My first thought is Bethel Bakery - awesome cakes! also know from wedding cake search that Patty Cake is very popular - there's also a place that used to be called Christopher's in Murrysville - believe it or not jI ust had a Sam's club cake that was great but icing very sweet - any grocery store has smash cakes - USA Gourmet in the Strip - Moio's is popular but Bethel is way better! Oh, almost forgot - Whole Foods in East Liberty has really yummy stuff - fancy too - and one of their "regular" cakes could be a smash cake - my youngest has allergies so we did a vegan cake for her 1st - cost about $14 and was surprisingly very good - especially the chocolate - and they do a phenomenal job w/ decorating! let us know what you find! have fun!
