Sift the protein powder, cocoa powder, coconut flour, cinnamon, baking powder and salt, and set aside – don’t skip this step because it keeps the protein powder and coconut flour from globbing together into lumps.
Beat the butter and brown rice syrup with a hand mixer until creamy.
Whisk in the eggs and vanilla.
Gently stir in the sifted dry ingredients, combining thoroughly.
Mix in the shredded coconut, dates and zucchini until well combined.
Spread batter into a greased, 8″ x 8″ pan.
Bake at 350 degrees for 35-40 minutes.
Let cool 5-10 minutes.
