01 - In a medium bowl or jar, combine oats, milk, Greek yogurt, grated carrots, maple syrup, and vanilla extract. Mix thoroughly until all ingredients are well incorporated.
02 - Sprinkle in cinnamon, nutmeg, ginger, and salt. Stir continuously to ensure spices are evenly distributed throughout the mixture.
03 - Gently fold in chopped nuts, raisins, and chia seeds if using. Ensure the add-ins are evenly dispersed.
04 - Cover the bowl or jar tightly and refrigerate overnight, or for a minimum of 6 hours, to allow oats to soften and flavors to meld.
05 - In the morning, give the oats a thorough stir. If the mixture appears too thick, add additional milk 1 tablespoon at a time until desired consistency is reached.
06 - Divide the mixture evenly between two bowls or jars. Top with additional nuts, shredded coconut, a dollop of Greek yogurt, or a drizzle of maple syrup as desired. Serve chilled.
