In a first half where Dublin managed just one score - albeit a goal - it was always likely an improved second 30 minutes would be required to seal the three in a row.
Mick Bohan's side have swept all before them for three years, but were subdued for large portions of a contest where 2-03 was enough to finish with a relatively comfortable margin over a dogged Galway outfit.
It took 22 minutes to register Sinead Goldrick's goal and that was the only flag raised at the Hill end in the opening half.
Solid if not spectacular, the Dubs wore their opponents down with the game effectively won in the 10 minutes after the break with Lyndsey Davey and Hannah O'Neill claiming a point and a goal either side of a Galway yellow card.
Davey admits that the half-time team talk allowed Dublin figure out how best to overcome their pragmatic opponents.
"The conditions were a lot tougher than probably what they looked," the Skerries Harps player told RTÉ Sport.
"It was very slippy. A few times I was going to turn and my feet were just going from under me, a few balls slid away."
"I think the way Galway set up, they were so clustered in defence, I think we probably played right into their hands. We tried to drive through the centre of them and we were getting turned over.
"I think in the second half we kind of settled a bit and played more to our strengths."
The game was played in front of a record attendance of 56,114 and the 31-year-old says it marks a seismic change from the start of her Dublin career in 2004.
"I know when I was younger and you come into Croke Park and watching the men playing in a full stadium, you think to yourself, 'I'd love that to be us one day'. Then you're not sure if you will be playing by the time that happens.
"Fifteen years later, I'm still here. It was a very special moment for us."
The four-time All Star was arguably the key figure after the break, chipping in with 1-01, and says while she has considered for a number of years hanging up the boots, victory makes it all worthwhile.
"Sport is very unpredictable. To give it another year is a massive commitment. There were no guarantees we were going to get back here and the chance to go for three in a row.
"I've been saying one more year for a lot of years now."
The decision by Bohan to take over three years ago was just the motivation she required to focus on the next chapter of her inter-county career.
"Who would have thought three years later we'd be sitting here after winning a third successive All-Ireland?"
