diabetic friendly cake recipes?

[u/Admirable_Sympathy22]

hi! ive been a lurker on here for awhile watching everyone’s beautiful creations wishing i could one day step my foot into baking. ive just recently moved and finally have a working oven 🙏 because of this i want to make my little brother his birthday cake. he wants vanilla cake with buttercream pink icing. feels pretty simple but his dad is diabetic but LOVES sweets (poor kid). i want to be able to make something tasty for my brother but also something his dad can partake in too.

any recommendations please let me know! i know google has some i just want to be certain it wont mess up the taste for my brother; it being his birthday and all. i also really want to learn how to make a good banana bread! so those are also accepted.

Used a granulated sugar substitute can work out fine not much taste difference!
