- ¼ cup vegetable oil – Ensures moistness and tenderness; melted coconut oil or butter makes a lovely substitute.
- 1¾ cups all-purpose flour – Gives structure and bulk; swap for a gluten-free blend if needed.

For the Crumb Topping

Step‑by‑Step Instructions for Blueberry Muffins with Crumb Topping
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This step is crucial for achieving that perfect rise and golden finish on your muffins. While the oven heats, grab a standard muffin tin and prepare it with either non-stick spray or paper liners, ensuring easy removal once your delicious blueberry muffins are baked.
Step 2: Mix Wet Ingredients
In a small mixing bowl, whisk together 1 large egg, ½ cup of milk, and ¼ cup of vegetable oil until well combined. This mixture will provide moisture and richness to your muffins, setting the stage for a fluffy texture. Aim for a smooth blend—this will take only about a minute or two, and the vibrant color of the egg should be fully incorporated.
Step 3: Combine Dry Ingredients
In a larger bowl, mix together 1¾ cups of all-purpose flour, ½ cup of sugar, 2 teaspoons of baking powder, ½ teaspoon of kosher salt, and ¼ teaspoon of cinnamon if desired. Stir these ingredients well with a whisk or spoon until evenly distributed. This dry mix is essential for your blueberry muffins to rise properly and create that delightful fluffy texture everyone loves.
Step 4: Combine Together
Gently pour the wet mixture into the bowl of dry ingredients. Using a spatula or wooden spoon, stir the mixture until just combined, being careful not to overmix. The batter may appear thick, which is what you want for these moist blueberry muffins with crumb topping. It’s okay if a few flour streaks remain; overmixing can lead to denser muffins.
Step 5: Fold in Blueberries
Now it’s time to fold in 1½ cups of fresh or frozen blueberries. Gently incorporate the blueberries into the batter, ensuring they are evenly distributed without crushing them. This process will add bursts of juicy flavor in every bite of your muffins. Remember, if you’re using frozen blueberries, there’s no need to thaw them beforehand; just fold them in straight from the freezer.
Step 6: Prepare Crumb Topping
In a separate bowl, mix together ⅓ cup of sugar, ¼ cup of flour, and 2 tablespoons of unsalted butter at room temperature. Use a fork to combine these ingredients until you achieve a crumbly texture. Ensure you have larger pea-sized pieces, as this will provide a delightful crunch on top of your blueberry muffins.
Step 7: Fill Muffin Tin
Using a spoon, fill the prepared muffin tin with the batter, distributing it evenly. For larger muffins, fill 10 cups to the brim; for smaller portions, use all 12. Try to make sure each cup is filled equally to achieve consistent baking and delightful muffin shapes. The batter should reach the top of each muffin cup for optimal rise.
Step 8: Add Crumb Topping
Sprinkle the crumb topping generously over the muffin batter in each cup. This crunchy layer is crucial for adding that irresistible texture to your blueberry muffins. Aim for an even distribution, giving each muffin a nice rustic look. The crumb topping will caramelize as the muffins bake, enhancing the overall flavor.
Step 9: Bake
Place the muffin tin in your preheated oven and bake for about 20 minutes or until the tops are golden brown and a toothpick inserted into the center comes out clean. Keep an eye on the muffins as they bake—they should rise beautifully and fill your kitchen with a wonderful aroma that signals they’re nearly ready.
Step 10: Cool
Once baked, remove the muffin tin from the oven and let it rest for 5 minutes. This allows the muffins to firm up slightly and makes them easier to handle. After cooling briefly, gently transfer your blueberry muffins to a wire rack to cool completely, ensuring that they don’t get soggy at the bottom.

Blueberry Muffins with Crumb Topping Recipe FAQs
How do I choose the best blueberries for baking?
Absolutely! When selecting blueberries, look for firm, plump berries with a deep blue color. Avoid any with dark spots or blemishes, as these can indicate overripeness. If possible, try to find organic berries; they tend to have more flavor and are less likely to have pesticides. Fresh blueberries are fantastic, but if you go for frozen, there’s no need to thaw them—just fold them into the batter straight from the freezer!
What is the best way to store leftover blueberry muffins?
Very! To store your blueberry muffins and maintain that delightful crumb topping, keep them uncovered at room temperature for up to 2-3 days. If you need to keep them longer (up to a week), place them in an airtight container in the fridge. Just remember, storing in the fridge might soften the crumb topping a bit, so try to enjoy them fresh whenever possible!
Can I freeze blueberry muffins, and how do I do it?
Absolutely! Freezing blueberry muffins is a great way to enjoy them later. Once fully cooled, place them in an airtight container or freezer bag, making sure to remove as much air as possible. They can be frozen for up to 3 months. To reheat, pop a frozen muffin in the microwave for about 15-20 seconds or bake it at 350°F (175°C) for around 10 minutes until warmed through. Enjoy the delightful taste any time!
My muffins came out dense; what did I do wrong?
That can be disappointing! A common culprit for dense muffins is overmixing the batter. When you combine the wet and dry ingredients, make sure to stir gently until just combined—it’s okay if there are a few flour streaks left. Also, be mindful of your oven temperature; baking at a lower temperature can prevent them from rising properly. Ensuring your baking powder is fresh is equally crucial for achieving that perfect fluffiness.
Can I make these blueberry muffins vegan or gluten-free?
Very! To make vegan blueberry muffins, you can substitute the egg with a flax egg (1 tablespoon ground flaxseed mixed with 2.5 tablespoons water, let sit for 5 minutes) and use almond milk in place of regular milk. For a gluten-free option, swap out all-purpose flour for a gluten-free all-purpose blend. Just be aware that texture and flavor might vary slightly, but they can still be delicious!
Are there any dietary considerations I should keep in mind?
Definitely! If you have allergies or are cooking for someone with dietary restrictions, remember that this recipe contains eggs and dairy. Always check your substitute ingredients, and ensure they’re safe for your needs. For pets, it’s generally best to avoid sharing human baked goods with them, as high-sugar treats aren’t ideal for most animals.
