Ingredients and substitutions

Rolled oats. I recommend rolled oats over quick oats because it's more forgiving with liquid and has a better texture in my opinion.
Yogurt and Chia Seeds. The use of these helps with the overall texture of the overnight oats. I'd definitely recommend the chia seeds, but you could omit the yogurt.
Grated carrot. No need to squeeze out the excess moisture, I've accounted for this in the final ingredients.
Spices. I've recommended cinnamon and nutmeg. You can adjust as necessary or include additional like ginger and allspice for something really flavourful.

Top Tip
Grate the carrots finely. This helps them blend seamlessly into the oats, keeping the texture smooth while still adding that classic carrot cake flavor.
Adjust sweetness to taste. Depending on your protein powder and personal preference, you can add honey, maple syrup, or a mashed banana for natural sweetness.
Top just before serving. Add nuts, extra cinnamon, or a drizzle of nut butter right before eating to keep them fresh and crunchy.
Recommended equipment
To grate the carrots finely, I use the thin shredder attachment on a Food Processor. This helps them be smooth in the overnight oats without being overpowering. Of course, you could use a simple grater.
I also love the use of Overnight Oats Jars as they have a lid that seals well and there's even a little attachment for a spoon.
Meal prepping overnight oats

Meal prepping carrot cake overnight oats is an easy way to have a nutritious, high-protein breakfast ready to go for busy mornings. The combination of oats, chia seeds, and yogurt ensures a thick, creamy texture that gets better as it sits overnight, or up to 4 days in an airtight container.
It can thicken each day, so stir in a splash of milk if they get too dense.
Can you reheat overnight oats?
Overnight oats are typically meant to be eaten cold but you can make them similar to stove-top oats by adding in a splash of liquid and microwaving on 30 second intervals until warmed through (should take about 2 minutes).

FAQs
No, finely grated raw carrots soften overnight as they absorb moisture from the oats and milk, blending seamlessly into the mixture.
Absolutely! Raisins, chopped dates, or shredded coconut all work well to enhance the carrot cake flavour.
Steel-cut oats don’t soften as well overnight and will remain chewy. If using them, soak for at least 12 hours or cook them slightly first.
