Preheat oven to 350°F / 180°C. Line a muffin pan with cupcake liners (12 cavities). You can also line 2 - 3 extra muffin pan cavities with liners, in a second pan (for a total of 14 - 15 cupcakes). Set aside.
In a large heat-proof bowl, add the hot water and cocoa powder. Whisk the two together until you have a smooth paste. Let it sit for a few minutes to allow the cocoa to bloom and for the mixture to cool down a little.
Add the salt, melted butter, sour cream, and mix to combine.
Add both sugars, and whisk to break up and mix the sugars into the batter.
The batter should not be too warm at this stage. If it is, let it sit for a few minutes to cool down a little.
Add both eggs and vanilla extract, and whisk to combine.
Add the flour, baking powder and soda. Gently whisk, just until the flour is mixed through the batter with no lumps. (You can also whisk the flour with the baking soda and baking powder in a separate bowl, and add this to the batter.)
Evenly divide the batter into the cupcake liners (about 3 tbsp, which should be about ⅔ of the way up the cupcake liners). If you have extra cupcake batter, cover it with plastic wrap and keep it in a cool place until the first batch of cupcakes is done and cooling.
Bake the cupcakes in the preheated oven for about 16 - 17 minutes, rotating the pan at the 10 minute mark (if needed). The cupcakes are done when a toothpick inserted into the cupcake comes out clean, and the tops are slightly springy to the touch.
Remove the cupcakes from the oven and let them cool slightly for a couple of minutes. Then carefully remove them from the muffin pan, and place them on a cooling rack to cool completely.
Once cooled, these can be frosted using one of the following recipes.
