In a large bowl, add the sugar, lemon, baking powder, baking soda and salt and give the mixture a couple of good whisks to combine. Add in the eggs, vanilla, coconut extract and whisk until the mixture is light and frothy, about 2 to 3 minutes. Slowly add in the oil, whisking until fully combined (set the bowl on a towel to keep it from moving about). Alternate adding the flour and water in two additions, whisking each until just combined. Fold in the unsweetened coconut. Let the cake batter sit for 5-10 minutes.
