2½ cups all-purpose flour
1 tablespoon baking powder
1 teaspoon baking soda
¼ teaspoon salt
2 large eggs, at room temperature
1 cup granulated sugar
½ cup unsalted butter, melted
½ teaspoon lemon zest
3 tablespoons lemon juice
1 cup buttermilk or whole milk
1 tablespoon vanilla extract
2 cups fresh blueberries, rinsed and dried (reserve some for topping)

Prepare Streusel: In a medium bowl, mix flour, sugar, and cinnamon. Add melted butter and stir until crumbly. Set aside.
Preheat Oven: Set oven to 400°F (200°C) and adjust rack to just above center. Line muffin tin with tulip liners or spray with baking spray.
Mix Dry Ingredients: In a medium bowl, whisk flour, baking powder, baking soda, and salt.
Mix Wet Ingredients: In a large bowl, whisk eggs and sugar. Add melted butter, lemon zest, lemon juice, buttermilk, and vanilla. Stir to combine.
Combine: Gently fold dry ingredients into the wet mixture until just combined.
Add Blueberries: Toss blueberries with 1 tbsp flour and fold into batter.
Fill & Top: Fill muffin cups to the top. Add reserved blueberries and streusel topping.
Bake: Bake 20–25 minutes or until a toothpick comes out clean.
Cool: Let muffins cool in pan for 5 minutes, then transfer to a wire rack.
Tossing blueberries in flour prevents them from sinking.
Use frozen blueberries without thawing to avoid blue-tinted batter.
Substitute buttermilk with a mix of lemon juice and whole milk.
For taller muffins, use tulip liners and fill to the top.
Muffins freeze well and reheat beautifully.
