Preheat the oven to 325 degrees F. Spray a 9×13 inch dish with nonstick spray.
In a large bowl, combine the oats, flour, pistachios, almond flour, coconut, brown sugar and baking soda. Stir well to mix.
In a saucepan, combine the butter, coconut oil, honey and vanilla bean paste. Heat over low heat until the butter and oil melts, stirring the mixture together. Pour the butter mixture over the dry ingredients, stirring well until the entire thing is moistened. You don’t want any dry oat parts. Press the mixture in the greased dish and smooth the top with the back of a spoon. Bake for 18 minutes, or until the top is slightly golden and the bars are set. Allow to cool completely before slicing into bars. You can drizzle the chocolate on top before or after cutting – you can also dip them.
