Preheat the oven to 350°Fahrenheit/175°Celsius. Place 14 cupcake liners in 2 cupcake pans.
In a bowl, whisk together the flour, salt and baking powder.
1 ½ cups cake flour, 2 teaspoons baking powder, ½ teaspoon kosher salt
In a stand mixer fitted with the paddle attachment, or in a large bowl with a handheld mixer, combine the butter, oil and sugar for 2-3 minutes on medium speed until light and fluffy.
¼ cup unsalted butter, ¾ cup granulated sugar, ¼ cup neutral oil
Add the eggs and vanilla extract and mix to combine.
2 large eggs, 3 teaspoons vanilla extract
Mix in the sour cream.
¼ cup sour cream
Add in the dry ingredients and mix until just combine, then slowly pour in the milk.
½ cup whole milk
Using a spoon or a medium cookie scoop, scoop out the cupcake batter into the liners. You want them to be about ¾ full.
Bake for 18-22 minutes. Let the cupcakes cool in the pan for 10 minutes before removing and letting them cool completely on a wire cooling rack.
In a stand mixer fitted with the paddle attachment, or in a large bowl with a hand held mixer, combine the room temperature butter with the confectioners' sugar, salt, vanilla extract and cocoa powder on low speed.
Increase the speed to medium-high and beat for 2-3 minutes, until light and fluffy.
If the frosting isn't as creamy as you would like, add in the heavy cream and beat on medium speed until spreadable.
3-4 tablespoons heavy cream
Frost the cupcakes and enjoy!

Notes
My recipes have been developed and tested in cups and metric grams. I highly recommend using a weighing scale and measuring out your ingredients the metric way.I make sure that all of my ingredients are at room temperature before I start the recipe, so pull out all of the ingredients before you start baking.Butter: I use European style butter in my recipes. This will make your frosting much creamier and richer.Cake Flour: you can swap it out for all-purpose flour but your cupcakes might not be as soft. If you're in the UK, use plain flour. Cake flour in the US is a low protein flour, it isn't flour like self-rising flour! Salt: If you don’t have kosher salt, halve the amount of salt called for in the recipe. 1 teaspoon kosher salt = ½ teaspoon fine salt. Please note, I am using Diamond Crystal kosher salt and not Morton Salt, which is far too salty for this recipe. Sour Cream: You can swap out sour cream for full-fat Greek yogurt or creme fraiche. Storage: Keep in an airtight container in the fridge for up to 5 days. Let it come to room temperature before eating.
