First make the Chocolate Cream Pie Cookie Cups if you are using those for this cake.
Next preheat the oven to 350°F & grease & parchment line your 4-7" cake pans
Prepare the chocolate cake recipe as per the instructions on that blog post & bake the layers into 4-7" pans *If you only have 8" pans you can divide the batter evenly between 2 or 3- 8" pans
While the cake is cooling, prepare the custard by combining plant milk, sugar & cornstarch in a medium sauce pot over medium to high heat. Bring to a boil stirring constantly to avoid scorching the bottom .
Once it starts to bubble remove from the heat & add the vegan butter & the chocolate, stir to melt evenly throughout then add the vanilla extract.
Pour into a heatproof bowl to cool while you prepare the chocolate ganache recipe
Prepare the chocolate buttercream recipe according to the instructions on that recipe post & reserve
To make chocolate whipped cream add about ¼ cup of COOLED ganache to the whipped cream at the last stage of whipping. This works for SILK brand, Country Crock & my homemade recipe
