To Make No Bake Granola Bars You Will Need:

  • Peanut Butter – It’s best to use smooth peanut butter for this recipe, and I haven’t test it with a natural peanut butter. However, if you want to give it a try and experiment, feel free! Learn how to make peanut butter here.
  • Honey – Honey adds natural sweetness to the bars and eliminates the need to use refined sugar.
  • Old Fashioned Oats – If you are celiac, opt for Bob’s Red Mill Gluten Free Old Fashioned Oats. Oats are gluten free, but can be exposed to cross-contamination because they’re often processed in the same facility as wheat. 
  • Puffed Rice – To add texture and crispiness to the bars. You can use white or brown puffed rice.

How Do You Get Granola Bars To Stick Together?

The honey and peanut butter in these no bake granola bars helps to bind all of the ingredients together, and when chilled they become firm and hold together really well.

Make sure that the mixture is really well mixed and be sure to press it down firmly into the sheet pan before chilling it overnight.

breakfast bar idea - easy no bake granola bars with a toppings bar to customize your own

Through the years I’ve focused on a more effortless style of entertaining which feels thoughtful, beautiful and anything but stressful. I love serving a simple toppings bar so that guests can customize to their preference, especially for breakfast and brunch when you have a limited amount of time to prepare.

Are you a picky eater? My palate has expanded tremendously as I’ve grown older, but I’m always in favor of customizing. It feels more appealing than option A or B, doesn’t it? Offering granola bars with a toppings bar is an easy but beautiful way to serve breakfast or brunch for a few or a crowd and requires very little effort.

You can set up a granola bar toppings bar on a buffet or bar cart, but when hosting an intimate get together, I prefer to display directly on the table for convenience. It also doubles as an instant centerpiece!

Tips 

  • Store – Granola bars keep them refrigerated for up to a week. They are great to make on a Sunday evening and then enjoy them throughout the week.
  • These bars freeze really well. Once the bars have chilled and you have cut them, freeze them in an airtight container with the layers separated by parchment. Thaw to room temperature to enjoy.
  • Use gluten-free certified oats to make these bars gluten-free.
  • You can make these bars vegan by swapping the honey for maple syrup. I haven’t made them this way, but pretty sure they will turn out well!

  1. This look good and easy. A question. Are you using crispy puffed rice (like Rice Krispies) or the spongy/soft type of puffed rice?  Thank you. 

  2. 5 stars
    Made these this afternoon and they are yummy!! I used almond butter instead because I am not a peanut butter fan.  Would you recommend continuing to store them in the fridge after cutting? 

  3. I am a huge granola bar fan because I am always on the run, especially when I am running late into the office! so I would love to make these! Thanks for sharing!
