Responding to a question about what they like to cook together after they were filmed in a kitchen for a YouTube Short, Travis said: "That's a good question.
"I respect that question, but I'm going to keep that one to myself because I thoroughly enjoy cooking with her, so it's something I'd rather just keep personal."
However, he did spill the sweet treats the 'All Too Well' hitmaker makes well. Travis added: "Taylor makes a great Pop-Tart and cinnamon roll."
Dating one of the biggest stars on the planet means Travis is often asked lots of personal questions, and he was recently grilled about plans to propose to Taylor during an awkward moment at a charity event.
The football star was at the Big Slick Celebrity Weekend in Kansas City, Missouri - which raises money for the Children's Mercy Hospital - alongside his Kansas City Chiefs teammate Patrick Mahomes and actor Paul Rudd and he appeared in a skit with actor/comedian Jason Sudeikis who pinned the sportsman down on whether he is going to tie the knot with his girlfriend.
Sudeikis asked him: "Hey Travis, real talk OK, just the guys here. Hey, when are you going to make an honest woman out of her? Taylor doesn't need to be working anymore."
Travis smiled, rubbed his beard, and pointedly refused to answer the question.
It comes after New York Post column Page Six reported Travis plans to pop the question this summer on their first anniversary in July.
An insider told the publication: "They don't want it to seem like it's rushed insanity ... Taylor and Travis discussed it and there is a plan ... They will get engaged on their one-year anniversary in July."
The couple are believed to have got together in July 2023 and Taylor went on to make her first public appearance supporting Travis at one of his football games in September.
Taylor previously admitted the pair enjoyed plenty of time together at the start of their romance before going public.
She revealed they started hanging out after the sportsman mentioned her on his 'New Heights' podcast.
She told Time magazine: "We started hanging out right after that. So we actually had a significant amount of time that no one knew, which I'm grateful for, because we got to get to know each other."
