I recently flew to Chicago for my cousin Angie's baby shower. I grew up with Angie, and we've been best friends for as long as I can remember. Her friends in Chicago were organizing her baby shower, but I wanted to contribute something, so I offered to make some onesie cookies!
I used my usual sugar cookie recipe from Peggy Porschen's book "Pretty Party Cakes", and used the same onesie cookie cutters (from my previous attempt at baby shower cookies) to cut out the shapes. Once those were baked and cooled, I outlined the cookies with white royal icing (recipe also from "Pretty Party Cakes"). After the outlines had dried, I filled them in with thinned royal icing, and then let that dry overnight.
I wanted to make the cookies match the baby shower invitations, so I used orange royal icing to outline half of the cookies, and blue/grey royal icing to outline the rest. It took me a while to match the blue color to the one in the invitations, but I ended up mixing in royal blue, black, and a teeny bit of purple to achieve the right shade.
Angie's friends did an awesome job with the baby shower - everything was beautiful, and the food (Korean food made by Angie's cousin-in-law) was deelish! I was so happy that I was able to make the trip to participate in the celebration!
