A couple of ideas to steal...guests were asked to dress in pink or blue to indicate their guess...a colored gumball hidden inside the cupcakes denoted the gender (everyone bit into their cupcakes at the same time).
I am always looking for a good excuse to throw a fabulous party, so when I came across this Gender Reveal Party, I fell in love! With my second child I did something similar, but on a smaller scale, for sure. Click here to see the full post.
How about edible cupcake toppers? If doing a simple shape such as this star, go ahead and top your cupcakes with decorated sugar cookies. So cute and tasty!
