This easy Blueberry Muffin recipe creates perfectly moist, fluffy muffins topped with a buttery streusel crumble that rivals any bakery. Made with simple pantry ingredients and fresh or frozen blueberries.
Mix Wet Ingredients: Add oil, egg, buttermilk, and vanilla and mix just until combined. Don't over mix (the batter doesn't need to be "smooth").
2/3 cup oil, 1 large egg, 1/2 cup buttermilk, 1 teaspoon vanilla extract
Add Blueberries: Toss the blueberries in a spoonful of flour. (Optional: helps them not to sink to the bottom of the muffin.) Gently fold blueberries into the batter. Divide batter between muffin cups.
1 cup blueberries
Make Streusel: Make the crumb topping by adding all ingredients to a bowl. Use a fork or pastry blender to cut the butter into the mixture. Sprinkle topping over the tops of each muffin.
Bake for for 17-20 minutes, or until a toothpick inserted in the center comes out clean or with just a few crumbs. Remove muffins from oven and allow to cool in the pan for a few minutes before removing to a wire rack to cool completely.

Notes
Freezing Instructions: Allow the muffins to cool completely, then place them in a freezer bag or container and freeze for up to 3 months. To thaw the frozen muffins, allow them to come to room temperature or place one muffin in the microwave for 15-20 seconds.Adapted from All Recipes
