Mocha muffin

I wanted to try out some mocha muffins, decided to add on some coffee powder to the recipe of easy-make muffins. But the outcome wasn’t as good as it was expected. I used the muffins cups that I have just bought recently, its taller and perhaps longer time to bake. I have filled up to 80% of the cups but seems like it got overflowed again. I think I really have to manage the volume of the batter each cup / tin better the next attempt. But I think normal muffin cups are easier to handle, though they don’t look fanciful. I did not managed to get a dome-shaped and all became flat-top muffins. Hmm although they does not look as good, I am glad my colleagues like it, its moist and soft =) Hope the next round will be more appealing and i really want to get a high dome shaped muffin!
