In a medium sized pot, add in your butter on a medium/low heat. Let it melt slowly and incorporate your sugar, honey and vanilla. Stir constantly and bring up the heat to a medium/high. We want the mixture to start bubbling.
Once the mixture is bubbly and foaming, turn the heat off and stir until the bubbles settle. Add in your remaining ingredients, minus the chocolate chips, and stir in between each ingredient incorporation.
Once everything is well combined and still warm, grab your rectangular or square form of choice to press your granola bars into. I like using two 5x10 bread loaf pans, lining them with parchment paper.
Split your granola bar mixture between the two pans and using a buttered or greased back spoon, work to firmly press the mixture down. We want it quite compacted so these bars stay together once they are cut.
Grab your mini chocolate chips and sprinkle them on top of the granola mixture and push them in gently.
Cover the bars and set them in the fridge for an hour to harden.
Remove from the fridge and take the granola mixture from the containers. Use a sharp knife to cut them into bar shapes. I usually get about 14 bars from one batch!
Store in an airtight container in the fridge or a cool place. If stacking, place a piece of parchment in between layers to prevent sticking. Keeps for 7-10 days.
