Ingredients
List of Ingredients for Blueberry Crumble Muffins
– 1 ½ cups all-purpose flour
– ½ cup granulated sugar
– ½ teaspoon baking powder
– ½ teaspoon baking soda
– ½ teaspoon salt
– 1 large egg
– ½ cup buttermilk (or yogurt)
– ⅓ cup vegetable oil
– 1 teaspoon vanilla extract
– 1 cup fresh or frozen blueberries
– For the crumble topping:
– ½ cup rolled oats
– ¼ cup brown sugar
– ¼ cup all-purpose flour
– ¼ teaspoon cinnamon
– 3 tablespoons cold butter, diced
Description of Key Ingredients
The base of the muffins is all-purpose flour, which gives them a nice, light texture. I use granulated sugar to sweeten the batter just right. Baking powder and baking soda help them rise, making them fluffy. Salt enhances the flavor, balancing the sweetness.
The egg adds richness and binds everything together. Buttermilk, or yogurt, keeps the muffins moist and adds a slight tang. Vegetable oil makes the muffins tender, while vanilla extract gives a lovely aroma. The star of the show is, of course, the blueberries. They add bursts of sweetness and color.
For the crumble topping, rolled oats provide a hearty texture. Brown sugar adds a deep flavor, while flour helps bind it all. A pinch of cinnamon adds warmth, and cold butter creates that delightful crumbly texture.
Substitutions for Dietary Restrictions
If you need a gluten-free option, use a 1:1 gluten-free flour blend in place of all-purpose flour. For a dairy-free option, replace buttermilk with almond milk mixed with a little vinegar. You can swap the egg with a flaxseed meal mixed with water for a vegan alternative.
For lower sugar, you can cut back on granulated sugar and use a sugar substitute. The crumble can be made with coconut oil instead of butter for a dairy-free version. These swaps keep the muffins tasty while meeting different dietary needs.

Step-by-Step Instructions
Preheat the Oven
Start by preheating your oven to 350°F (175°C). This step is key for even cooking. Line a muffin tin with paper liners or grease it lightly. This helps the muffins release easily when baked.
Preparing Dry Ingredients
In a large bowl, mix together 1 ½ cups of all-purpose flour, ½ cup of granulated sugar, ½ teaspoon of baking powder, ½ teaspoon of baking soda, and ½ teaspoon of salt. Stir well until all the dry ingredients are combined. This blend creates a great base for your muffins.
Mixing Wet Ingredients
In a separate bowl, crack 1 large egg and beat it lightly. Add ½ cup of buttermilk (or yogurt), ⅓ cup of vegetable oil, and 1 teaspoon of vanilla extract. Whisk everything together until smooth. This mixture adds moisture to the muffins.
Combining Wet and Dry Ingredients
Make a well in the center of the dry ingredients. Pour the wet mixture into this well. Gently stir with a spoon or spatula until just combined. It’s okay if there are a few lumps; overmixing can make them tough.
Folding in Blueberries
Carefully fold in 1 cup of fresh or frozen blueberries. Use a spatula and be gentle to avoid smashing the berries. This step adds bursts of flavor and color to each muffin.
Making the Crumble Topping
In a small bowl, combine ½ cup of rolled oats, ¼ cup of brown sugar, ¼ cup of all-purpose flour, and ¼ teaspoon of cinnamon. Add 3 tablespoons of cold, diced butter. Mix with your fingers or a fork until it resembles coarse crumbs. This topping gives a sweet crunch.
Filling the Muffin Pan
Divide the muffin batter evenly among the muffin cups, filling each about ¾ full. Sprinkle the crumble topping generously over each muffin. This creates a delightful texture.
Baking the Muffins
Place the muffin tin in your preheated oven. Bake for 18-20 minutes. Check for doneness by inserting a toothpick into the center. It should come out clean when they’re ready.
Cooling and Serving Tips
Let the muffins cool in the pan for about 5 minutes. Then, transfer them to a wire rack to cool completely. Serve warm or at room temperature. Drizzle with honey or maple syrup for extra sweetness, and top with a fresh blueberry for a lovely touch. Enjoy your delicious blueberry crumble muffins!
