In a large bowl, combine the rolled oats, almond butter, honey, melted coconut oil, vanilla extract, and salt. Mix well until everything is thoroughly combined.
Press the mixture evenly into the prepared baking pan.
In a small bowl, melt the chocolate chips and coconut oil together. You can do this in the microwave in 30-second intervals, stirring in between, or over a double boiler.
Pour the melted chocolate over the oat mixture and spread it evenly to cover the entire surface.
Place the pan in the refrigerator for at least 30 minutes, or until the chocolate is firm.
Once firm, lift the bars out of the pan using the parchment paper and cut them into squares.
Store the bars in an airtight container in the refrigerator.
