I wanted to help by giving guidance on some non-gluten options you can ask your cake maker (baker or pastry chef). Of course there are tons of bakers out there that will use gluten free flour but in case they don’t, many bakers can make the following below.
1. Having a flourless chocolate cake
2. A pavlova or meringue cake
3. An almond flour cake
4. A cheesecake
5. Macaron cake fancy and fun (I recommend you contact https://m.facebook.com/derbycitymacarons/)
6. Ice cream
