Prep & Cook Time
Prep Time: 10 minutes
Cook Time: 25 minutes
Total Time: 35 minutes
Servings: 12 muffins
Ingredients
- 2 cups all-purpose flour
- 1/3 cup vegetable shortening
- 1 cup brown sugar (packed)
- 2 large eggs
- 2 teaspoons baking powder
- 1 teaspoon kosher salt
- 1 cup full-fat sour cream
- 1 teaspoon pure vanilla powder (use half this amount if you prefer less rich vanilla flavor)
- 1 cup fresh blueberries
- Streusel topping:
- 1/2 cup packed brown sugar
- 1/2 cup all-purpose flour
- 1/4 cup (1/2 stick) unsalted butter (softened)
- 1/2 cup rolled oats
- 1/4 teaspoon ground cinnamon
Instructions
- Preheat your oven to 375°F (190°C). Grease a 12-cup muffin tin or line with paper liners.
- Make the streusel topping: In a small bowl, combine the 1/2 cup brown sugar, 1/2 cup flour, softened butter, rolled oats, and cinnamon. Mix with a fork or your fingers until crumbly. Set aside.
- In a large bowl, whisk together the 2 cups flour, baking powder, and kosher salt.
- In a separate bowl, beat the vegetable shortening and 1 cup brown sugar together until creamy. Add the eggs one at a time, beating well after each addition. Mix in the sour cream and vanilla powder (use half this amount if you prefer less rich vanilla flavor) until smooth.
- Fold the fresh blueberries into the batter.
- Divide the batter evenly among the 12 prepared muffin cups.
- Sprinkle the streusel topping generously over each mound of batter.
- Bake for 22-25 minutes, or until a toothpick inserted into the center of a muffin comes out clean.
- Let the muffins cool in the pan for 5 minutes before transferring them to a wire rack to cool completely.
Variations
- For a jumbo bakery-style muffin, bake the batter in 6 larger muffin cups, increasing the bake time by 5-8 minutes.
- Create a double-blueberry version by gently pressing a few extra blueberries onto the top of each muffin before adding the streusel.
- Make a simple glaze by whisking 1 tablespoon of the muffin’s sour cream with a little powdered sugar and drizzle over cooled muffins instead of using streusel.
Tips for Success
- Ensure your shortening and brown sugar are well-creamed for a light, uniform texture.
- The key to tender muffins is to stop mixing as soon as the flour is incorporated—a few lumps are fine.
- For even baking, try to distribute the blueberries and streusel topping uniformly across all muffins.
- If your berries are very juicy, toss them in a tablespoon of the measured flour before folding into the batter to help prevent sinking.
Storage & Reheating
Store muffins in an airtight container at room temperature for up to 2 days, or refrigerate for up to 5 days. For longer storage, freeze for up to 3 months. Reheat in a 300°F oven for 5-10 minutes or in the microwave for 20-30 seconds to restore warmth and softness.
FAQ
Can I use frozen blueberries?
Yes, use frozen blueberries directly without thawing to prevent excess moisture and color bleed into the batter.
What if I don’t have vegetable shortening?
This recipe is designed for shortening, which gives a specific texture. Substituting butter will alter the moisture and density.
Why is sour cream used?
Full-fat sour cream adds richness, moisture, and a slight tang, resulting in a more tender and flavorful muffin compared to milk.
Can I make the streusel topping without oats?
Yes, you can omit the oats. The topping will be a more traditional flour-based streusel, but the oats add a delightful chewy texture.
How do I know when the muffins are done baking?
The tops should be golden, the streusel set, and a toothpick inserted into the center (avoiding a blueberry) should come out clean.
Is kosher salt important?
Yes, its coarser grind disperses differently. If using fine table salt, reduce the amount by about half to avoid over-salting.
