Blessing, Texas is a neat, little town. My Mother and her siblings grew up around Blessing and Midfield (a couple of miles outside of Blessing). It doesn't get a lot of attention... I'm glad you stopped and enjoyed the fare. Enjoy.
I re-read the OP; sorry, I thought you had already visited. No, it's not too far to drive from Austin to Blessing (it may just seem like it...you're in Texas, remember?
) There are plenty of places to see along the way, and if you're already going to be in Blessing, you might as well drive a litte further and go see some of the coast, i.e., Palacios, Matagorta, etc.
