Quite possibly the EASIEST breakfast you can ever make, aside from maybe cereal.

I don’t know how I’ve slept on overnight oats for so long, but they’re about to become a staple for me. In case you’re new to the oats game- overnight oats are basically just mixing all the goodness together to make oatmeal, but instead of heating it up, you let it sit in the fridge overnight. In the morning you’re left with thick, delicious oatmeal that requires zero cooking.

It’s basically the cold brew of oatmeal, and I’m officially into it.

Want to enjoy some cake batter for breakfast? While also getting in a decent amount of protein? Heck yeah, ya do. Let’s do it…

  1. Combine everything in a bowl and mix well. Start with 1/2 cup of milk and add more if you’d like. I used 3/4 cup milk and it still came out very thick (swipe for the thickness) but some like it thicker.

  2. Add to fridge in a bowl or mason jar and let sit overnight, or for at least 2 hours. Remove from fridge, top with some whipped cream and additional sprinkles and enjoy!


  • The butter extract is optional, but helps create a cake batter flavor.
  • You can also omit the powdered sugar or swap it out for a different sweetener, but I find the powdered sugar to work best for the flavor we want here!
  • Any type or flavor of protein will work here. Since this requires no baking, just go with a protein powder that you enjoy the taste of.
