Preheat your oven to 350°F & prepare an 9" x 9" cake pan with parchment paper lining & pan grease
Lightly toast the coconut in a single layer on a sheet pan in the oven for 5-10 minutes
In a large bowl combine the sugar with the plant milk, oil, orange juice, zest & salt & whisk smooth
Sift together all of the dry ingredients directly into the sugar/oil mixture in the bowl & whisk smooth
Fold in the carrots, pineapple & coconut & mix smooth
Pour the batter into the prepared pan & bake immediately. Approximately 30 minutes or when the cake is springy to the touch when you gently press the center
Cool in the pan until then flip out onto a cooling rack to cool completely
Meanwhile prepare the cream cheese icing according to the recipe on that post
Assemble the cake as shown in the video or as you desire
