Can you purée fruit in pike lets or muffins and freeze them for snacks?

Fruit free snacks -
Nuts
pepitas
Pop corn
Cruskits, crackers, corn cakes (waaaay nicer than rice cakes! ) with PNB, jam, cheese and mashed avo, cream cheese and tinned salmon mixed together - yum!
Tinned tuna
Creamed corn on toast with melted cheese (is that healthy?!)
Homemade bikkies - heaps of healthy recipes out there (again, freeze them and they're ready to eat straight from frozen)
Crumpets - nice with melted cheese as well as the usual sweet toppings
Dry cereal
Chai Latte (with a tea bag so there's no sugar)
