Preheat the oven to 350 degrees. Line an 8-inch square baking pan with aluminum foil and grease foil with either butter or vegetable shortening.
Melt the canna-butter over low heat in a medium saucepan. Set aside to cool for 5 minutes.
Stir together the flour and salt, set aside.
Stir the brown sugar into the melted cannabutter until well combined.
Beat in the egg and vanilla and continue mixing until well incorporated.
Mix in the flour and salt until just incorporated.
Stir in the chocolate chips and pecans until blended in evenly.
Spread batter into prepared pan and bake for about 25 to 30 minutes or until a toothpick inserted in the center comes out with just a few moist crumbs clinging to it. (Note: batter will be thick.)
Let cool in pan before using the foil to lift out the brownies and slice.
