Banana Carrot Muffin with Cream Cheese Icing

I'm on the roll with muffin making. Did my first icing today. Cream Cheese. I went a step more adventurous and sprinkle some cadbury cocoa powder. Frankly, I like with the spread of cream cheese icing on top minus the cocoa powder. It kinda made the muffins all browny. I may try my hands on coloured icing next time. Though I'm not too keen in putting colourings into my food. I'll see what I can substitute for colours. ahhh... another project found.
