Ingredients

Why this recipe works

The method here is simple but effective. Mixing the wet ingredients first, then folding in the dry ingredients, creates a thick batter that holds the blueberries in place and bakes up with a tender crumb.

The high oven temperature and generous filling of the muffin cups help create that coveted domed top. The crumb topping, made with a mix of sugars and cornstarch, bakes into crisp, buttery clusters that contrast beautifully with the soft muffin.

Using melted butter instead of softened butter means no waiting for it to come to room temperature, and it also contributes to a more tender texture. The cornstarch in the topping helps absorb moisture, keeping the streusel crunchy even after baking.

Folding the blueberries gently into the batter prevents them from sinking to the bottom, ensuring every muffin has a generous distribution of fruit. This recipe is designed to be reliable and delicious, with every step contributing to the final result.

Notes and substitutions

For the best flavor, use fresh lemon zest and squeeze the lemon juice for another use. The zest provides bright, aromatic oils that are essential here. When choosing blueberries, look for plump, firm berries; frozen berries work well too, and they should be added straight from the freezer to prevent the batter from turning purple. If using frozen, do not thaw them before folding in.

The crumb topping can be made ahead and stored in the refrigerator for up to 3 days, or frozen for up to a month. This makes it easy to assemble the muffins quickly on busy mornings. For a dairy-free version, substitute the butter with a plant-based butter and use your favorite non-dairy milk. The texture will still be delicious, though the crumb may be slightly softer.

• fresh blueberries: frozen blueberries (do not thaw before adding to the batter)
• unsalted butter: salted butter (reduce the added salt to 1/4 teaspoon)
• whole milk: 2% or skim milk, or a non-dairy milk like almond or oat milk
