Making your own protein bars is not only economical—store-bought protein bars can be pricey—but you’ll also know exactly what’s in them.

Homemade Protein Bars stacked on top of each other.

Homemade Protein Bars

Last year, my husband’s trainer told him to eat more protein, but store-bought bars were expensive and had weird ingredients. So, I made my own!

These homemade bars cost less, have simple ingredients, and taste amazing. I don’t even need extra protein, but I can’t stop eating them!

They’re soft, thick, and chewy—like a “Perfect Bar.” The flavor is close to a peanut butter “Perfect Bar,” with a little protein powder taste, similar to a “G2G Bar” or “Go-Macro Bar.”

All the ingredients in this recipe prepped out for easy assembly.

How To Make Homemade Protein Bars

  1. Prep the Pan: Line a bread pan with parchment paper for easy removal.
  2. Blend Oats: Pulse oats in a food processor until they resemble coarse flour.
  3. Mix Ingredients: Add the rest of the bar ingredients. Pulse until it forms a thick dough.
  4. Press Into Pan: Transfer the dough to the pan. Press it down firmly and evenly.
  5. Optional Chocolate Drizzle: Melt chocolate chips with oil, then drizzle over the bars.Chill: Refrigerate for about an hour until firm.
  6. Cut and Serve: Lift out the set bars using the parchment, slice them, and enjoy.
  7. Store: Keep in a sealed container in the fridge.

It doesn’t get much easier than that!

Is Making Your Own Protein Bars Cheaper?

Yes, making your own protein bars is usually cheaper. Buying the ingredients might cost more at first, but you can make a lot of bars, which saves money over time.

Store-bought bars usually cost between $1.50 and $3.00 each. Making them at home can be cheaper, depending on what ingredients you buy.

Also, you can choose all-natural ingredients and know exactly what’s in your bars. Plus, you can easily change the recipe to be exactly how you like things!

Ingredients In Homemade Protein Bars

  • Old-fashioned oats: Give the bars shape and a chewy texture.
  • Peanut butter: Smooth works best. Stir natural peanut butter first. 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: Affects flavor and texture. Use one you like. Add more honey if needed.
  • Mini chocolate chips: Use dark chocolate for less sweetness.
  • Optional chocolate drizzle: Skip for a simpler bar.

Homemade Protein Bars Tips

Here are some tips for whipping up the best possible homemade protein bars:

  • Adjust Sweetness: If your protein powder is already sweet, use less honey. You can add more later if needed.
  • Check for Salt: Some protein powders have salt. Taste before adding extra.
  • Pick a Nut Butter You Like: Use one you enjoy straight from the jar—it’ll taste great in these bars.
  • Press Down Firmly: Pack the dough tightly in the pan with a measuring cup for an even layer.
  • Line the Pan: Use parchment paper so the bars come out easily.

    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
