Why You’ll Love This Recipe

This decadent tasting breakfast is super simple and surprisingly healthy. With 21 grams protein per serving, you can have your cake for breakfast and eat it too!

These overnight oats are exceedingly simple, as long as you have some birthday cake/cake batter/cupcake/funfetti flavored whey protein hanging around. And sprinkles, of course. Don’t forget the sprinkles. Once you’ve got those things, it’s a [birthday] party. I topped my oats with some whipped cream, which lends even more birthday cake vibes to this breakfast. You could also top it with some Greek yogurt and fruit like blueberries or bananas. Enjoy!

How Far in Advance Can I Make Overnight Oats?

The name would suggest that you need to make them the night before you eat them, but I’ve made them up to 6 days in advance and haven’t had any issues. For most overnight oats recipes, the texture starts to change slightly after about 3 days in the refrigerator. People worry a lot about oats getting mushy if they don’t eat them within a day or two, but I find they get more creamy than anything. You may also find that some of the liquid separates or that they seem to dry out – just give them a stir and add more of your milk of choice to revive them!

If you’re worried about whether you’ll still like them after a few days, I’d recommend 2 things: 1) make a test batch and give it a try on day 4 and 5 to see if you like it. Don’t put all of your proverbial eggs in that breakfast basket on those days – have a backup ready to avoid any frustration or disappointment if you don’t like them. And 2) if you find you don’t like their texture on days 4, 5, 6, etc. – mix up the dry ingredients in a jar ahead of time and stash it on your counter. Then all you’ll have to do is add the wet ingredients and stick it in the fridge overnight when you’re ready for it!

Another pro tip: always be sure to use the regular or thick rolled oats/old fashioned oats. There are quick cooking rolled oats out there that will lose their chew way faster than the thicker ones. Bob’s Red Mill actually makes these Extra Thick Rolled Oats that are perfect for overnight oats!

Ingredients and Substitutions

Here are the ingredients you need to recreate these Birthday Cake Protein Overnight Oats:

  • Rolled oats – I prefer to use rolled oats (also called old fashioned oats) in my overnight oats recipes because they maintain some chew even after a few nights in the fridge. Quick cooking oats turn to mush and steel cut oats have too much bite (even if you use the quick cooking kind).
  • Protein powder – A cake batter flavored protein is critical to nailing the birthday cake flavor. I used this brand because it was readily available to me at Target, but there are others on the market that would also be delicious!
  • Greek yogurt – Danon Light and Fit FF Vanilla Greek yogurt has been my go-to for years. It helps make these oats extra creamy while adding a boost of protein. If you want to use a dairy free yogurt, check out my recommendations here.
  • Milk – Use whatever neutral tasting milk you prefer! I used almond milk, which doesn’t have a strong flavor. Some non-dairy milks have a really strong flavor or are overly sweet – I’d stay away from those in this recipe.
  • Chia seeds – If you’re not familiar with them, they’re the little black specks you can see in the overnight oats. As they sit in liquid, they soak up moisture and help your overnight oats thicken up and get really creamy. Plus they’re a great source of fiber and antioxidants!
  • Sprinkles – Use sprinkles that actually taste good! I like the rainbow chip style ones for this recipe, but be sure to add them just before serving or they will dissolve before you get to enjoy them.
  • Vanilla – Like salt in a savory dish, vanilla tends to enhance the flavors of a sweet recipe.
