In a large bowl, whisk together flour, sugar, salt, and baking powder to create a smooth mixture. This foundation will form the base of your muffins.
Next, combine oil, egg, vanilla extract, lemon juice, and enough milk to reach one cup. This wet mixture will be combined with the dry ingredients later on to form the muffin batter. Make sure that all ingredients are thoroughly mixed together for a balanced flavor profile.
Now it’s time to incorporate the wet ingredients into the dry ones. Combine the oil mixture with the flour mixture, folding the batter gently until the dry ingredients are moistened. It is crucial not to overmix the batter; otherwise, the muffins may become tough and dense. The batter should have a slightly lumpy texture with some traces of dry streaks for optimal texture.
Once the wet and dry ingredients are combined, gently fold in the blueberries. Be gentle while incorporating the blueberries into the batter to prevent them from breaking apart or turning the batter purple. This step adds color and flavor to your muffins, creating a delightful fruity treat.
Next, fill the lined muffin cups with the prepared batter all the way to the top. Overfilling the cups will result in more evenly shaped muffins that rise nicely during baking.
After filling the muffin cups, sprinkle each one generously with the prepared streusel topping. This crumbly mixture adds a delightful contrast in texture and flavor to your muffins. The sweet and buttery topping complements the tangy blueberries perfectly.
Now, it’s time to bake your muffins at 400°F for approximately 20-25 minutes or until a toothpick inserted into the center of a muffin comes out almost clean with a few tender crumbs attached. This ensures that the muffins are fully cooked without becoming dry and overcooked.
Once your muffins are baked to perfection, let them cool completely in the pan before serving. Allowing them to cool helps set the structure of the muffin and makes it easier to remove them from the tin without breaking apart.
To make the streusel topping, combine all the ingredients in a bowl and mix with a fork until the mixture resembles coarse, lumpy sand. Keep this mixture chilled while you prepare the muffins. This ensures that the topping holds its shape and doesn’t melt during baking.
Before starting, set your oven to 400°F and position the rack in the lower middle position for optimal heat distribution. Line standard muffin tins with eight paper liners to make it easier to remove the muffins after baking and for a neat presentation.
In a large bowl, whisk together flour, sugar, salt, and baking powder until they are well combined. This creates a smooth and evenly distributed base for your muffins.
In a 1-cup measuring cup, combine oil, egg, vanilla extract, lemon juice, and enough milk to reach the one-cup mark. Mix these ingredients together thoroughly to ensure a balanced flavor profile in your muffins.
Gradually fold the oil mixture into the flour mixture using a rubber spatula, being careful not to overmix the batter. The batter should remain slightly lumpy with some traces of dry streaks, as this results in a tender and moist muffin texture. Do not overmix the batter or the muffins may become tough.
Once the wet and dry ingredients are combined, gently fold in the blueberries using a spatula. Folding them in gently prevents them from breaking apart or turning the batter purple. This adds color and flavor to your muffins, creating a delightful fruity treat.

After filling the muffin cups, sprinkle each one generously with the prepared streusel topping. This crumbly mixture adds a delightful contrast in texture and flavor to your muffins. The sweet and buttery topping complements the tangy blueberries perfectly.
Place a baking sheet underneath the muffin tin to catch any spillage during baking. Bake the muffins at 400°F for approximately 20-25 minutes or until a toothpick inserted into the center of a muffin comes out almost clean with a few tender crumbs attached. This ensures that the muffins are fully cooked without becoming dry and overcooked.
Once your muffins are baked to perfection, place the muffin pan on a cooling rack and let them cool completely in the pan before serving. Allowing them to cool helps set the structure of the muffin and makes it easier to remove them from the tin without breaking apart.
Finally, make the streusel topping by combining all the ingredients in a bowl and mixing with a fork until the mixture resembles coarse, lumpy sand. Keep this mixture chilled while you prepare the muffins. This ensures that the topping holds its shape and doesn’t melt during baking.
