Preheat the oven to 350 degrees F. Spray a 9x9 square pan with cooking spray.
In a medium-sized bowl, whisk eggs. Stir in the melted butter, sugar, salt, vanilla and melted chocolate chips.
Add the cocoa powder, almond flour and baking powder and stir to combine.
Scoop/pour the batter into the prepared pan, spreading it to the edges.
Bake brownies in the oven for 20 minutes.
While brownies are baking prepare topping by combining brown sugar, maple syrup, melted butter, egg, vanilla, salt and pecans in a small bowl.
After 20 minutes, remove brownies from the oven and evenly spread the pecan topping over the brownie batter. Place back in the oven and bake for 20 minutes or until the topping has set. Remove from oven and let brownies cool for about 15 minutes before slicing and serving.
Brownies will keep for 2 days covered at room temp or up to 5 days in the fridge.