Tips & Tricks
How to Achieve Perfect Muffins
To make perfect blueberry muffins, follow these steps:
– Use fresh ingredients. Fresh eggs and milk give the best results.
– Don’t overmix the batter. Mix just until combined for light muffins.
– Fill muffin cups to about ¾ full. This helps them rise nicely.
– Bake at 350°F (175°C) for 18-20 minutes. This temperature gives a golden top.
Common Baking Mistakes to Avoid
Many home cooks make these common mistakes:
– Overmixing the batter makes muffins tough. Mix until just combined.
– Not preheating the oven can lead to uneven baking. Always preheat first.
– Skipping the crumble topping removes texture and flavor. Don’t skip it!
Best Practices for Blueberry Handling
Handling blueberries carefully is key. Here are some tips:
– Rinse fresh blueberries gently under cool water. Pat them dry with a towel.
– If using frozen blueberries, do not thaw them. Add them directly to the batter.
– Fold blueberries in gently. This keeps them whole and prevents purple batter.
Following these tips will help you create delicious blueberry crumble muffins every time!
Pro Tips
- Fresh vs. Frozen Blueberries: If using frozen blueberries, do not thaw them before adding to the batter; this prevents them from bleeding into the muffins and keeps the color vibrant.
- Perfectly Light Muffins: Be careful not to overmix the batter when combining wet and dry ingredients. A few lumps are perfectly fine and will result in a fluffier muffin.
- Chill Your Butter: Ensure the butter for the crumble topping is cold before mixing to achieve that desired crumbly texture, giving the muffins a delightful crunch on top.
- Storage Advice: Store the muffins in an airtight container at room temperature for up to 3 days or freeze them for longer storage. Just reheat them in the microwave for a few seconds before serving!

Variations
Different Fruit Options
You can swap blueberries for other fruits. Raspberries or strawberries work great. Chopped peaches add a nice touch too. Mix and match to find your favorite flavors. Every fruit brings its own taste and charm.
Healthy Ingredient Swaps
Want to make these muffins healthier? Try whole wheat flour instead of all-purpose flour. You can use honey or maple syrup instead of granulated sugar. Greek yogurt can replace buttermilk. These swaps keep the muffins tasty while adding nutrition.
Flavored Versions (e.g., lemon zest, almond extract)
Adding lemon zest gives a bright flavor. Just a teaspoon can lift your muffins. For a nutty taste, try almond extract. Mix in a little for a nice twist. These flavors make your muffins extra special and fun!
Storage Info
Best Ways to Store Blueberry Muffins
To keep your blueberry muffins fresh, store them in an airtight container. Place them on the counter if you plan to eat them within 2 days. If you want to keep them longer, consider refrigeration. Just remember, refrigeration can change the texture slightly.
Freezing Instructions
If you want to freeze your muffins, let them cool completely. Wrap each muffin in plastic wrap, then place them in a freezer bag. Remove as much air as possible before sealing. They can last up to 3 months in the freezer.
Reheating Tips for Leftovers
To reheat muffins, use the microwave for about 10-15 seconds. This way, they stay soft and warm. You can also use the oven. Preheat it to 350°F, and heat the muffins for about 5-7 minutes. Enjoy them warm for the best flavor!
FAQs
How do I know when the muffins are done?
You can tell the muffins are done when they turn golden brown. Insert a toothpick in the center. If it comes out clean, they are ready. Bake them for 18-20 minutes for best results.
Can I use frozen blueberries?
Yes, you can use frozen blueberries! They work well in this recipe. Just fold them in gently. They may cause the batter to be a bit purple, but that’s okay. The taste will still be delicious!
What can I substitute for buttermilk?
If you don’t have buttermilk, you can use yogurt instead. Plain yogurt gives a nice flavor. Mix one tablespoon of lemon juice or vinegar with regular milk to make your own buttermilk. Let it sit for five minutes before using.
How long do blueberry muffins last?
Blueberry muffins last for about three days at room temperature. Keep them in an airtight container to stay fresh. You can also store them in the fridge for up to a week.
Can I make the batter in advance?
Yes, you can make the batter in advance! Just cover it and keep it in the fridge for up to 24 hours. When ready to bake, give it a gentle stir and fill your muffin cups. Enjoy fresh muffins anytime!
