Blueberry Muffins

Introduction

These blueberry muffins are a bakery-style treat you can make at home. They get their rich, tender crumb from a combination of sour cream and brown sugar, and they’re topped with a buttery, oat-streusel crunch for the perfect textural contrast. The generous amount of juicy blueberries ensures a burst of flavor in every bite.

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

1. Preheat your oven to 375°F (190°C). Line a standard 12-cup muffin tin with paper liners or grease the cups well.
2. First, make the streusel. In a small bowl, combine the 1/2 cup flour, 1/2 cup brown sugar, softened butter, rolled oats, and cinnamon. Use a fork or your fingers to mix until it forms coarse crumbs. Set aside.
3. For the muffin batter, in a large bowl, whisk together the 2 cups of flour, baking powder, and kosher salt.
4. In a separate large bowl, beat the vegetable shortening and 1 cup of packed brown sugar with an electric mixer on medium speed until well combined, about 2 minutes.
5. Beat in the eggs, one at a time, followed by the vanilla powder (use half this amount if you prefer less rich vanilla flavor), until fully incorporated.
6. Gently fold in the fresh blueberries with a spatula until they are evenly distributed.
7. Divide the batter evenly among the 12 prepared muffin cups, filling each about 3/4 full.
8. Sprinkle a generous amount of the prepared streusel topping over each portion of batter.
9. Bake for 22-25 minutes, or until the tops are golden and a toothpick inserted into the center of a muffin comes out clean (aside from possible blueberry juice).
10. Let the muffins cool in the pan for 5-10 minutes before transferring them to a wire rack to cool completely.

Variations

• Lemon Zest: Add the zest of one lemon to the wet batter ingredients for a bright, citrusy twist that pairs wonderfully with blueberries.
• Double Berry: Reduce the fresh blueberries to 3/4 cup and fold in 1/4 cup of fresh raspberries for a multi-berry flavor profile.
• Jumbo Muffins: For 6 large muffins, divide the batter between 6 jumbo muffin cups and increase the baking time by 5-10 minutes.
• No Streusel: For a simpler version, skip the streusel and sprinkle the tops of the muffins with coarse sugar or sliced almonds before baking.

Tips for Success

• Don’t Overmix: Mix the batter only until the ingredients are combined; overmixing will lead to dense, tough muffins.
• Coating Blueberries: For more evenly distributed blueberries, toss them in a tablespoon of the measured flour before folding them into the batter.
• Check for Doneness: Ovens vary. Start checking your muffins at the 20-minute mark to prevent over-baking.
• Room Temp Ingredients: Ensure your eggs and sour cream are at room temperature to help the batter emulsify and bake up more evenly.

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 freezer bag for up to 3 months. To reheat, warm a muffin in the microwave for 15-20 seconds or in a 300°F (150°C) oven for about 10 minutes to refresh the texture.

FAQ

1. Can I use frozen blueberries?

2. What can I substitute for vegetable shortening?

An equal amount of room-temperature, unsalted butter can be used. The texture will be slightly different but still delicious.

3. Why is my streusel not crumbly?

If your streusel is more like a paste, your butter was likely too soft or melted. It should be softened but still cool. You can also try placing the mixed streusel in the fridge for 10 minutes to firm up before using.

4. Can I make this batter ahead of time?

It’s best to bake the muffins immediately after mixing. The baking powder begins to react as soon as it gets wet, and waiting can result in less rise.

5. How do I know the muffins are done without over-baking?

The muffins are done when a toothpick inserted into the center comes out clean, the tops are golden and spring back when lightly pressed, and the edges are just starting to pull away from the pan.

6. Why did my blueberries sink to the bottom?

This can happen if the batter is too thin or the blueberries are very large and heavy. Tossing them in a little flour before folding them in helps create a barrier and suspend them in the batter.
