Heat the nut butter and honey over medium heat until melted. If you are using vanilla, it can be added in this step as well.
Once the butter and honey is a smooth, consistent texture, add in the oats and any other dry ingredients. Stir to combine until all dry ingredients are coated in the butter and honey mixture. If you chose to use chocolate chips, they may partially or completely melt during this step.*If using add-ins such as nuts, seeds, fruit, etc. sub out 1/2 cup of oats. Pack the mixture in a parchment lined 9"x13" pan and refrigerate. Once the pan is cool, cut into 24 bars.
Store in an airtight container in the fridge or freeze.
