One way of thinking about it . . . what do you mean by 'from now'? Why would it even be necessary? FROM NOW generally means, starting now, and is more commonly used as FROM NOW ON. e.g. "I don't want to be tired all the time. From now on, I'm going to bed on time."
I suppose FROM NOW can also man 'as opposed to from some other time period', but that doesn't seem relevant to your sentence.
So, I don't think it's so much of a grammar problem as a problem of it not making sense. If you make pancakes, we can assume you are making them at the time you are talking about. FROM is the most problematic part. Are you going to be making pancakes from now until some future time?
You could just say NOW, but even that feels unecessary.
