The Wales international striker was due to be on loan at Swansea until the end of January, but a bid from Palace was accepted by MK Dons and the 29-year-old joined on a two-and-a-half-year contract.
Dougie Freedman's side lie one place and four points above the relegation places after Saturday's win over Middlesbrough, and Easter is relishing the opportunity provided by his long-term deal.
"I have not been there long but I am enjoying being back in the Championship," he said.
"My spell at Swansea went well but Palace made an offer before the loan was up and MK Dons accepted it.
"It's a reasonably long-term deal. I have just relocated and my wife is moving down with me in a few weeks. I feel I am settling in well."
