I've been dying to try Mr. Cupcake in Clifton, NJ for a while and this past weekend, a cupcake craving hit hard. You can see my full review at Yelp.com
I think Mr. Cupcake does smart advertising. I got a coupon in the mail for two free cupcakes, no strings attached. It was enough to push my craving over the edge, and just so I didn't look cheap -I paid for two additional.
Overall I gave them four stars. I found their cupcakes to be slightly undercooked - but not necessarily in a bad way. Some people make them dense, others make them fluffy. I would say these definitely lean towards dense. I missed the cupcake wars show on 6/27 but plan to try and catch the re-run on DVR.
From Top Left - PB&J, Carrot Cake, Oreo Cheesecake, French Toast. 
However, I remembered I had bought this
So I baked a quick batch of funfetti cupcakes and decorated them with homemade sugar cookies. I may use box mix from time to time, but I always bake cookies from scratch. Funny enough I generally always have the ingredients to whip up cookies on hand as well, but I digress. I wanted to make them blue like Martha but I’m out of blue food coloring, so I settled with green. I secured a "Happy Birthday" cookie to a "Rachel" cookie with a bit of icing then stuck them in the cupcakes. They were a big hit and the surprise made my friend smile, all I could ask for.
