Protein Overnight Oats Base Recipe

Recipe by Danielle

Make this 4-Ingredient Protein Overnight Oats Base Recipe with any flavor protein powder! With over 30g of protein, this meal prep breakfast is delicious, easy to make, and even easier to customize with your favorite flavors!


  • Total Time4 hours 5 minutes
  • Yield1 serving 1x

Ingredients

Scale

For each serving:

  • 1/2 cup rolled oats
  • 3/4 cup unsweetened almond milk (or milk of choice)
  • 1 scoop flavored protein powder (any brand/flavor should work) (I use Just Ingredients Vanilla Bean)
  • 1 tablespoon chia seeds
  • optional: 1/2 cup fruit or berry add-ins


Instructions

  1. Mix up oats: Add the rolled oats (1/2 cup), unsweetened almond milk (3/4 cup), protein powder (1 scoop), and chia seeds (1 tablespoon) to a wide mouth mason jar or other container with lid. Stir vigorously with a spoon, being sure to mix in any dry spots at the bottom. Add your optional fruit or berry add-ins (max 1/2 cup) to the top (or add them when you eat). Repeat as necessary for each serving you’re making.
  2. Refrigerate: Put a lid on the jar and place it in the fridge for at least 4 hours, but preferably overnight. It will thicken as it chills.
  3. Serve: To serve, open the lid and stir once more to mix. Add any extras on top (berries, nuts, granola, etc). Enjoy within 4 days.

Notes

Add even more protein:
✔️ swap almond milk for dairy milk (+5g!)
✔️ add in 2 TB of Greek yogurt (+3g!)
✔️ add in 2 TB of peanut butter powder (+6g!)
✔️ add in 2 TB of cottage cheese (+3g!)

Sweetener: This recipe assumes your protein powder is sweetened in some way. If unsweetened, add 1 tablespoon maple syrup to each serving.

Protein powder options: As of March 2025, I’ve tried this recipe with 4 different flavors of protein and 2 different brands of protein. All tasted delicious! Feel free use your favorite kind and try any flavor of protein with this base recipe.
