Chocolate Cupcake *half-success-half-failure*

I did something wrong with the cupcake. I know it is suppose to be a "fool-proof" kind of recipe but somehow i think when i half the recipe, it became not very correct (or rather incorrect)! LOL! It is not easy to half like 1-3/4 cup of flour, 3/4 cup of oil..and so forth..very difficult la...lol! But of course the end result is still edible la..more like 'honeycomb' texture than cake texture! But at least i did something right, that for the first time i managed to pipe the whipped cream succesful!! Hurray!!! LOL!
