Preparation Phase & Tools to Use

To make these muffins flawlessly, gather these essential tools:

• Mixing Bowls: One for dry ingredients, one for wet. Keeps things efficient and mess-free.
• Muffin Tin & Liners: Ensures even baking and easy cleanup.
• Measuring Cups & Spoons: Precision is key in baking, especially for that streusel!
• Rubber Spatula: Helps fold ingredients without overmixing.
• Pastry Cutter or Fork: For blending the streusel until crumbly.
• Cooling Rack: Vital for cooling the muffins evenly and preventing sogginess.

Each of these tools plays a role in maintaining structure, texture, and flavor. Skimping on the right equipment can lead to uneven baking or dense muffins.

Preparation Tips

Start by making the streusel topping first; chilling it while preparing the batter helps it hold its crumbly texture during baking. Use fresh or frozen blueberries, but toss them in a bit of flour before folding into the batter to prevent sinking. Avoid overmixing the batter—just combine until you don’t see dry streaks. When scooping into the muffin tin, fill each cup about 3/4 full, then generously top with streusel. Bake in a preheated oven and let them rest in the pan for a few minutes before transferring to a cooling rack. This helps set their shape without making them soggy.

Ingredients for this Perfect Blueberry Streusel Muffins

For the Muffins:

• 1 and 3/4 cups (220g) all-purpose flour
• 1/2 cup (100g) granulated sugar
• 1/4 cup (50g) light brown sugar, packed
• 1/2 teaspoon salt
• 2 teaspoons baking powder
• 1/3 cup (80ml) vegetable oil
• 1 large egg
• 1/3 – 1/2 cup (80–120ml) milk (adjust for batter consistency)
• 1 and 1/2 teaspoons vanilla extract
• 1 cup (150g) fresh or frozen blueberries (if frozen, do not thaw)

For the Streusel Topping:

• 1/3 cup (67g) light brown sugar, packed
• 1 tablespoon granulated sugar
• 1/2 teaspoon ground cinnamon
• 1/4 cup (30g) all-purpose flour
• 1/4 cup (60g) unsalted butter, cold and cubed

Step 1: Prepare the Streusel Topping

In a small bowl, combine the brown sugar, granulated sugar, cinnamon, and flour. Cut in the cold, cubed butter using a pastry cutter or fork until the mixture resembles coarse crumbs. Place in the refrigerator to chill while you prepare the muffin batter.

---

Step 2: Preheat and Prep

Preheat your oven to 375°F (190°C). Line a 12-cup muffin pan with paper liners or lightly grease each cup with non-stick spray.

---

Step 3: Mix Dry Ingredients

In a large mixing bowl, whisk together the flour, granulated sugar, brown sugar, salt, and baking powder. Set aside.

---

Step 4: Combine Wet Ingredients

In another bowl, whisk together the vegetable oil, egg, milk (starting with 1/3 cup), and vanilla extract. Stir until fully combined.

---

Step 5: Bring the Batter Together

Pour the wet mixture into the dry ingredients and stir gently using a rubber spatula until just combined. If the batter feels too thick, add a little more milk a tablespoon at a time.

---

Step 6: Fold in the Blueberries

Toss the blueberries with a teaspoon of flour to prevent sinking, then fold them into the batter carefully without bursting them.

---

Step 7: Fill the Muffin Tins

Divide the batter evenly among the prepared muffin cups, filling each about 3/4 full. Sprinkle a generous amount of chilled streusel topping over each muffin.

---

Step 8: Bake to Perfection

Bake for 20–25 minutes or until the tops are golden and a toothpick inserted in the center comes out clean. Rotate the pan halfway through for even baking.

---

Step 9: Cool and Serve

Let the muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely. Serve warm or at room temperature with a cup of coffee or tea.

Notes

These muffins are incredibly adaptable. You can substitute other berries like raspberries or chopped strawberries if blueberries aren’t available. To give them a citrusy twist, add a teaspoon of lemon zest to the batter. For a slightly denser texture with added fiber, swap 1/4 cup of the all-purpose flour for whole wheat flour. If you’re using frozen blueberries, don’t thaw them beforehand—this prevents bleeding and keeps the color vibrant in the muffins.

Watch Out for These Mistakes While Cooking

• Overmixing the batter: This is a common pitfall and leads to tough, rubbery muffins. Stir just until ingredients are combined.
• Skipping the streusel chill time: Warm streusel melts too quickly and won’t form a proper crumbly topping.
• Overfilling the muffin cups: This can cause batter to spill over and ruin the shape. Stick to 3/4 full.
• Using warm blueberries: If using fresh berries, ensure they’re chilled; warm berries can make the batter runny.
• Opening the oven door too early: Doing so causes the muffins to sink. Wait at least 18 minutes before checking.

Storage Instructions

Store the cooled muffins in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to 5 days. To freeze, individually wrap each muffin and place in a zip-top freezer bag. They can be frozen for up to 2 months. To enjoy, thaw at room temperature or warm in a microwave for 20–30 seconds.

Frequently Asked Questions

How do I prevent my blueberries from sinking to the bottom?

Toss them in a little flour before folding into the batter. It helps suspend them evenly.

Can I use frozen blueberries?

Yes! Just add them straight from the freezer. Do not thaw, or the muffins will turn purple.

What kind of oil should I use?

A neutral oil like vegetable or canola works best. Avoid olive oil as its flavor is too strong.

How do I make these muffins dairy-free?

Use plant-based milk and a vegan butter alternative for the streusel.

Can I use muffin mix and just add streusel?

You can, but homemade batter delivers a far superior texture and flavor.

Why did my muffins come out dry?

They may have been overbaked or not enough liquid was used. Keep an eye on baking time and batter consistency.

Can I double this recipe?

Yes, but bake in two separate batches for even results.

How do I know when they’re done baking?

Insert a toothpick into the center—if it comes out clean or with a few moist crumbs, they’re ready.
