Follow these easy steps to make your Delicious Classic Vanilla Birthday Cupcakes:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C) and line a 12-cup muffin tin with cupcake liners.
2. Mix Dry Ingredients: In a medium bowl, whisk together the flour, baking powder, and salt.
3. Cream Butter and Sugar: In a large mixing bowl, cream together the softened butter and sugar until light and fluffy.
4. Add Eggs: Beat in the eggs, one at a time, blending well after each addition.
5. Incorporate Vanilla: Mix in the vanilla extract to the butter and egg mixture until fully combined.
6. Combine Mixtures: Gradually add the dry ingredients to the wet ingredients, mixing gently until just combined.
7. Add Milk: Pour in the whole milk, stirring gently until the batter is smooth and well mixed. Avoid over-mixing.
8. Fill Cupcake Liners: Divide the batter evenly among the lined cupcake cups, filling each about two-thirds full.
9. Bake: Place in the preheated oven and bake for 15-18 minutes or until a toothpick inserted in the center comes out clean.
10. Cool the Cupcakes: Once baked, remove the cupcakes from the oven and allow them to cool in the pan for about 10 minutes. Then transfer them to a wire rack to cool completely.
11. Frost The Cupcakes: Once the cupcakes are completely cooled, frost them with your choice of frosting. For a classic touch, use buttercream frosting and add colorful sprinkles.
