Soft & Fluffy Chocolate Cupcakes

I think my search for the ultimate chocolate cupcake to bake for my kid's classmates on her birthday has ended. Many thanks to unpastiche for sharing this Very Chocolatey Cupcakes. Previously I have tried another of her recipes, which yields very delicious chocolate cupcakes as well. This recipe yields a soft and fluffy chocolate cupcake, while the One-bowl Ultimate Chocolate Cupcakes yields an intense chocolatey flavor and denser (compared to this recipe) cupcake. I absolutely love that recipe, but I may opt for this recipe - actually, I can't decide :D

Been pondering on what exactly contributes to a soft and fluffy cupcake - buttermilk? creaming method? oven temperature?

Here's the list of ingredients from unpastiche. Please refer to her blog for the recipe and method.

Makes 12 cupcakes (Makes 11 for me, size 50x39mm)

60g butter
120g white sugar (I used 100g golden granulated sugar)*
1 egg
125g plain flour
1/2tsp salt
1 tsp baking soda
3/4tsp baking powder (I used 1/2tsp double-acting baking powder)
120g milk
1 drop of vanilla paste
35g unsweetened cocoa powder
100g hot water + 1/2tsp instant coffee granules

*Updated on 7 Nov 2014: not sweet enough with 100g sugar, according to my taste bud :p 120g is just nice :)

my notes:
  • I preheated my oven to 190 degC, then reduced to 175 degC once I put the cupcakes into the oven. Because of that, I removed the cupcakes from the oven after 18 mins as the toothpick inserted came out with only a few crumbs.
  • Cups were filled between 1/2 to 2/3 full.
