Ingredients

This recipe calls for readily available ingredients, with a few staples that elevate the humble muffin to something truly special. The sour cream is key to their incredible tenderness, and fresh blueberries are non-negotiable for that burst of summery flavor.

For the Muffins:

• 8 tablespoons unsalted butter, softened to room temperature

• ½ cup sour cream
• ½ cup whole milk

• ½ teaspoon kosher salt
• 2 ½ cups fresh blueberries

For the Topping:

• ½ teaspoon ground cinnamon

Equipment Needed

A few basic kitchen tools will have you well on your way to muffin bliss:

• Electric mixer (stand or hand mixer)
• Large mixing bowl
• Medium mixing bowl
• Whisk
• Rubber spatula
• 12-cup muffin tin
• Paper muffin liners
• Small bowl for the topping
• Toothpick or skewer for testing doneness
• Wire cooling rack

Instructions

The method for these muffins is straightforward, designed for both novice bakers and seasoned pros. The key is to avoid overmixing, especially once the flour is added, to ensure a tender crumb.

1. Preheat and Prep: Begin by preheating your oven to 350°F (175°C). Line a standard 12-cup muffin tin with paper liners. This step ensures your muffins release easily and keeps your tin clean.

2. Cream Butter and Sugar: In the bowl of an electric mixer fitted with the paddle attachment, combine the softened unsalted butter and 1 cup of granulated sugar. Cream these together on medium-high speed until the mixture is light and fluffy, which should take about 2-3 minutes. This process incorporates air, which is crucial for a light muffin texture.

3. Add Wet Ingredients: With the mixer on low speed, add the eggs one at a time, ensuring each egg is fully incorporated before adding the next. Next, add the pure vanilla extract, the sour cream, and the whole milk. Mix on low speed until just combined. Scrape down the sides of the bowl as needed to ensure everything is evenly incorporated.

4. Combine Dry Ingredients: In a separate medium bowl, sift together the all-purpose flour, baking powder, baking soda, and kosher salt. Sifting helps to aerate the flour and remove any lumps, leading to a more uniform batter.

5. Combine Wet and Dry: With the mixer on low speed, gradually add the flour mixture to the wet ingredients. Beat until just mixed. It’s important not to overmix at this stage; a few streaks of flour are acceptable as they will disappear when folding in the blueberries.

6. Fold in Blueberries: Gently fold in the fresh blueberries using a rubber spatula. Be careful not to mash the blueberries, as this can cause them to bleed into the batter and turn the muffins an undesirable shade of grey. Ensure the batter is well mixed around the blueberries.

7. Prepare the Topping: In a small bowl, stir together the light brown sugar, ground cinnamon, and the remaining 1 tablespoon of granulated sugar. This simple topping will provide a delightful sweet crunch.

8. Fill Muffin Cups: Scoop the batter into the prepared muffin tin, filling each cup just over the top. This will encourage a nice dome on your muffins.

9. First Bake: Place the muffin tin in the preheated oven and bake for 10 minutes.

10. Add Topping and Second Bake: Carefully remove the muffins from the oven. Sprinkle the prepared brown sugar and cinnamon topping evenly over the top of each muffin. Return the muffins to the oven and bake for an additional 10-15 minutes. The muffins are done when they are lightly browned on top and a toothpick or skewer inserted into the middle of a muffin comes out clean.

11. Cool: Once baked, remove the muffin tin from the oven and let the muffins cool in the tin for a few minutes before transferring them to a wire cooling rack to cool completely.

Expert Tips & Tricks

• Room Temperature Ingredients are Key: Ensuring your butter, eggs, sour cream, and milk are at room temperature is crucial for achieving a smooth, emulsified batter and a tender muffin crumb. Cold ingredients can lead to a dense, heavy muffin.
• Don’t Overmix! I cannot stress this enough. Once the flour is added, mix only until just combined. Overmixing develops the gluten in the flour, resulting in tough, rubbery muffins.
• Gentle with the Blueberries: When folding in the blueberries, use a light hand. If you’re worried about them sinking or staining the batter, you can lightly toss them in a tablespoon of the measured flour before adding them to the batter.
• Uniformity in Muffin Size: For even baking, try to fill each muffin cup with roughly the same amount of batter. An ice cream scoop can be a handy tool for this.
• Oven Variations: Ovens can vary in temperature. If you find your muffins are browning too quickly on top before the inside is cooked, you can loosely tent the muffin tin with aluminum foil during the last few minutes of baking.

Serving & Storage Suggestions

These muffins are at their absolute best served warm, perhaps with a generous dollop of butter or a drizzle of honey. They are a perfect accompaniment to a morning cup of coffee or tea, or as a delightful afternoon snack.

For storage, allow the muffins to cool completely before storing them in an airtight container at room temperature for up to 2-3 days. If you live in a very warm or humid climate, refrigerating them might be a better option, though this can slightly affect their texture. To reheat, you can gently warm them in a low oven (around 300°F or 150°C) for a few minutes.

These muffins also freeze beautifully. Once completely cooled, wrap them tightly in plastic wrap and then place them in a freezer-safe bag or container. They will keep well in the freezer for up to 2-3 months. Thaw overnight at room temperature or gently reheat from frozen in the oven.

Variations & Substitutions

While this recipe is fantastic as is, here are a few ideas to customize it:

• Lemon Zest: For a brighter, more vibrant flavor, add the zest of one lemon to the batter along with the vanilla.
• Other Berries: Feel free to substitute or mix in other fresh berries like raspberries or blackberries. Just be mindful of their moisture content.
• Nutty Crunch: For added texture, you could incorporate ¼ cup of chopped walnuts or pecans along with the blueberries.
• Gluten-Free: For a gluten-free version, you can experiment with a good quality all-purpose gluten-free flour blend. You may need to adjust the liquid slightly, as gluten-free flours can absorb moisture differently.

FAQs

Q: Why are my blueberry muffins sometimes grey inside?
A: This often happens when the blueberries are overmixed into the batter, causing their skins to break and release their pigment. Gentle folding is key.

Q: Can I use frozen blueberries instead of fresh?
A: Yes, you can. If using frozen blueberries, do not thaw them completely. Toss them in a little extra flour before adding to the batter to help prevent them from bleeding and sinking. You may also need to add a few extra minutes to the baking time.

Q: My muffins didn’t rise very much. What did I do wrong?
A: This is often due to overmixing the batter, which develops the gluten, or using expired baking powder or baking soda. Ensure your leavening agents are fresh and that you’re mixing the batter only until just combined.

Q: How can I get a really good dome on my muffins?
A: Filling the muffin cups slightly over the top and ensuring your leavening agents are active will help create a nice domed top. Also, baking at the correct temperature is essential.

Q: Can I make these muffins dairy-free?
A: You can try substituting the sour cream with a plain, unsweetened dairy-free yogurt (like coconut or soy-based) and the whole milk with a plant-based milk (like almond or soy milk). The texture might be slightly different, but it should still be delicious.
