15 - 1/3 cup light brown sugar, packed
16 - 1/4 teaspoon ground cinnamon
17 - Pinch of salt
18 - 3 tablespoons unsalted butter, cold and diced
# Step-by-Step:
01 - Preheat oven to 375°F. Line a 12-cup muffin tin with paper liners or grease lightly.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt.
03 - In a large bowl, whisk melted butter and sugar until combined. Add eggs, milk, yogurt, lemon zest, lemon juice, and vanilla. Whisk until smooth.
04 - Gently fold dry ingredients into wet ingredients until just combined. Do not overmix.
05 - Toss blueberries with 1 tablespoon flour to prevent sinking, then fold them gently into the batter.
06 - Divide batter evenly among muffin cups, filling each about 3/4 full.
07 - In a small bowl, combine flour, brown sugar, cinnamon, and salt. Cut in cold butter with a fork or fingers until mixture resembles coarse crumbs.
08 - Sprinkle streusel evenly over muffin batter.
09 - Bake for 20-22 minutes, or until a toothpick inserted in the center comes out clean.
10 - Cool in pan for 5 minutes, then transfer muffins to a wire rack to cool completely.
# Expert Advice:
01 -
- The contrast between that crackly cinnamon streusel and the impossibly tender crumb underneath is the kind of texture harmony that makes people pause mid bite
- Lemon and blueberries are already best friends, but something about the brightness hitting the sweet buttery topping creates this perfect balance that never feels cloying
02 -
- Overmixed muffin batter is the number one way to ruin these, so stop folding the second you no longer see streaks of flour
- Cold butter for streusel is not optional because room temperature butter will just melt into a sandy layer instead of creating those crispy nuggets we all love
03 -
- Room temperature ingredients incorporate more easily, so set everything out about 30 minutes before you start baking
- The muffin cups should be three quarters full, not completely full, or they will overflow and make a mess
