulated sugar and 1 tbsp lemon zest together with your fingers until the sugar smells strongly of lemon and looks slightly damp. Whisk in the melted butter, then the eggs one at a time, then the sour cream, milk, and vanilla until completely smooth.
4. Toss the blueberries with the reserved 1 tbsp flour in a bowl until lightly coated — this keeps them suspended in the batter instead of sinking. If using frozen berries, keep them frozen and coat them straight from the freezer.
5. Pour the wet mixture over the dry ingredients and fold with a flexible spatula just until no dry streaks remain — about 12 to 15 strokes. The batter should be thick and a little lumpy. Add the floured blueberries and fold 4 or 5 more times only. Overmixing is what makes tough, tunneled muffins.
6. Cover the bowl and let the batter rest at room temperature for 30 minutes (or refrigerate up to 24 hours). The flour hydrates and the batter thickens noticeably, which is what gives you a tall dome instead of a flat spread.
7. Meanwhile, heat the oven to 425°F with a rack in the center. Line a 12-cup muffin tin with tall paper liners or grease it generously, including the top surface of the pan between the cups. Stir the 3 tbsp turbinado sugar with 1 tsp lemon zest in a small bowl.
8. Divide the rested batter among the 12 cups, filling each one right to the rim and mounding it slightly — a spring-loaded #16 scoop or two heaping soup spoons works well. Do not smooth the tops. Scatter the chilled streusel over each muffin, pressing lightly so it adheres, then sprinkle with the lemon sugar.
9. Bake at 425°F for 8 minutes without opening the door — this initial blast sets the domes. Reduce the oven to 375°F, leaving the muffins inside, and bake another 14 to 18 minutes (18 to 22 if you used frozen berries), until the tops are deep golden and a skewer inserted off-center comes out with no wet batter.
10. Cool in the pan for 5 minutes, then lift the muffins onto a wire rack. Cool at least 15 minutes before eating — the crumb finishes setting as it cools, and molten blueberries are a hazard. Serve slightly warm, plain or with a smear of salted butter.
