I like a little honey or maple syrup here and there. I add them to plain greek yogurt with a little something that gives a crunch (usually hemp seeds and cacao nibs). Otherwise if you're on the go, my favourite bars are Larabars. They are super clean (sweetened with dates) but pretty high in calories (about 200 something) so I would eat those sparingly.
I know you're not into fruit but I would also give dried fruit a go. They are full of fibre and naturally sweet. My favourites are apricots, figs, cranberries and mangoes.
Also, this is my favourite "clean deserts" recipe blog:
