I may be too late for your cooking...
I never put sugar in oat topped crumble. Here's a sugar free recipe
1.5 cups oats
0.5 cup flour (plain flur or rice flour or ground almonds if nuts are safe)
big spoon butter
cinnamon
optional peanut butter (again if nuts are safe otherwise leave out)
Whizz the oats, add flour and cinnamon, mix, add butter mix, add peanut butter if using, mix.
So that is a recipe I picked up somewhere on the internet and I may have followed it once, but I generally don't follow recipes, I measure out nothing and just throw things in. I don't usually add flour so it's fine without, I tend to add vanilla and cinnamon. You can also sweeten it up (if needed) with things like whizzed prune or raisins.
Some sugar free fruit mini muffins would go down well, or the fruit pancakes you mentioned, banana bread, banana blondies, flap jack (oaty chews), bread and butter pudding served cold in slices.
Just lots of lovely fruit on a platter would be great, or how about some festive fun and serve up Santa Strawberries? Kids love them!

I also just use a knife to form the beard and don't bother with a piping bag, much less hassle. You need to make eyes out of something, a tiny cube of sultana would do it. Pack them standing upright into a container to transport them so they don't fall over.
