These easy fluffy vanilla cupcakes recipe are soft, light, and full of classic vanilla flavor. The batter comes together quickly, combining simple ingredients like flour, sugar, butter, egg whites, sour cream, and warm milk.Baking produces cupcakes with a tender crumb and a delicate, slightly sweet taste. Once cooled, they can be frosted with creamy vanilla buttercream for an extra layer of indulgence.
Start by heating your oven to 175°C (350°F). Line a 12-cup muffin tin with cupcake liners so the batter doesn’t stick.
Mix Dry Ingredients:
In a large bowl, sift together the flour, sugar, baking powder, baking soda, and salt. Give it a quick stir to combine, and then set aside.
Combine Wet Ingredients:
In a separate bowl, whisk together the melted butter, egg whites, vanilla extract, sour cream, and warm milk until smooth and fully mixed.
Make the Batter:
Slowly add the dry ingredients into the wet mixture. Use a spatula to gently fold everything together until just combined. Be careful not to over mixing can make the cupcakes heavy instead of light and fluffy.
Fill and Bake:
Divide the batter evenly among the 12 cupcake liners. Bake for 20–22 minutes, or until a toothpick inserted in the center comes out clean. Once baked, let them sit in the pan for 5 minutes, then move them to a wire rack to cool completely.
Prepare the Frosting:
Beat the butter until creamy. Gradually add powdered sugar, vanilla, a pinch of salt, and milk or cream. Mix until it’s smooth, fluffy, and easy to spread.
Frost and Decorate:
Once the cupcakes are fully cooled, pipe or spread the frosting on top. Add sprinkles, fruit, or any decoration you like.
