## Ingredients You’ll Need

Before you begin, gather all the necessary ingredients. Here’s what you’ll need for both the muffin batter and the streusel topping:

**For the Muffin Batter:**

* 2 ½ cups (300g) all-purpose flour
* ¾ cup (150g) granulated sugar
* 2 ½ teaspoons baking powder
* ½ teaspoon baking soda
* ½ teaspoon salt
* ½ cup (1 stick or 113g) unsalted butter, melted and cooled
* 1 cup (240ml) buttermilk (or sour milk: add 1 tablespoon lemon juice or white vinegar to 1 cup milk)
* 2 large eggs
* 1 teaspoon vanilla extract
* 2 cups (250-300g) fresh or frozen blueberries (if using frozen, do not thaw)
* 1 tablespoon all-purpose flour (for tossing with blueberries, optional)

**For the Streusel Topping:**

* ½ cup (60g) all-purpose flour
* ½ cup (100g) granulated sugar
* ¼ cup (50g) packed brown sugar
* ½ teaspoon ground cinnamon
* 6 tablespoons (3 ounces or 85g) cold unsalted butter, cut into small cubes

## Equipment You’ll Need

* Muffin tin (12-cup)
* Muffin liners (optional, but recommended)
* Large mixing bowl
* Medium mixing bowl
* Whisk
* Rubber spatula or wooden spoon
* Measuring cups and spoons
* Ice cream scoop or large spoon (for portioning batter)

## Step-by-Step Instructions

Now, let’s get baking! Follow these detailed instructions to create the perfect Blueberry Streusel Muffins:

### Step 1: Prepare the Streusel Topping

This is the first step as you can keep the streusel in the refrigerator until needed.

1. In a medium mixing bowl, combine the all-purpose flour, granulated sugar, brown sugar, and ground cinnamon.
2. Add the cold, cubed butter to the bowl.
3. Use a pastry blender or your fingertips to cut the butter into the dry ingredients. Work quickly to prevent the butter from melting. The mixture should resemble coarse crumbs with some pea-sized butter pieces.
4. Cover the bowl and place it in the refrigerator while you prepare the muffin batter. This helps the butter stay cold and prevents the streusel from melting during baking.

### Step 2: Preheat Oven and Prepare Muffin Tin

1. Preheat your oven to 375°F (190°C). Make sure your oven rack is positioned in the center of the oven.
2. Line a 12-cup muffin tin with paper liners. Alternatively, you can grease the muffin tin thoroughly with cooking spray.

### Step 3: Combine Dry Ingredients

1. In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, and salt. This ensures that the leavening agents are evenly distributed throughout the batter.

### Step 4: Combine Wet Ingredients

1. In a separate medium mixing bowl, whisk together the melted and cooled butter, buttermilk, eggs, and vanilla extract. Make sure the butter is cooled to prevent it from cooking the eggs.

### Step 5: Combine Wet and Dry Ingredients

1. Pour the wet ingredients into the bowl with the dry ingredients.
2. Use a rubber spatula or wooden spoon to gently fold the wet and dry ingredients together until just combined. Be careful not to overmix the batter. A few lumps are okay; overmixing can result in tough muffins.

### Step 6: Prepare the Blueberries

1. If using frozen blueberries, do not thaw them. Gently toss the blueberries with 1 tablespoon of all-purpose flour (this step is optional but helps prevent the blueberries from sinking to the bottom of the muffins). If using fresh blueberries, you can skip this step or still lightly toss them in flour.

### Step 7: Fold in the Blueberries

1. Gently fold the blueberries into the muffin batter until they are evenly distributed. Be careful not to crush the blueberries.

### Step 8: Fill Muffin Cups

1. Use an ice cream scoop or a large spoon to fill each muffin cup about ¾ full. This will allow the muffins to rise properly without overflowing.

