Introduction
These buttermilk blueberry muffins deliver bakery-style perfection in your own kitchen. The combination of tangy buttermilk, lemon zest, and a sparkling turbinado sugar topping creates an incredibly tender, moist crumb bursting with juicy blueberries. You’ll find them impossible to resist straight from the oven.
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 coat a standard 12-cup muffin tin with cooking spray or line with paper liners.
- In a medium bowl, whisk together the flour, salt, baking powder, and baking soda. Set aside.
- In a large bowl, use an electric mixer to cream the softened butter and granulated sugar together on medium-high speed until light and fluffy, about 2-3 minutes.
- Beat in the eggs, one at a time, until fully incorporated. Mix in the vanilla powder (use half this amount if you prefer less rich vanilla flavor) and lemon zest.
- Gently fold in the blueberries using a spatula until evenly distributed.
- Divide the batter evenly among the 12 prepared muffin cups, filling them to the top. Sprinkle the turbinado sugar generously over the top of each mound of batter.
- Bake at 425°F for 5 minutes. Then, without opening the door, reduce the oven temperature to 350°F (177°C) and continue baking for 25-30 minutes, or until the tops are golden and 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 transferring them to a wire rack to cool completely.
Variations
- Lemon Blueberry: Add the juice of the zested lemon to the wet ingredients for a more pronounced citrus flavor.
- Streusel Topping: Omit the turbinado sugar and top with a simple crumble made from rubbing together ¼ cup flour, ¼ cup brown sugar, and 2 tbsp cold butter before baking.
- Mini Muffins: Divide the batter into a mini muffin tin and reduce the baking time to 10-14 minutes total, checking for doneness early.
- Muffin Tops: Spread the batter into a “muffin top” pan or shape into flat rounds on a parchment-lined baking sheet for maximum crispy top surface.
Tips for Success
- Room Temperature is Key: Using room-temperature eggs, butter, and buttermilk ensures they emulsify properly, creating a uniform and tender batter.
- Don’t Overmix: Mix the batter until the ingredients are *just* combined. Overmixing develops gluten, leading to tough, dense muffins.
- Preheat Properly: The initial high oven heat is crucial for creating a beautiful, domed top. Make sure your oven is fully preheated before baking.
Storage & Reheating
Store completely cooled muffins in an airtight container at room temperature for up to 3 days. For longer storage, freeze them in a single layer on a baking sheet before transferring to a freezer bag for up to 3 months. To reheat, warm in a 300°F oven for 5-10 minutes or microwave for 15-20 seconds.
FAQ
Can I use frozen blueberries?
Yes, use them directly from the freezer without thawing. Tossing them in a little flour (taken from the recipe’s measured amount) before folding them in helps prevent bleeding and sinking.
What if I don’t have buttermilk?
You can make a quick substitute by adding 2 teaspoons of white vinegar or lemon juice to a liquid measuring cup, then adding enough whole milk to reach the ⅔ cup mark. Let it sit for 5-10 minutes before using.
Why do we start at a high temperature?
The initial blast of high heat causes the leavening agents (baking powder/soda) to react quickly, creating a rapid rise and a beautifully domed muffin top.
My batter seems very thick. Is that correct?
Yes, this is a thick batter, which helps suspend the blueberries and creates a sturdy structure. If it seems unworkably dry, add the optional extra tablespoon of buttermilk.
Can I use muffin liners instead of spray?
Absolutely. Paper liners work perfectly and make for easy cleanup. If using liners, there’s no need to spray the tin.
Why is there both baking powder and baking soda?
The baking powder provides the primary lift. The baking soda is included to react with the acidity of the buttermilk, which enhances browning and adds tenderness.
