Firstly, line two bread pans with parchment paper. The size of the bread pans can vary, smaller bread pans will give a thicker granola bar, and a larger bread pan will give a thinner granola bar size.

In a medium pot add butter, honey, peanut butter, and brown sugar. Stir to combine.

Then, turn heat on to medium heat, and cook until the sugar mixture melts and starts to bubble up, this should only take a short time. Once it bubbles up, turn off the heat.

Stir in the vanilla extract and pinch of salt. Mix to combine.

If adding cinnamon, stir that in.

Then, add the rolled oats and mix.

Next add in the crisp rice cereal and mix.

If using seeds or nuts, add in and mix.

Once everything is incorporated, then pour the mixture into two lined bread pans.

Sprinkle the top of the mixture with chocolate chips if using. Then using the excess parchment paper, fold it over the top of the granola bar mixture and press it into the pan to flatten the mix. You want to press it in pretty firm.

Place both pans in the fridge to cool. Allow 1 to 2 hours in the fridge before cutting.

Lastly, enjoy!