### Step 9: Add Streusel Topping

1. Remove the streusel topping from the refrigerator.
2. Sprinkle a generous amount of streusel topping over the top of each muffin. Don’t be shy; the streusel adds a wonderful flavor and texture.

### Step 10: Bake the Muffins

1. Place the muffin tin in the preheated oven.
2. Bake for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs attached. The muffins should be golden brown on top and spring back lightly when touched.

### Step 11: Cool the Muffins

1. Remove the muffin tin from the oven and let the muffins cool in the tin for 5-10 minutes.
2. Carefully transfer the muffins to a wire rack to cool completely. This prevents the bottoms of the muffins from becoming soggy.

## Tips for Perfect Blueberry Streusel Muffins

* **Don’t Overmix the Batter:** Overmixing develops the gluten in the flour, resulting in tough muffins. Mix the wet and dry ingredients until just combined.
* **Use Cold Butter for the Streusel:** Cold butter is essential for creating a crumbly streusel topping. If the butter is too soft, the streusel will melt and spread instead of forming distinct crumbs.
* **Don’t Thaw Frozen Blueberries:** If using frozen blueberries, add them to the batter while still frozen. This helps prevent them from bleeding into the batter and turning the muffins blue.
* **Toss Blueberries with Flour:** Tossing the blueberries with a tablespoon of flour helps prevent them from sinking to the bottom of the muffins.
* **Use Buttermilk or Sour Cream:** Buttermilk or sour cream adds moisture and tenderness to the muffins. If you don’t have buttermilk, you can make a quick substitute by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk and letting it sit for 5 minutes.
* **Cool Muffins Completely:** Cooling the muffins completely on a wire rack prevents the bottoms from becoming soggy.
* **Use a Cookie Scoop:** A cookie scoop can help ensure that each muffin cup is filled with the same amount of batter, resulting in evenly sized muffins.
* **Check for Doneness:** Use a toothpick to check for doneness. Insert the toothpick into the center of a muffin. If it comes out clean or with a few moist crumbs attached, the muffins are done.
* **Add Lemon Zest:** For an extra burst of flavor, add 1 teaspoon of lemon zest to the muffin batter.
* **Vary the Spices:** Experiment with different spices in the streusel topping. Nutmeg, cardamom, or ginger would all be delicious additions.

## Variations

* **Lemon Blueberry Muffins:** Add 1-2 teaspoons of lemon zest to the muffin batter for a bright, citrusy flavor.
* **Cinnamon Streusel Muffins:** Increase the amount of cinnamon in the streusel topping to 1 teaspoon for a warm, spicy flavor.
* **Nutty Streusel Muffins:** Add ¼ cup of chopped nuts (such as pecans or walnuts) to the streusel topping for extra crunch and flavor.
* **Gluten-Free Blueberry Muffins:** Use a gluten-free all-purpose flour blend in place of the regular all-purpose flour. Be sure to use a blend that contains xanthan gum for best results.
* **Vegan Blueberry Muffins:** Substitute the butter with vegan butter, the buttermilk with plant-based milk mixed with lemon juice or vinegar, and the eggs with flax eggs (1 tablespoon ground flaxseed mixed with 3 tablespoons water per egg).

## Serving Suggestions

* Serve these muffins warm with a pat of butter or a dollop of whipped cream.
* Enjoy them as a quick and easy breakfast with a cup of coffee or tea.
* Pack them in lunchboxes for a delicious and satisfying snack.
* Bring them to a potluck or bake sale.
* Serve them as part of a brunch spread.

## Storage Instructions

* **Room Temperature:** Store the muffins in an airtight container at room temperature for up to 3 days.
* **Refrigerator:** Store the muffins in an airtight container in the refrigerator for up to 5 days.
* **Freezer:** To freeze the muffins, wrap them individually in plastic wrap and then place them in a freezer-safe bag or container. Freeze for up to 2-3 months. To thaw, simply remove a muffin from the freezer and let it thaw at room temperature for about 30 minutes, or microwave it for a few seconds.
