Whisk the milk and apple cider vinegar in a large bowl. Set aside for a few minutes to curdle
Add the sugar, oil and vanilla to the milk mixture. Sift in the dry ingredients and beat until there are no large lumps left (small ones are fine)
Evenly separate into three batches (two extra bowls) and add your additional ingredients for a vanilla, chocolate, and lemon cake
Pour each batch into a tin can and bake for 40 minutes or until a toothpick comes out clean. When ready, transfer to a cooling rack and let it cool completely before cutting the cake into three parts
Spread a generous amount of icing on each cake slice and layer.
Icing
Cream the butter thoroughly using a stand mixer or hand blender. ½C at a time, add the icing sugar and keep mixing until you get your desired icing texture.
If it becomes to stiff, mix in a tbsp of water at a time to make your icing softer.
Separate into three batches (two bowls) and add the additional ingredients for mint, chocolate, and cream cheese icing. Mix thoroughly
