Ingredients

  • Old fashioned oats
  • Vanilla whey protein powder
  • Fat-free milk
  • Egg yolks
  • Plain nonfat Greek yogurt
  • Cocoa powder
  • Granulated Swerve (or liquid stevia)
  • Salt
  • Mini chocolate chips

Substitutions & Swaps

Protein Powder

  • Vanilla whey protein works best.
  • Casein protein may create a thicker texture.
  • Plant-based protein can work, but the texture may be slightly denser. (I use Clean Simple Eats Simply Vanilla for this recipe.)

Milk Options

  • Any milk works (dairy or unsweetened almond milk).
  • Fairlife adds extra protein, but it’s not required.

Sweetener Options

  • Liquid stevia instead of Swerve.
  • Monk fruit sweetener.
  • Coconut sugar (macros will change).

Make It Even More Chocolatey

  • Add dark chocolate chips.
  • Stir in a spoonful of peanut butter.
  • Add a few raspberries before baking.

Why You’ll Love These Chocolate Baked Oats

  • ✅ High-protein breakfast
  • ✅ Perfect for meal prep
  • ✅ Chocolate flavor without tons of sugar
  • ✅ Portion-controlled
  • ✅ Kid-approved but macro-friendly
  • ✅ Reheats beautifully

These are especially great if you’re someone who struggles to get protein in at breakfast. The whey protein + Greek yogurt combo gives you structure, flavor, and staying power.

Recipe Tip

You can mix these up and store them uncooked in the fridge.

When ready to eat:

  • Microwave on high for about 1:30.
  • Microwaves vary, so add more time if needed.

This gives you a fresh-baked texture without turning on the oven.

Perfect for busy sports mornings.

How these Baked Oats Work

Instead of blending the oats completely into flour, you pulse them just slightly. This keeps some texture while still giving you that soft, cake-like center.

Each bowl is mixed individually, which makes portion control easy and keeps the macros accurate per serving.

The egg yolk adds richness, moisture, and structure — giving you that brownie-like texture without needing oil or butter.

Why I Use Clean Simple Eats Protein

I get asked all the time what protein powder I use in my baked oats, and the answer is almost always the same: Clean Simple Eats Whey Protein Isolate (Simply Vanilla).

Here’s why I love it for recipes like this:

  • ✔️ It bakes well without drying out
  • ✔️ No chalky texture
  • ✔️ Clean ingredients
  • ✔️ Easy on digestion
  • ✔️ Actually tastes good on its own

Not all protein powders behave the same when heated. Some get rubbery. Some get bitter. Some completely dry out baked goods. This one stays soft and gives these oats that cake-like texture.

Even if you don’t use my code, just make sure you’re using a whey isolate that bakes well — it truly makes a difference in the final texture.

Storing and Reheating

Store your Chocolate Bake Oats covered in the refrigerator for up to 5 days.

To reheat:

  • Microwave for 2–3 minutes until warm.
  • Add a splash of milk before reheating if desired for extra moisture.

They stay soft and fudgy even after refrigeration.

Freezer Option

You can freeze these baked oats.

  • Let cool completely.
  • Wrap tightly or store in airtight containers.
  • Freeze up to 2 months.
  • Thaw overnight in the fridge before reheating.

    1. Hi Lylah, I just really felt like this one needed the fat from the egg to make it good and have a good consistency.
