Homemade Protein Granola Bars – Ditch Store-Bought for These!

If you’re tired of overpriced store-bought granola bars that claim to be “healthy” but are packed with sugar and questionable ingredients, it’s time to make your own! These homemade protein granola bars are chewy, perfectly sweet, and loaded with good-for-you ingredients like oats, peanuts, flaxseed, and protein powder.

The best part? My kids devoured them. I was honestly shocked when Emrie asked for another one (because let’s be real, kids are the harshest critics). These bars are now a staple in our house because they’re the perfect balance of sweet, chocolatey, and protein-packed—aka, a mom win and a kid-approved treat.

Why You’ll Love These Granola Bars

  •  Packed with Protein – Thanks to protein powder, eggs, and peanuts, these bars have 8g of protein each!
  •  No Junk Ingredients – Unlike store-bought bars, these have simple, whole ingredients you can actually pronounce.
  •  Easy to Make – One bowl, 10 minutes of prep, and done!
  •  Customizable – Make them nut-free, dairy-free, or switch up the flavors to fit your family’s taste.

Tips & Variations:

• Swap the peanuts for almonds or cashews.

• Use peanut butter instead of butter for extra flavor.

• Drizzle with melted dark chocolate for a treat.

• Make them dairy-free by using plant-based milk and coconut oil instead of butter.

These bars are the perfect balance of protein, healthy fats, and natural sweetness—great for meal prep and busy mornings!
