Preheat oven to 350 degrees F.Using a mixer, blend the room temperature butter until smoothed. Toss in the Swerve sweetener and cream until well blended. Blend in the eggs, vanilla extract and apple cider vinegar. Set aside.In a large bowl, mix together the dry ingredients of coconut flour, baking powder, baking soda, cinnamon, nutmeg, granulated Stevia extract and salt. Set aside.Using a cheese grater or food processor, take the zucchini and grate to a fine texture. I prefer to use a food process for this step.Take the zucchini to the sink and drain out some of the excess moisture. (optional)Before adding in the zucchini, first slowly add in the dry ingredients with the wet ingredients and blend until fully mixed. Then, mix in the zucchini until well blended.Grease a loaf pan, and add in the batter.Bake for a minimum of 30 minutes and keep checking until baked fully. If doubling the loaf like I do, it tends to be fully baked around 50-60 minutes.
