Preheat the oven to 350 degrees F. Add mini cupcake liners to two 24-count mini cupcake (or mini muffin) pans and spray them lightly with non-stick spray. (If you don't have two mini cupcake pans, just bake one batch at a time.) There will only be enough batter to partially fill the second pan.
In a large mixing bowl, add the dry ingredients (flour, cocoa powder, baking powder, baking soda, salt and sugar). Mix well with a whisk.
Add all the liquid ingredients, except for the hot water, to a mixing bowl and whisk well.
Make a well in the center of the dry ingredients and add the liquid ingredients. Mix with an electric mixer on medium just until the ingredients are combined. Scrape down the sides of the bowl and mix again for about 5-10 seconds more.
Add the hot water and mix until well combined. Be careful not to over mix. Once it’s combined, stop mixing. You don’t want to mix for several minutes, that’s too long.
Scrape down the sides of the bowl and mix again for about 5-10 seconds.
Fill mini cupcake liners a little over half way up (about ⅔ of the way full). Bake at 350 degrees F for approximately 10-12 minutes. (If using only one pan, cover the remaining batter with plastic wrap and place in the refrigerator until the first batch bakes. Remember there will only be enough batter to partially fill the second pan.)
Set the mini cupcakes on a wire rack to cool for about 5 minutes, then take the cupcakes out of the pan and let them cool completely before adding frosting. (See notes for frosting options with links to those recipes.)

*Dutch-processed cocoa is different from regular unsweetened cocoa powder. See the FAQs in this post to explain why a recipe calls for one and not the other.You can top these cupcakes with chocolate buttercream.
