Toast your pecans and coconut; let cool. Melt the butter and let cool.
Whisk together melted butter and brown sugar in a large mixing bowl. Add eggs and vanilla and mix well.
Combine flour, baking powder, and salt in a small bowl. Stir into creamed mixture. Add nuts, coconut, and chips.
Spread into a well greased and parchment lined 9x13" pan.
Bake at 350° for about 22-25 minutes. Top will be shiny and golden brown. Don't over-bake!
Notes
To toast pecans - bake cold pecans for 10-12 minutes at 375 degrees or until lightly browned. If they are room temperature, you’ll only need 7-8 minutes
Coconut will only take 5-7 minutes at 375°. Watch it closely and stir often.
