Preheat the oven to 350f (180c) and line bottom and sides of an 8×8-inch pan with parchment paper.
Using a mixer, cream together the butter and brown sugar. Add the flour and salt and mix until crumbly. Press the crust into the pan and bake 15 to 20 minutes until golden.
While the crust bakes, prepare the filling by combining the butter, brown sugar, maple syrup, cream, and egg in a mixing bowl. Use a whisk to combine. Add pecans and chocolate; mix. Remove the crust from the oven and immediately pour the pecan filling over the hot crust spreading it to cover the entire surface.
