Preheat oven to 350°F (176°C). Line a 12-count muffin pan with cupcake liners. Set aside. (Note, this recipe makes 18 muffins)
In a large bowl, using a fine mesh strainer, sift the flour, baking powder, and salt together. Set aside.
2 ¼ cups flour, 1 teaspoon baking powder, ½ teaspoon table salt
In a large bowl using a whisk or handheld mixer, beat eggs then add the sugar and mix until creamy.
4 large eggs (room temperature), 1 cup white sugar
Add the milk and vanilla. Continue to whisk or beat with handheld mixer.
½ cup milk, 1 tablespoon vanilla extract
Add the oil while whisking at the same time. Mix until every ingredient has integrated.
1 cup vegetable oil
Add the flour a little at the time and whisk each time. Whisk until there are no clumps. Do not over mix.
Using a ¼ dry measuring cup, pour the batter into each liner filling it ¾ to the top.
Bake the muffins for 25 to 30 minutes or until a toothpick inserted in the center comes out clean.
Allow the muffins to cool for 5 minutes in the muffin pan, then transfer to a wire rack to continue cooling.
