Once the carrot pieces look noticeably softer, reduce heat to medium. Now comes the fun part—the addition phase. Stir in your rolled oats, raisins, cinnamon, allspice, vanilla extract, walnuts, and crushed pineapple (juice and all). This is when your kitchen will smell absolutely incredible. Let your kids smell the spices before they go in. Talk about what they notice. The mixture should bubble gently and look thick. Make sure kids stir with a wooden spoon and aren't leaning directly over steam. Simmer for three to four minutes, stirring frequently. Watch for the moment when the liquid begins to get absorbed and the mixture starts looking creamy.
