easy dessert recipes with basic ingredients

Can someone please recommend some recipes for me for desserts, particularly chocolate?

Please note that I can not use nuts as I am allergic and since I live alone I do not have access to a lot of ingredients.
I don't mind buying the ingredient if it can be used often in other things, etc. I don't really want to have a cabinet full of baking ingredients.

Ingredients I have so far : vanilla whey protein powder, flax seeds, chia seeds, chocolate chips, maple syrup, soy milk, greek yogurt, berry granola, frozen berries, whole wheat cereal


Thanks in advance:)
