Right out of Kitchen, Kill hallway monster, clear TV room, enter crawlspace, grab spice.
Down the ladder, clear the drained passage, grab the chicken at the end.
Crowbar the first Blob in the prison area, then grab the Blue Blaster and shoot everything between you and the stairs back up. Your Blaster should last long enough to shoot everything in the storage area after the couch room. Pick up the sugar and spice there. If the Green key Molded doesn't appear immediately, don't wait for it.
Up the stairs, clear the hall, kill the Red Key Scyther in the Library.
Kill the molded outside the closet-under-the-stairs again, then run upstairs and kill the molded in the cassette room.
Run to the largest attic room, crowbar the four Molded, then the bobblehead, then the Blue Key Molded. It's arachnid, but there's not really enough space here for it to dodge away from you.
You should have 2-3 bonus minutes on the clock now. Plenty of breathing space. Grab the Stew here, then go the Far Attic room and pick up the Cake. Sugar the Cake and Spice the Chicken and the Stew.
Grab the Cake from the Bathroom and the Chicken from the TV room.
Feed Everything to Jack.
Notes: This run could probably be made even faster by using the Cheese in the hall closet with the Bathroom cake.
