Yeah, stevia actually has a taste that lasts longer than sugar, even though it has a onset that is slower. Would you try it ?
You can get stevia drops that are a liquid for and very concentrated.  The only problem is some brands can have a bitter taste so you have to be careful not to ruin your cake.

Well, I know that stevia is a sweetener that serves as a sugar substitute, it is extracted from Stevia rebaudiana's leaves okay, i am aware of it but it only comes in packets i think and not in bulk for baking
Stevia's taste has a slower onset and longer duration than that of sugar, and some of its extracts may have a bitter or licorice-like aftertaste at high concentrations.
