Add all ingredients (except sprinkles) to a jar or bowl and stir to combine (make sure there are no chia seed clumps!). Cover the container and place in the fridge overnight, or at least 4 hours.
1/3 cup milk, 1/4 cup Greek yogurt, 1/4 cup old-fashioned oats, 1 tablespoon chia seeds, 1 tablespoon ground flax seeds, 1 scoop cake batter protein powder
Before serving, give the oats a stir. The oats will absorb much of the liquid, and different protein powders can affect absorption, too, so add an extra splash of milk if needed.
Once oats are at your preferred consistency, stir in the sprinkles then serve and enjoy.
1 tablespoon sprinkles
Notes
To make with vanilla protein powder but still get a cake batter flavor, add 1/4 teaspoon each of vanilla extract and almond extract. You can also add a teeny 1/8 tsp of butter extract if you have it, too!Nutrition information is an approximation and will vary based on exact ingredients used.
