In a large bowl, add all of the dry ingredients (up to honey) and stir to combine.
In a small saucepan, add the honey and peanut butter. Cook on medium heat until mixture bubbles, stirring frequently. Remove from heat and let cool slightly. Then add the vanilla.
Add the wet mixture to the dry ingredients and stir well. The mixture should get quite thick.
Add the grated carrot and raisins. Stir well to combine.
Line an 8x8 baking pan with parchment paper. Scoop the granola bar mixture into the pan.
Pat the granola mixture down as much as you can! Adding a sheet of parchment paper on top can help prevent the mixture from sticking to your spatula or spoon. You can also press it down with your hands. The more it is pressed down the better they will stick together!
Place in the fridge for at least 30 -60 minutes to allow bars to set. Then slice into bars.
Store the bars in an airtight container and keep in the fridge for 5-7 days or in the freezer for a month.
