These tasty granola bars are only 5 ingredients! Filled with healthy fats and hearty whole grains, these are a filling and delicious snack!

There are plenty of granola bars at the grocery store but many of them are filled with sugar, preservatives, artificial flavors, and other things I don’t need in a snack. There are some great options out there on the market but the natural ones can be a little pricey so making your own is a nice way to keep your grocery costs down! I know almond meal can be a little expensive so if you don’t want to buy it, you can replace the almond meal with more oats.

5 Ingredient Granola Bar Substitution Ideas

  • Feel free to use agave, honey, or even maple syrup. Any liquid sweetener is fine, but keep in mind that honey isn’t considered vegan. So if you’re making them for a vegan friend, stick with agave or maple syrup!
  • If you want to keep these granola bars gluten-free, be sure your oats are gluten-free. Some brands are and some brands aren’t!
  • I like using chunky peanut butter but you can use smooth if that’s what you have on hand!

I love the texture of these granola bars because they’re chewy and crunchy all at the same time! They also just happen to be gluten-free & vegan. If you don’t have peanut butter, sub in almond butter. If you don’t have sliced almonds, sub in more oats. The great thing about these granola bars is you can really make them with whatever you have in your pantry.

These tasty granola bars are only 5 ingredients! Filled with healthy fats and hearty whole grains, these are a filling and delicious snack!


  • 1/3 cup agave (or honey, if not vegan)

I’m thinking these would also be great with chocolate chips or coconut flakes!
