Ingredients
Method
- First, preheat your oven to 400°F (200°C). Line a 12-cup muffin tin with paper liners or grease it thoroughly.
- In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, and salt. Make sure these ingredients are well combined.
- In a separate medium bowl, whisk the large egg until slightly frothy. Then, whisk in the whole milk, melted and cooled unsalted butter, lemon zest, fresh lemon juice, and vanilla extract. Combine everything thoroughly.
- Pour the wet ingredient mixture into the dry ingredient mixture. With a rubber spatula, gently fold the ingredients together until just combined. Be careful not to overmix; a few lumps are perfectly fine and even desired for tender Lemon Blueberry Muffins.
- Carefully fold in the fresh blueberries. Mix just enough to distribute them evenly throughout the batter. Again, avoid overmixing.
- Divide the batter evenly among the 12 prepared muffin cups, filling each about two-thirds full. For a domed top, you can fill them a little higher.
- Bake for 18-22 minutes, or until the tops are golden brown and a wooden skewer inserted into the center of a muffin comes out clean. Baking at an initially higher temperature helps create those desirable tall, domed tops on your Lemon Blueberry Muffins.
- Allow the Lemon Blueberry Muffins to cool in the muffin tin for 5 minutes before transferring them to a wire rack to cool completely.
Notes
Substitutions & Variations:
Flour: For a gluten-free option, substitute a 1:1 gluten-free baking flour blend (ensure it contains xanthan gum).
Dairy-Free: Replace whole milk with an equal amount of unsweetened almond milk, soy milk, or oat milk. Substitute melted butter with an equal amount of melted coconut oil or a dairy-free butter alternative.
Blueberries: While fresh blueberries are ideal, you can absolutely use frozen blueberries. Do not thaw them! Toss them directly into the flour mixture before adding wet ingredients. This helps prevent them from sinking and bleeding too much color.
Other Berries: Feel free to swap blueberries for raspberries, blackberries, or a mixed berry blend.
Added Spices: A pinch of nutmeg or cardamom can add a warm, complex note.
Streusel Topping: For an extra touch, mix ¼ cup flour, ¼ cup granulated sugar, 2 tablespoons cold butter, and ½ teaspoon cinnamon until crumbly. Sprinkle over the tops before baking.
Lemon Glaze: A simple lemon glaze enhances the lemon flavor. Whisk together ½ cup powdered sugar with 1-2 tablespoons fresh lemon juice until smooth. Drizzle over cooled muffins.
Nuts: Add ¼ cup of chopped walnuts or pecans to the batter for a textural contrast.
Pro Tips for Success:
Don't Overmix: Mix the wet and dry ingredients just until combined; a few lumps are perfectly fine and desired for tender muffins. Overmixing develops gluten, leading to tough, chewy muffins.
Room Temperature Ingredients: Ensure your egg and milk are at room temperature. This allows them to combine more smoothly with other ingredients, creating a more uniform batter and a better texture.
High Initial Heat: Start baking your muffins at 400°F (200°C) for the first 5 minutes, then reduce the heat to 375°F (190°C) for the remainder of the baking time. This initial burst of heat helps the muffins rise quickly, creating those beautiful domed tops.
Toss Blueberries with Flour: Toss fresh or frozen blueberries with a tablespoon of flour before adding them to the batter. This trick helps prevent the blueberries from sinking to the bottom.
Fresh Lemon Zest is Key: Do not skimp on the fresh lemon zest! It carries most of the intense lemon flavor. Use a microplane zester to get only the bright yellow part of the peel, avoiding the bitter white pith.
Fill Muffin Cups Generously: For lovely, tall, domed muffins, fill your muffin cups about two-thirds to three-quarters full.
Check for Doneness: Insert a wooden skewer or toothpick into the center of a muffin. If it comes out clean with no wet batter, your muffins are done. Be careful not to overbake, as this can dry them out.
Storage & Reheating Tips:
Room Temperature: Store cooled muffins in an airtight container at room temperature for up to 2-3 days. Line the bottom of the container with a paper towel and place another on top to absorb excess moisture.
Refrigeration: For longer storage, refrigerate in an airtight container for up to 5-7 days. However, refrigeration can sometimes dry out muffins slightly.
Freezing: Muffins freeze beautifully! Once completely cooled, place them in a single layer on a baking sheet and freeze for about an hour until firm. Then, transfer the frozen muffins to a freezer-safe bag or airtight container. They will last for up to 3 months.
Reheating:
From Room Temperature: Pop a muffin into the microwave for 15-20 seconds, or warm it in a toaster oven at 300°F (150°C) for 5-7 minutes until heated through.
From Frozen: Reheat frozen muffins directly in the microwave for 30-60 seconds, or in a preheated oven at 350°F (175°C) for 10-15 minutes until warmed through. Covering them loosely with foil can help prevent the tops from browning too much.
