Preheat oven to 350 degrees F. Grease and line a 9x9" metal baking pan with parchment paper.
In a large mixing bowl, mix coconut oil, honey, tahini, and miso.
Add oatmeal and stir well to coat all the oats.
Mix in the chocolate chips until evenly dispersed.
Transfer mixture to your prepared baking pan and with wet hands or a rubber spatula, firmly press into the pan, leveling off the top.
Bake in your preheated oven for 20-25 minutes or until the edges and surface are a light golden brown. Allow to cool completely before slicing into bars. Leftovers can be kept in an airtight container at room temperature, but I recommend storing in the fridge to allow the bars to set and solidify well.
