Ingredients for Sparkling Jumbo Blueberry Muffins
- 3 cups (375g) all-purpose flour (spooned & leveled)
- 3 teaspoons baking powder
- 1/4 teaspoon baking soda
- 1/2 teaspoon ground cinnamon (optional)
- 1/2 teaspoon salt
- 5 Tablespoons (71g) unsalted butter, melted and slightly cooled
- 1/3 cup (80ml) vegetable oil
- 1 cup (200g) granulated sugar
- 2 large eggs, at room temperature
- 1/3 cup (80g) sour cream or yogurt, at room temperature*
- 1 cup (240ml) milk, at room temperature*
- 1 teaspoon pure vanilla extract
- 1 and 1/2 cups (210g) fresh or frozen blueberries (do not thaw)
- Optional: coarse sugar for sprinkling
Step-by-Step Instructions
- Preheat oven to 425°F (218°C). Generously grease a jumbo 6-count muffin pan with butter or nonstick spray (nonstick spray recommended) or line with muffin liners. Set aside.
- In a large bowl, whisk together the flour, baking powder, baking soda, salt, and cinnamon (if using). Set aside.
- In another bowl, whisk the melted butter, oil, sugar, and eggs until combined. Then whisk in the sour cream, milk, and vanilla extract. The mixture will be pale yellow.
- Pour the wet ingredients into the dry ingredients and fold together with a silicone spatula or wooden spoon until completely combined. Use a whisk to rid any large lumps of flour, if needed. Avoid overmixing. The batter will be thick.
- Gently fold in the blueberries until evenly distributed.
- Divide the batter between each muffin cup, filling all the way to the top. Sprinkle with coarse sugar for added crunch (recommended!).
- Bake at 425°F for 5 minutes, then, keeping the muffins in the oven, reduce the oven temperature to 350°F (177°C) and continue to bake for 25-30 minutes or until the tops are lightly golden brown and centers are set. Test for doneness by inserting a toothpick into the center of a muffin; if it comes out clean, the muffins are done.
- Allow to cool for 10 minutes in the pan before serving.
- Store leftovers covered at room temperature for 5 days, in the refrigerator for 1 week, or freeze for up to 3 months. Thaw in the refrigerator or on the counter.
Perfect Pairings: Serving Suggestions
These Sparkling Jumbo Blueberry Muffins are a treat on their own, but they shine even brighter with a few accompaniments. Serve them warm with a dollop of whipped cream or a drizzle of honey for extra indulgence. Pair with a cup of hot coffee or tea for a cozy breakfast or afternoon snack. For a brunch spread, add a side of fresh fruit or yogurt to balance the sweetness.
Storage and Reheating Tips
To keep your muffins fresh, store them in an airtight container at room temperature for up to 5 days or in the refrigerator for up to 1 week. For longer storage, freeze them in a freezer-safe bag for up to 3 months. To reheat, pop them in the microwave for 10-15 seconds or warm them in a 300°F (150°C) oven for 5-10 minutes. They’ll taste just like they’re fresh out of the oven!
Recipe Variations to Try
Feel free to get creative with this recipe! Swap the blueberries for raspberries, chopped strawberries, or even chocolate chips for a different twist. For a nutty flavor, fold in chopped walnuts or pecans. If you’re out of sour cream, Greek yogurt works just as well. You can also make these muffins gluten-free by using a 1:1 gluten-free flour blend.
Time-Saving Tips for Busy Bakers
To streamline the process, measure out all your ingredients before you start—this is called mise en place. Use a large ice cream scoop to portion the batter evenly into the muffin cups. If you’re short on time, skip the coarse sugar topping—the muffins will still be delicious. For even faster prep, use frozen blueberries (no need to thaw!) to save on washing and chopping.
Equipment Guidance for Best Results
For jumbo muffins, a 6-count jumbo muffin pan is essential. If you don’t have one, you can use a standard 12-count pan—just reduce the baking time by 5-7 minutes. A silicone spatula is perfect for folding in the blueberries without crushing them. And don’t forget a toothpick to test for doneness—it’s the easiest way to ensure your muffins are perfectly baked.
