In his first game of 2014, Colin Ryan led the charge for the hosts, scoring 1-13, including a 12th-minute goal from a penalty after a foul on David Reidy.
Clare faced a UCC side playing their second game of the weekend; the students lost to Cork Senior hurlers in the annual Canon O'Brien fixture on Saturday afternoon.
Along with Ryan, Davy Fitzgerald welcomed back Patrick Kelly, David McInerney, Cian Dillon, Patrick Donnellan, Brendan Bugler and Conor McGrath, from the 2013 All-Ireland winning side.
Clare led throughout this game and were up 1-06 to no score after 12 minutes, following Ryan's goal. Conor McGrath and Pat Donnellan were also among their early scorers.
UCC responded before the break with a goal from Cork's Pat Deasy but Ryan brought his tally to 1-05 by the interval, as Clare held a 1-10 to 1-03 interval lead.
However, Clare were in flying form on the restart, holding their opponents to just a point in the closing 35 minutes.
David O'Halloran sealed the issue with Clare's second goal in the 68th minute, as the Banner County recorded a 27-point win.
Meanwhile, the other semi-final between Tipperary and UL fell victim to bad weather; the games was postponed due to an unplayable pitch at MacDonagh Park in Nenagh.
The Munster Council have yet to announce a date for the re-fixture.
