Notes:
Why buttermilk?
The use of buttermilk in cakes and cupcakes helps the cake to get a moist and airy texture, in most of my recipes I use buttermilk and indeed you can feel the difference.
What can we use instead of buttermilk?
If you cannot find buttermilk in your country, you can make a home buttermilk: stir 1 cup (240ml) of whole milk with 1 tablespoon of vinegar or lemon juice, let stand for 10 minutes before use. If you still prefer not to use buttermilk you can use whole milk instead.
