Blueberry crumble muffins are a delightful treat that combines the sweetness of fresh blueberries with a crunchy, buttery crumble topping.

Perfect for breakfast or as a snack, these muffins are easy to make and sure to impress. Here’s a simple recipe to whip up a batch of these delicious muffins.
Ingredients
For the Muffins:
- 3/4 cup granulated sugar (150 grams)
- 1/2 cup 2% milk (4 ounces)
- 1/2 cup vegetable oil (4 ounces)
- 1 large egg
- 1 teaspoon vanilla extract (4 grams)
- 2 cups all-purpose flour (260 grams)
- 2 teaspoons baking powder (6 grams)
- 1/4 teaspoon salt
- 2 cups fresh blueberries (12 ounces)

For the Crumble Topping:
- 1/4 cup granulated sugar (50 grams)
- 1/4 cup all-purpose flour (33 grams)
- 2 tablespoons salted butter, softened (28 grams)
Instructions
- Preheat the Oven: Preheat your oven to 425°F (220°C). Line a muffin pan with 12 paper liners.
- Prepare the Muffin Batter:
- In a large bowl, whisk together the sugar, milk, oil, egg, and vanilla until well combined.
- In another bowl, mix together the flour, baking powder, and salt.
- Gradually fold the dry ingredients into the wet mixture until just combined. Be careful not to overmix; it’s okay if there are a few lumps.
- Gently fold in the fresh blueberries.
- Make the Crumble Topping:
- In a small bowl, combine the sugar, flour, and softened butter. Use your fingers or a fork to mix until crumbly, with some larger pieces remaining.
- Assemble the Muffins:
- Spoon the muffin batter into the prepared muffin tins, filling each cup about two-thirds full.
- Sprinkle the crumble topping generously over each muffin.
- Bake: Bake in the preheated oven for about 18-20 minutes, or until a toothpick inserted in the center comes out clean and the tops are golden brown.
- Cool and Enjoy: Allow the muffins to cool in the pan for about 5 minutes before transferring them to a wire rack. These muffins are best enjoyed warm but can be stored in an airtight container for several days.

Tips for Success
- For extra flavor, consider adding a teaspoon of lemon zest to the muffin batter.
- If using frozen blueberries, do not thaw them before adding to the batter; this will help prevent them from bleeding into the mixture.
- To make these muffins even more indulgent, you can add a sprinkle of cinnamon to the crumble topping.
These blueberry crumble muffins are not only easy to make but also provide a burst of flavor in every bite. Perfect for any occasion, they can be served at breakfast or as a sweet treat throughout the day! Enjoy your baking!
