There's no dessert like this vs. There's no such dessert as this

I was wondering if the following statements mean the same.

There’s no dessert like this.

There’s no such dessert as this.

It seems obvious to me that the second one could mean something like: There’s no such thing as this in the world of desserts or I’ve never seen it in the world of desserts.

The first one, however, sounds ambiguous to me because it could not only mean the same as the other, but also mean like: This is the best dessert I’ve ever enjoyed.

I know "like" implies comparison. Does the first sentence sound ambiguous to you too or does it only have one meaning?
