Preheat oven to 350F.
In a large bowl, cream butter (or coconut oil) and coconut sugar. Once well creamed, add eggs and vanilla. Continue mixing until smooth and creamy.
With mixer off, add in almond flour, baking powder, and salt. Mix until well combined. (You may want to scrape the bottom of the bowl and then mix again for approximately 30 seconds to get everything).
Gently stir in chocolate chips and macadamia nuts.
Spread batter in a prepared 8x8 baking dish, then bake for 25 minutes or until toothpick inserted comes out clean.
Allow to cool completely before slicing. (This is vital, and you will be sad if you don't).
Serve and enjoy!
