The champions, featuring 13 of last year’s successful side, looked to be in for a challenging afternoon as an early 0-4 to 0-1 was wiped out when DCU had points from Carol Hegarty, Sarah Rowe and Lorraine O’Shea.
A penalty from Roisín Leonard put UL back in front in the 16th minute, however, and they led from there, with 1-9 to 0-6 the half-time score.
Driven on by Jennifer Grant and Lorraine Scanlon at midfield, they continued to build the lead in the second half, with two goals in six minutes from Áine Tighe leaving them 3-10 to 0-7 ahead.
From there, it was a procession as Leonard, sub Claire O’Sullivan, player of the game Niamh O’Dea and Aileen Wall all featured on the scoreboard, with DCU limited to two Rowe points in the final quarter.
Earlier, Trinity College beat Athlone IT by 1-16 to 1-9 in the second-tier Giles Cup while there was some consolation for DCU as they overcame DIT on a 2-13 to 1-10 scoreline in the Lynch Cup. St Patrick’s College were the Donaghy Cup champions, beating Liverpool Hope University by 5-10 to 0-1.
