Hello any recommendation for baby shower cake set for guest? Prefer less sweet cake choices. TIA

How about a Matcha flavoured cake? I feel that matcha cakes are always a nice mix sweet, fragrance a hint of bitterness that's oh-so exquisite. You can order a ready made cake from Patisserie Glace. If you are looking for something more customised, "A Little Cake Shoppe" has a selection of cakes with sugar content that's not too high. http://alittlecakeshoppe.com/

Not a typical bake shop that caters to baby shower or events. But my friend got some cakes from them earlier this year and requested for lower sugar content and was very pleased with the cakes. You could consider getting their cupcakes if not having a cake set is an option you don't mind considering. Little Favors By Ethel https://littlefavorsbyethel.com/cupcakes/
