I think this recipe is amazing without added sugar but if you'd like it to be a little sweeter, you can add 2-3 tbsp of maple syrup or coconut sugar when you add the cinnamon and nutmeg. Without added sugar it's sweet but it can be a little bit tart depending on the type of apple you use. I've made it both ways and while extra sweetness is tasty, I don't think it's necessary and I like keeping the recipe sugar-free. Everyone that's made it sugar-free loves it too. Up to you!
