Simple Baked Protein Bars

Are you ready to make your own healthy protein bars at home?! These Simple Baked Protein Bars are inexpensive, only take a few ingredients to make, and come with endless variations! If you’re looking for a delicious and quick protein bar recipe, this is the one to try.

You’ll need a baking dish (8×8 preferred), something to mix your ingredients in like a shaker bottle, and an oven to make this.

Add right into whatever you’re using to mix your ingredients in 4 large egg whites, 1/2 cup of unsweetened apple sauce, 2 scoops of your choice flavor protein powder, 2 packets of your choice sweetener, 1/4 teaspoon of vanilla extract, 1 tablespoon of peanut butter, and 1/4 cup of rolled oats.

Choose a flavor protein powder that compliments your peanut butter!

Mix all of those ingredients together until everything for your simple baked protein bars is incorporated.

Take out your baking dish, coat it with some non-stick cooking spray, and pour your mix in. Make sure to evenly distribute your mix across your dish if it’s thick.

You can easily change up the size and shape of your protein bars by using various size dishes. Keep in mind here that your baking time may also change depending on the size dish you’re using. Thicker bars? Add more time! Thinner? Subtract some time!

Top your bars with anything else you want before the oven and bake them on 350F/176C for around 20 minutes. Once the edge pull away from the sides your simple baked protein bars are done.

Remove them from the oven and optionally top them. I topped mine with some light whipped cream and ground cinnamon today.

Protein Bar Tips

  • Top it with Greek yogurt, protein frosting, a nut butter, etc
  • Make sure to use ingredients (protein) that tastes good
  • Mix and match all of your flavors to have endless variations
  • Blend the oats/use oat flour if you want a smoother bar

    I look forward to trying this recipe. I’ve been searching for a lower calorie protein bar that has at least 15 grams of protein. Thanks for this recipe!

      Hope you like them Christina!

        I’m currently making this recipe for the third or fourth time. It’s yummy!

  2. Cha on May 18, 2017 at 12:00 am

    Do these freeze well?

    Thanks so much for posting these recipes!

    • Derek Howes on May 18, 2017 at 12:00 am

      Hey Cha! Sure, you can definitely freeze them. I would just make sure they are sealed well.

    Can you sub in pumpkin for the applesauce? I’m not allowed to have fruit on contest prep but I really want to make these!

    • Derek Howes on August 19, 2014 at 12:00 am

      I’ve never done that with this recipe but it’s worth a shot! Let me know if you do!

  4. Kandis on June 22, 2014 at 12:00 am

    So quick and easy to make! Made these last night….it was a bit of a dhftns weekend! Just need a smaller dish to cook them in because they were super thin (which isn’t a bad thing at all).

    Still bloody delicious!

    • Derek Howes on June 23, 2014 at 12:00 am

      Glad you liked them Kandis! Thanks my friend

    Hey Derek:

    I work out about 5-6 days a week and love all the high protein recipes you are doing here. Only suggestion…I’m diabetic so it would help for you to mention a lower carb version, or when carbs are slow digesting (like the oats in this recipe). Just sayin’.

    Keep up the great work!

    • Derek Howes on April 29, 2014 at 12:00 am

      Thanks for the awesome suggestion Russ! I’ll definitely do some lower carb stuff in the future.

  6. Sheldon on April 12, 2013 at 12:00 am

    Am I able to leave out the apple sauce on this?

    • Derek Howes on April 12, 2013 at 12:00 am

      No, they’ll end up really, REALLY dry!

      I love you recipe and its flexibility! I have followed it straight and subbed in pumpkin for applesauce in a pinch. It worked great!
      Thank you

  7. Jen on January 24, 2013 at 12:00 am

    My brother has a really late class this week, so I made some of these for the both of us, just to try it out. They were delicious! I am definitely making these more often! 🙂 Thank you!
    I am also planning on making your sweet potato pie, as I love sweet potatoes!

    • Derek Howes on January 24, 2013 at 12:00 am

      Glad to hear you guys liked them! The sweet potato pie is amazing! 🙂

  8. Toni on January 23, 2013 at 12:00 am

    Thank you for posting your recipes. I love the quick protein bars! (and how easy they are to make) I plan to keep these on hand.

    • Derek Howes on January 24, 2013 at 12:00 am

      No problem Toni! Thank you for the support
