Cereal Milk Overnight Oats

Cereal Milk Overnight Oats are made with cereal milk and packed with protein from Greek yogurt. Add a scoop of protein powder or chia seeds to keep you full even longer!

Overnight oats are a quick and easy way to meal-prep breakfasts for your family’s busy weekday mornings. Soaking the oats in milk and yogurt gives you a quick, no-bake breakfast that can be refrigerated up to five days in advance. There are endless variations on overnight oats, but today we have a unique “cereal milk” recipe that both kids and adults will love!

Jars of cereal milk

The overnight oats ratio we suggest is 1:1 oats-to-milk, with half the amount of yogurt. For cereal milk, we suggest 1:2 cereal to milk (1 cup of cereal soaked in 2 cups of milk, etc.). While customizing this recipe can be fun, don’t let the options overwhelm you! Some basic cereals that we suggest are:

  • A fruity cereal
  • A chocolate or cinnamon cereal
  • A classic cereal such as multigrain O’s or frosted wheat squares
  • You can also adjust this recipe to use chocolate milk, strawberry milk, or any dairy you choose!

You can also replace Greek yogurt in overnight oats recipes with cottage cheese for a delicious variation! Scoop cottage cheese straight from the container or blend into a whipped and creamy consistency for delicious cottage cheese overnight oats.
