When browsing for tea party planning ideas, I came across this cute product from Fred and Friends: Teacupcakes! This website has so many interesting and funny home products, perfect for parties, hostess gifts, or just to add some quirky style to your own home. How clever would these be for a tea party birthday cake option? They come in sets of four and are made out of 100%-pure silicone and phthalate-free plastic with matching saucers. Pour in the cupcake batter, bake, frost, and start singing, "Happy Birthday to You!"
