Homemade Bars > Store-Bought!

Last year, my husband’s trainer told him he needed more protein. He’s never been a fan of protein or granola bars, but he wanted something quick he could snack on or take with him. So, I was determined to make a homemade protein bar he’d actually enjoy—and as a bonus, skip all those store-bought bars with ingredients I can’t even pronounce.

I’ve always loved bars like Perfect Bars, G2G Bars, and Go Macro Bars for their flavor, texture, and more reasonable ingredients, so that’s the kind of vibe I was going for when I started testing. After a few tries, I landed on the most delicious bar—and now I can’t stop making them. I have to double every batch because they disappear so fast.

And the best part? They’re saving my grocery budget too. Homemade wins all around!

It doesn’t get much easier than that!

Is Making Your Own Protein Bars Cheaper?

Yes, making your own protein bars is almost always cheaper in the long run. The ingredients might cost a bit more upfront, but you can make a big batch—so each bar ends up costing way less.

Store-bought bars usually run between $1.50 to $3.00 each, while homemade ones can be much more budget-friendly depending on what you use.

Plus, you get to control exactly what goes in them—no mystery ingredients—and you can tweak the recipe to match your flavor and texture preferences perfectly!

Ingredients In Homemade Protein Bars

  • Old-fashioned oats: Give the bars shape and a chewy texture.
  • Peanut butter: Smooth works best. You can also use cashew or almond butter.
  • Honey: Sweetens and holds everything together. Add more or less to taste.
  • Vanilla extract: Adds flavor but is optional.
  • Salt: Makes everything taste better. Skip if using salted peanut butter.
  • Vanilla protein powder: If your protein powder is already sweet, use less honey. You can add more later if needed.
  • Mini chocolate chips: Use dark chocolate for less sweetness.
  • Optional chocolate drizzle: Skip for a simpler bar.

    DANGER-these are so good that itโ€™s easy to gobble 600 calories in an instant ๐Ÿ˜‚. Seriously though I made these with almond butter which I far prefer over peanut butter, omitted coconut (for once in my life) and used Orgain vanilla protein powder. Just SO GOOD. I also made some with chocolate powder and theyโ€™re almost as good. YUM YUM!

    Can the bars be used when on KETO

    1. Chelsea Lords says:

      I’m so sorry I’m not familiar enough with the KETO diet to give recommendations; I’d work with a nutritionist on that!

    thank you for this recipe, I eat commercial protein bars all the time, but very few measure up for long, just get sick of them and most are loaded with sugar, so really nice to be able to make my own with your recipe
