Can one make Rice Krispie marshmallow squares without vanilla extract?

It’s just a flavoring, not essential to the recipe.

I’ve never heard of adding vanilla and can’t find a recipe that calls for it. Sounds kinda gross – too sweet.

In every recipe I’ve seen, vanilla extract seems good only for the smell/aroma factor. So little is used it couldn’t possibly add anything at all to the overall flavor.

I never put vanilla extract in Rice Krispie treats.

I have always used vanilla extract as it adds flavor.
