Bakery-Style Blueberry Streusel Muffins

🛒 Ingredients

For the Streusel Topping:

  • 1/2 cup All-purpose flour

  • 1/2 cup Granulated sugar

  • 1/4 cup Unsalted butter (cold and cubed)

  • 1/4 tsp Cinnamon (optional)

For the Muffin Batter:

  • 2 cups All-purpose flour

  • 1/2 cup Granulated sugar

  • 2 tsp Baking powder

  • 1/2 tsp Salt

  • 1/2 cup Whole milk

  • 1/2 cup Sour cream (or Greek yogurt for moisture)

  • 1/2 cup Vegetable oil (or melted butter)

  • 1 Large egg

  • 1 tsp Vanilla extract

  • 1 1/2 cups Fresh or frozen blueberries (do not thaw if frozen)

👩‍🍳 Step-by-Step Instructions

1. Prep the Oven and Pan 🌡️

  • Preheat your oven to 400°F (200°C).

  • Line a 12-cup muffin tin with paper liners (tulip liners work best for that tall, bakery look!).

2. Make the Streusel 🥣

  • In a small bowl, mix the flour, sugar, and cinnamon.

  • Add the cold, cubed butter. Use a fork or your fingers to mash the butter into the dry ingredients until it looks like coarse crumbs. ➡️ Set aside in the fridge.

3. Mix Dry Ingredients 🌾

  • In a large bowl, whisk together the 2 cups flour, sugar, baking powder, and salt.

  • Pro Tip: Toss the blueberries in 1 tablespoon of this flour mixture. This prevents them from sinking to the bottom! ⬇️

4. Mix Wet Ingredients 🥛

  • In a separate medium bowl, whisk the egg, milk, sour cream, oil, and vanilla until smooth.

5. Combine 🔄

  • Gently pour the wet ingredients into the dry ingredients.

  • Use a spatula to fold them together until just combined. ⚠️ Do not overmix; the batter should be thick and slightly lumpy.

  • Gently fold in the floured blueberries.

6. Fill and Top 🥄

  • Scoop the batter into the muffin liners, filling them nearly to the top.

  • Generously sprinkle the chilled streusel topping over each muffin. ➡️ Press down lightly so it sticks.

7. Bake ⏲️

  • Bake for 18–22 minutes, or until a toothpick inserted into the center comes out clean.

  • Let them cool in the pan for 5 minutes before moving to a wire rack.

❓ Common Questions (Q&A)

Q: Why did my muffins come out tough? A: This usually happens from overmixing the batter. Once the flour is added, stir only until the white streaks disappear. 🛑

Q: Can I use frozen berries? A: Yes! Just don’t defrost them first, or they will bleed purple juice into your entire muffin. Add them straight from the freezer. ❄️

Q: How do I get those high, domed tops? A: Starting at a higher temperature (like 400°F) creates a “burst” of steam that lifts the batter quickly before the crust sets. 🚀

Enjoy your baking! 🥧✨
