I just made gluten free banana bread with nuts a couple of days ago. I used a regular recipe just replaced the wheat flour with an all purpose flour. I didn't have any xanthum gum so made it without. It didn't crumble too badly and next time I will use it. I bought more yesterday so I'd have it next time. the Xanthum gum helps to keep it from crumbling.

I make my Nestle toll house choc chip cookies with the GF all purpose flour and I can't tell the difference. My grands can't tell the diff either.

You do need to check your baking powder and baking soda for wheat. Not sure about the soda. it many not have any. I use it anyway as our GF is not a life threatening situation and a little bit won't hurt us. One of these days I will order the GF version online.

Some chocolate bars do not have any gluten in them. Hershey's milk chocolate bar with or without nuts is gf.
Toffee bars don't have any gluten. However I found out the hard way that tootsie rolls DO have gluten! I ate a tiny one my dgs had left and the next thing I knew I couldn't breathe.

I use homemade cocoa when I get to craving sweets and chocolate in particular. I also have to avoid corn and soy so I can't eat any chocolate candy anymore unless I make it at home.

Another idea if he likes them is no bake cookies. It is made with cocoa sugar peanut butter and butter and oats. No gluten there. But you do have to use gluten free oats.

Oats do not have gluten in them but the reg oats are processed on machinery which uses wheat flour to grease the machinery or has processed gluten products before processing the oats. So the reg can be tainted with wheat.
It is a bit more expensive but worth it.

Another idea would be to make homemade fudge or other homemade candy. I searched for gf candy ideas and there are a lot of them. if he has a favorite candy you might be able to find a gf version you can make at home.

Substituting is the key to eating the things you enjoy and not being so limited.
