I unofficially dub this the snack-iest that a snack bar could possibly be with granola (a snack) turned into a SunButter Granola Slice (another even yummier snack). Shoutout to our supporting snack characters – banana, SunButter, cinnamon, and a myriad of seeds – for making this snack inception moment extra sweet and wholesome.

How To Make a Granola Slice

When I say granola SLICE I want you to think: granola bar but thicker with a cross section that’s a little more showy when you slice in and a creamy top coating to create that layer effect that is essential for any sort of slice. So similar yes, but with a few differences you will see along the way…

Ingredients For The Yummiest Nut-Free Snack

  • Granola. Obviously necessary, and a simple neutral flavored option is best (i.e. not chocolate or overly flavored, not too fruity or chunky)
  • Seeds. I used a mix of sunflower, pumpkin, and flax. You could swap in chia or hemp too.
  • Crispy rice cereal. Toasted not puffed please, and I prefer brown rice personally.
  • Cinnamon and salt. And any other spices you’d like to add in.
  • Banana. This is our only “sweetener” so make sure they are really ripe.
  • Creamy SunButter. Our glue, our fat source, our flavor, our favorite seed butter: SunButter! So a very essential ingredient in the granola layer, but save some for the creamy topping too.

There is a bit of flexibility in this recipe, so don’t be afraid to customize. Swap the seeds around. Swap in chopped nuts if you don’t need it to be nut-free. Get a little granola slice wild and use Chocolate SunButter for an entirely different flavor profile even.

A Few Technique Tips

  1. Blend the granola. As much as I LOVE an oversized granola cluster, for this recipe you want small granola pieces only or they bars won’t hold together properly. So if your granola is extra chunky, just pulse it in the blender or food processor briefly before you begin.
  2. Really PRESS it into the pan. You want a granola SLICE not a granola crumble, so press your mixture into the pan very firmly pre baking. And then again post baking since it will puff up a bit in the oven. Or better yet, place something heavy on top while it cools to really smush everything together.
  3. Let the granola layer cool for about 30 minutes before adding the topping. Then chill everything for 4+ hours (or ideally overnight!)
  4. To get the smoothest top surface, simply shake the pan to spread the topping into every corner. I promise it will turn out much smoother than spreading.
