The light and airy texture of these vanilla cupcakes comes from using oil and water in the batter. And, with just the right amount of sugar, these are not overly sweet. Frosted with custard buttercream, these will be your next favorite cupcakes.
In a bowl, combine flour, baking powder, baking soda, and salt. Set aside.
In the bowl of a stand mixer with the whisk attachment, whip the egg with sugar until light and fluffy.
Gradually add the oil, followed by the buttermilk, water, and vanilla extract.
Lastly, add the flour mix (continue to use the whisk attachment) to ensure you have a smooth batter. (don't overmix).
Divide the batter between 12 to 15 cupcake liners.
Bake for 18 to 20 minutes or until a toothpick inserted in the center comes out clean.
Cool in the pan for 5 minutes, then transfer to a cooling rack to cool completely.
