To make the oatmeal cookie layer, mix the flour, baking soda, brown sugar and oats together in a large bowl. Pour the melted butter over the mixture and mix until well combined.

For the brownie layer, cream butter, sugar, eggs and vanilla together for 2-3 minutes in a large bowl.
In a separate bowl, combine the flour, salt, baking soda, and cocoa powder. Add to the creamed mixture and mix just until combined. Pour the brownie batter over the oatmeal crust.
