Andrew Conway crashed over to make sure of a bonus-point win for the Irishmen, while a Kristian Dacey score and an early Simon Humberstone penalty was all Davies' men had to show for their efforts.
It condemned the Blues to their fifth RaboDirect PRO12 loss of the season and Davies believes Munster were too good a side to not take advantage of their mental errors.
"We were well beaten," said Davies. "The second half we did show some resilience out on the pitch, that was reflected in the final score line.
"You couldn't fault the effort, but we made too many fundamental errors throughout the course of the middle and end of the first half.
"With a team like Munster you can't gift them opportunities and that was the tale of it.
"We started well but gifted them too many chances. We went in at half-time and talked about what we needed to do. We delivered that and got some credibility back.
"We have players away and missing, but we expect better of ourselves.
"This group has been working hard the last few weeks and we have had three games. We have won two against a strong Treviso team and the boys played with a lot of passion last week at the Liberty.
"We knew this would be a step up for us, we felt we had identified areas in the game where we could capitalise and put pressure on them.
"We did that for 15 minutes at the start of the game and for certain periods in the second half. But we gifted them opportunities and they are too good a team not to take them."
