Lemon Blueberry Streusel Muffins

Dive into the delightful taste of Lemon Blueberry Streusel Muffins, where the zesty sweetness of lemon meets the juicy burst of blueberries, all under a crunchy streusel topping. Ideal for breakfast, a snack, or dessert, these muffins offer a tender crumb with bursts of fruity flavors, enhanced by a sweet streusel topping.

Ingredients & Variations:

• Ingredients at Room Temperature: Ensuring ingredients such as butter, sour cream, eggs, and milk are at room temperature helps achieve a smooth batter without lumps.
• Sour Cream: Incorporating sour cream enhances the richness and tenderness of the muffins.
• Lemon: Utilize one whole lemon for zesting and juicing to infuse the muffins with a fresh citrus aroma and flavor.
• Blueberries: Opt for fresh blueberries for optimal taste and texture. If unavailable, frozen blueberries can also be incorporated without thawing to prevent the batter from turning blue.
• Streusel Topping: A simple mixture of flour, sugar, and butter creates a delightful crumbly topping that adds texture and sweetness.
• Optional Glaze: A quick glaze of confectioners’ sugar and water can be drizzled over the cooled muffins for extra sweetness. This step is optional and can be omitted for less sweetness as shown in the pictures.

Can These Be Made Into A Loaf?

Yes! Transform the muffin recipe into a lovely loaf by using an 8 1/2 x 4 1/2-inch (22 x 12 cm) loaf pan and extending the baking time to 65 minutes at the same temperature. Drizzle with the optional glaze after cooling for an added touch of sweetness.

Preparation in Advance:

Prepare the batter a day ahead, leaving out the blueberries, and refrigerate. Just before baking, fold in the blueberries. The batter should be used within 24 hours but can be kept for up to 48 hours if necessary. The streusel topping can also be prepared in advance and stored in the refrigerator for up to a week.

Storing Suggestions:

• Room Temperature: Store the muffins in a single layer in an airtight container, optionally with a paper towel at the bottom to absorb moisture. Enjoy within 2-3 days.
• Refrigerator: Although refrigeration can dry out baked goods, these can be stored in the fridge in an airtight container for up to 5 days. Reheat briefly in the microwave or allow to reach room temperature before serving.
• Freezer: Freeze the cooled muffins in a freezer-safe bag or container for up to 3 months. Label with the date and contents for convenience.
