Prep & Cook Time
- Prep Time: 5 minutes
- Cook Time: 35 minutes
- Total Time: 40 minutes
- Servings: 12 muffins
Ingredients
- cooking spray
- 2 ¼ cups all-purpose flour
- 3/4 tsp salt
- 1 tbsp baking powder
- ¼ tsp baking soda
- 1¼ cup granulated sugar
- 1/2 cup unsalted butter (softened)
- 2 large eggs (room temperature)
- 1 tsp pure vanilla powder (use half this amount if you prefer less rich vanilla flavor)
- 2 tsp lemon zest
- ⅔ cup full-fat buttermilk* (room temperature (plus 1 tbsp more if needed))
- 1½ cups blueberries (fresh or frozen (see note), washed and dried)
- ¼ cup turbinado sugar (for topping)
Instructions
- Preheat your oven to 425°F (218°C). Generously grease a standard 12-cup muffin tin with cooking spray or line with parchment paper liners.
- In a medium bowl, whisk together the flour, salt, baking powder, and baking soda. Set aside.
- In a large bowl, using a hand mixer or stand mixer fitted with the paddle attachment, beat the softened butter and granulated sugar together on medium-high speed for 2-3 minutes, until light and fluffy.
- Beat in the eggs one at a time until fully incorporated, then mix in the vanilla powder (use half this amount if you prefer less rich vanilla flavor) and lemon zest.
- With the mixer on low speed, add the dry flour mixture and the buttermilk alternately in three parts, beginning and ending with the dry ingredients. Mix just until the batter is combined and no dry streaks of flour remain. The batter will be thick. If it seems excessively dry, mix in the optional extra tablespoon of buttermilk.
- Gently fold in the washed and dried blueberries using a spatula, being careful not to overmix and crush the berries.
- Divide the batter evenly among the 12 prepared muffin cups, filling them to the top. Generously sprinkle the top of each muffin with the turbinado sugar.
- Bake at 425°F for 5 minutes. Then, without opening the oven door, reduce the temperature to 375°F (190°C) and continue baking for 18-22 minutes, or until a toothpick inserted into the center of a muffin comes out clean or with a few moist crumbs.
- Allow the muffins to cool in the pan for 10 minutes before carefully transferring them to a wire rack to cool completely.
Variations
- Lemon Glaze: For an extra punch of citrus, drizzle cooled muffins with a simple glaze made from powdered sugar and fresh lemon juice.
- Muffin Top Style: For those who love the crown, divide the batter among just 9-10 muffin cups to create oversized, bakery-style muffin tops.
- Streusel Topping: Swap the turbinado sugar for a classic streusel by rubbing together ¼ cup flour, 2 tbsp cold cubed butter, and 2 tbsp brown sugar until crumbly.
- Mini Muffins: Perfect for parties. Portion the batter into a mini muffin tin and reduce the baking time to about 10-12 minutes total.
Tips for Success
- Room Temperature Ingredients: Using room-temperature eggs, buttermilk, and butter is crucial for a smooth, emulsified batter that rises evenly.
- Don’t Overmix: Mix the batter just until the ingredients are combined. Overmixing develops gluten and leads to tough, dense muffins.
- High-Then-Low Baking: The initial high oven heat creates a quick burst of steam, giving the muffins a beautiful, domed top before they set.
- Prevent Sinking Berries: Toss frozen blueberries in 1 tablespoon of the measured flour before folding them into the batter to prevent them from sinking to the bottom.
Storage & Reheating
Store cooled muffins in an airtight container at room temperature for up to 2 days. For longer storage, freeze them for up to 3 months. To reheat, warm a muffin in the microwave for 15-20 seconds or in a 300°F oven for 5-10 minutes until warmed through.
FAQ
Can I use frozen blueberries?
Yes, use them straight from the freezer without thawing to prevent color bleed. Toss them in a little flour from the recipe before folding in, and expect to add 3-5 extra minutes to the baking time.
Can I use milk instead of buttermilk?
The recipe is designed for the acidity of buttermilk, which reacts with the baking soda for lift and tenderness. For a substitute, add 2 tsp of lemon juice or white vinegar to ⅔ cup of regular milk and let it sit for 5 minutes before using.
Why did my muffins turn out dense?
This is usually caused by overmixing the batter or using cold ingredients, which prevents proper aeration. Measure your flour correctly by spooning it into the cup and leveling it off.
My berries sank to the bottom. What happened?
If berries are too wet or the batter is too thin, they can sink. Ensure berries are thoroughly dried after washing. Coating frozen berries in flour also helps anchor them in the batter.
Can I make these muffins ahead of time?
Absolutely. You can prepare the dry and wet ingredients separately the night before. In the morning, combine them and bake. You can also bake and freeze them.
What can I use if I don’t have turbinado sugar?
Coarse sanding sugar or a light sprinkle of regular granulated sugar are good alternatives for that sweet, crunchy top.
