I recently received a free sample pack (containing 2 tarts) of Pop Tarts' newest flavor:  Blueberry Muffin.
I was really excited about them, couldn't wait to try them...and I was so disappointed.  The filling is basically watered-down icing with blue sprinkles in it, and the entire thing was so sickeningly sweet that I couldn't even eat the second tart.

Overall, just not a commendable effort by Pop Tart.
