The variety of things you can use in these chewy and tasty granola bars is endless! The only important thing to know is the base – oats, honey/syrup, brown sugar and butter. After that, its completely up to you. Here are some of my suggestions for additions to granola bars that produce a wonderful flavor.

  • almonds, pecan nuts
  • dried cranberries, apricots, coconut (unsweetened)
  • pumpkin, seasame seeds
  • peanut butter

Important things to know before making this Peanut Butter Granola Bar Recipe

Press the mixture firmly in to the pan

This is a really important step. The first time I made these, I didn’t press hard enough and ended up with a mixture of granola instead of granola bars. But hey, now I know how to make granola also. If it’s compact bars you’re after that actually keep their shape, press the mixture hard in to the pan for at least a minute before refrigerating.

Easily adapted

As already pointed out above, the best part about this recipe is you can really add anything you want. Have fun adding new flavors like cinnamon powder or add some dark chocolate chips. You wont know until you try!

The ‘Glue’ for the granola bars is important

You need a glue to bind all the ingredients together. This is where the honey, butter and brown sugar comes in. It creates a sticky liquid that is then added to the dry ingredients and helps everything stay together. That said, I try to keep most of my recipes healthy and I usually leave the brown sugar out. I have made these bars with and without sugar and I can promise you they are sweet enough even without the sugar, especially if you are adding things like sweetened peanut butter, chocolate chips, or coconut. They are a little more crumbly without sugar but the health benefit of not using sugar outweighs a perfect looking granola bar in my opinion. It’s up to you!

Refrigerate before cutting

You may be impatient to dive in and sample the mixture but it’s important to allow it to set for at least 2 hours in the refrigerator before cutting the granola in to bars. Once out the refrigerator, they will soften and become chewier but it’s essential that you cut them in to bars when they are hard and straight out the fridge.
