Preheat the oven to 350℉ & grease & parchment line 3-7" cake pans
Make the coconut cake by combining all the wet ingredients together in a measuring cup
Sift all the dry ingredients together in a larger bowl *including the sugar & dry blend egg replacer- I do not reconstitute
Add the wet ingredients to the dry & whisk smooth then add the flaked coconut
Bake for approximately 30 minutes or when you gently press the centers they are springy to the touch
Cool in the pans while you prepare the buttercream recipe as per the instructions on that post
Divide the buttercream by separating 2 cups for the filling then add the freeze dried raspberry powder to that. The remaining buttercream is for the icing
Next prepare the lemon custard by whisking the sugar with the cornstarch in a small bowl, then add it to a medium sauce pot along with the water, lemon juice, zest & plant milk
Bring it up to a rolling boil whisking constantly to prevent scorching on the bottom
Once it boils fully add the lemon zest & stir for 10 seconds then remove from the heat & reserve
Once your cakes are fully cooled & preferably COLD set up the ring mold build method as shown in the video linked here
Layering with the cake/raspberry buttercream/slightly cooled lemon custard so you won't melt the buttercream! then repeat until you have a 3 layer cake
Refrigerate for at least an hour or until firm & set then ice with the remaining buttercream & cover the entire cake with flaked coconut & optional raspberries for garnish
