01 - Combine oats, almond milk, Greek yogurt, maple syrup, cinnamon, nutmeg, ginger, vanilla extract, and salt in a medium mixing bowl or large jar. Mix thoroughly until all ingredients are well incorporated.
02 - Gently fold in grated carrots, raisins, and chopped nuts. Distribute evenly throughout the mixture.
03 - Stir everything together completely, ensuring the spices and sweetener are evenly distributed and no dry pockets of oats remain.
04 - Cover the container and refrigerate overnight, or for a minimum of 8 hours, allowing the oats to soften and flavors to meld together.
05 - In the morning, stir the oats well. Add a splash more milk if the consistency is too thick. Serve chilled, topped with additional nuts, a sprinkle of cinnamon, or a dollop of yogurt if desired.
