Set your oven to 350°F (175°C), making sure the oven rack sits in the middle.
02 -
Grab a big bowl and mix together the flour, baking soda, cocoa powder, baking powder, sugar, and salt. Sifting is a good idea if you want everything super smooth.
03 -
In another bowl, whisk together vanilla, eggs, oil, and buttermilk for roughly a minute till it’s fully blended.
04 -
Slowly stir the dry mix into your wet ingredients, bit by bit. Add the hot water at the end and mix until it’s smooth. The batter will be very thin—don’t worry, this makes the cupcakes moist!
05 -
Pop paper liners into your cupcake tins and lightly spritz with cooking spray. Pour batter into each liner until it’s about 3/4 full.
06 -
Bake for 18-22 minutes. You’ll know they’re ready when a toothpick poked into one comes out without any wet batter.
07 -
Take the cupcakes out and let them completely cool off before you start frosting them.
08 -
While you wait, mix softened butter and cocoa powder together until smooth. Slowly add powdered sugar and a little milk. Beat until fluffy, adding more milk if it’s too thick.
09 -
Once cool, spread a nice layer of frosting on each cupcake. Add chocolate shavings or your favorite sprinkles to finish it off.
