Sadly, summer is coming to an end here. Summer vacations are over and finally, the kids are back in school!! You get the exclamation mark, right? Ha!!
If you love chocolate, then you will agree with me - the more the better! It's all about making it more luxurious. This one is an absolute chocolate luxury. One single cupcake is all you need to go to cupcake heaven. It's rich, moist, soft and melts in the mouth. The frosting is rich dark and indulgent. What else can I say? My kids love it and grown-ups love it too! I often use dark chocolate like 80% for myself, which makes it's my weakness.

Ingredients and substitutes
- Chocolate - If you've been on my blog for a while, you know how I feel about chocolate. Guys, it has to be good quality, real chocolate. Not the baking chocolate! Not those cheap chocolate chips!! Use chocolate that you love to eat on its own. I use 70% Callebaut chocolate. And yet, any brand works great as long as it's good quality eating chocolate.
- Brown sugar - I'm using light brown sugar. But you can use dark brown as well. The dark brown gives an extra hint of that molasses and tastes absolutely heavenly. A bit fudgier. I find the light brown is just right and it pleases everyone.
- Sour cream - Adds that little zing and depth of flavor. Don't have sour cream? Just add the same amount of yogurt. BUT, yogurt will reduce the shelf life of the cupcakes. So, if you plan to use them in a day... go with yogurt. Having said that I have also shown you how to make sour cream at home.
