• servings: 12 servings
• active time: 20 minutes
• total time: 1 hour

Ingredients

1 and 3/4 cups (219g) all-purpose flour (spooned & leveled)

1 teaspoon baking soda

1 teaspoon baking powder

1/2 teaspoon salt

6 Tablespoons (85g) unsalted butter, softened to room temperature

3/4 cup (150g) granulated sugar

1 Tablespoon lemon zest

2 large eggs, at room temperature

1/2 cup (120g) plain Greek yogurt or sour cream, at room temperature*

1 and 1/2 teaspoons pure vanilla extract

3 Tablespoons (45ml) milk*

3 Tablespoons (45ml) fresh lemon juice

1 and 1/2 cups (210g) fresh or frozen blueberries, tossed in 1 Tbsp flour*

1/3 cup (41g) all-purpose flour (spooned & leveled)

2 Tablespoons (25g) packed light or dark brown sugar

1 teaspoon lemon zest

2 Tablespoons (28g) unsalted butter, melted

Directions

Preheat oven to 425°F (218°C). Spray a 12-count muffin pan with nonstick spray or line with cupcake liners. Set aside.

Make the muffins:

Whisk the flour, baking soda, baking powder, and salt together in a medium bowl. Set aside.

In a large bowl using a handheld or stand mixer fitted with a paddle attachment, beat the butter and sugar together on high speed until smooth and creamy, about 2 minutes. Scrape down the sides and bottom of the bowl as needed. Add the lemon zest and beat on medium speed for 1 minute. Add the eggs, yogurt, and vanilla, and beat for 1 minute, then turn up to high speed until the mixture is combined and mostly creamy. (It’s ok if it appears somewhat curdled.) Scrape down the sides and bottom of the bowl as needed.

With the mixer running on low speed, add the dry ingredients, milk, and lemon juice into the wet ingredients and beat until no flour pockets remain. Gently fold in the blueberries. Avoid over-mixing. Batter is thick and fluffy.

Spoon the batter into prepared muffin cups, filling them all the way to the top.

Make the crumb topping:

In a small bowl, use a fork to mix all of the crumb topping ingredients together.

Spoon topping evenly on top of each filled muffin cup, gently pressing it down onto the surface so it sticks. Bake for 5 minutes at 425°F, then, keeping the muffins in the oven, reduce the oven temperature to 350°F (177°C). Bake for an additional 18–19 minutes or until a toothpick inserted in the center comes out clean. The total time these muffins take in the oven is about 23–24 minutes, give or take.

Allow the muffins to cool for 5 minutes in the muffin pan, then transfer to a wire rack to continue cooling. Enjoy warm, or at room temperature.

Muffins stay fresh covered at room temperature for a few days or in the refrigerator for up to 1 week.
