Ingredients
1/2 cup rolled oats
3/4 cup milk of choice (dairy or unsweetened almond/soy)
1/2 cup plain Greek yogurt (0-2% or full-fat)
1 scoop protein powder (about 25-30g; vanilla or unflavored work best)

Notes
Cooking Tips
-
Prevent protein clumps: Always whisk protein powder into the liquids before adding oats.
-
Texture control:
-
Thicker: add chia seeds or reduce milk slightly.
-
Thinner: add 2–4 tbsp extra milk in the morning.
-
-
Best oats: Rolled oats give the best creamy-but-chewy texture. Quick oats get softer; steel-cut need more liquid and longer soaking.
-
Sweeten after chilling: Some protein powders are sweet—taste in the morning and adjust.
-
Meal prep friendly: Make 3–5 jars at once; they keep well up to 4 days.
Variations
-
Peanut Butter Banana: Add 1 tbsp peanut butter + 1/2 banana mashed (reduce sweetener).
-
Chocolate PB: Use chocolate protein powder + 1 tbsp cocoa powder + 1 tbsp peanut butter.
-
Berry Cheesecake: Stir in 1/4 cup mashed berries and top with extra berries + crushed graham crackers.
-
Apple Cinnamon: Add 1/2 cup grated apple, 1/2 tsp cinnamon, and a pinch of nutmeg.
-
Mocha Oats: Add 1–2 tsp instant espresso + vanilla or chocolate protein powder.
-
Dairy-Free: Use soy milk + dairy-free yogurt; choose a vegan protein powder.
