Preheat your oven to 325 degrees f. and line an 8-inch square baking pan with parchment paper.
In a large bowl add all your dry ingredients and stir to combine well.
Melt your peanut butter gently on LOW heat using a saucepan or microwave. Stir it very often, and check on it every few seconds.
In a second smaller bowl, add your wet ingredients and whisk together well until smooth.
Pour your wet ingredients over the dry ingredients using a spatula to get it all. Stir everything until well combined, then transfer your mixture to the prepared baking pan.
Firmly press the mixture into an evenly-packed layer.
Place into your preheated oven and bake for about 25-27 minutes, or just until it begins to get a nice golden color on top.
Once done remove from the oven, and allow to completely cool down.
Your bars will firm up more as they cool, so slice them once they're completely cool.
Enjoy!
