Preheat the oven to 425 degrees Fahrenheit and place liners into each well of your standard size muffin baking pan. Set aside.
In a medium bowl whisk together flour, sugar, baking powder and salt.
Add the milk, vegetable oil, eggs and vanilla to the dry ingredients. Gently stir until dry ingredients are moistened. Don’t overmix, a few lumps are ok.
In a small mixing bowl toss the diced strawberries with remaining 2 teaspoons of flour, to prevent them from sinking to the bottom of the muffins. Remove ½ cup strawberries and set aside. Add the remaining berries to the batter, fold with a spatula until combined. Do not overmix.
Add batter to muffin cup liners so they are ⅔ full. Sprinkle extra strawberries on top.
Place in preheated oven and bake for 5 minutes. Lower temperature to 350 degrees Fahrenheit and bake an additional 15-18 minutes or until a toothpick inserted into the center of a muffin comes out clean. Baking at the higher heat at first helps create the perfect domed top of your muffin.
Allow to cool on a wire rack before enjoying.
