In a medium bowl or a large jar, combine oats, almond milk, chia seeds, vanilla protein powder, cinnamon, nutmeg, shredded carrots, chopped pecans, and raisins. Stir the mixture well until everything is evenly distributed and all ingredients are moistened. Cover the bowl or jar and refrigerate for at least 1 hour or overnight for the best flavor and creamy texture.

In a microwave-safe bowl, add the white chocolate chips and melt them in the microwave in 30-second intervals, stirring frequently until smooth. Once melted, mix in the Greek yogurt and cream cheese, blending thoroughly to create a silky ganache. Set aside to cool slightly while the oats soak in the fridge.

After the oat mixture has soaked overnight, pour the creamy ganache over the chilled oats, ensuring an even coat. Stir gently to combine the ganache with the oats, then cover the jar or bowl again. Place it back in the refrigerator and let it chill for a few more hours to meld the flavors together.

When ready to enjoy your Carrot Cake Overnight Oats, take them out of the refrigerator. Serve the oats in individual bowls, garnishing with additional shredded carrots, chopped pecans, or your favorite toppings like fresh fruit or a drizzle of maple syrup.
