If you are making the box cake hack recipe you will follow the instructions for yellow cake but instead substitute in the white cake box mix
Preheat the oven to 350℉ then grease & parchment 3-7" cake pans
For the scratch white cake recipe as listed above~ first add the vinegar to the plant milk & then add the vanilla extract
For the egg replacer I typically do not reconstitute it as the packaging will advise, but rather add it to the dry ingredients (unless I am using flax meal then I reconstitute with some liquid from the recipe)
Next place all of the cake ingredients except for the sprinkles into a large mixing bowl with a hand whisk combine everything & whisk smooth, approximately 50 strokes to develop the batter
Add in the sprinkles, folding to combine well
Pour batter evenly amongst the prepared cake pans
Bake in a preheated oven at 350°F for 25-30 minutes or until a toothpick inserted into the center comes out clean.
Cool the cakes in the pans until you can safely flip them onto a cooling rack to cool to cold
Refrigerate while you prepare the buttercream recipe according to the directions on that recipe post
See video tutorial for comparing the Betty Crocker canned icing vs the homemade buttercream for the drip effect & decide which way you prefer
Add food color to approximately ½ cup of whatever icing you are using then heat in the microwave for just 10 seconds until it is pour able consistency
The Betty Crocker canned icing was perfect at 10 seconds, however if you watched the video you will see the homemade buttercream icing needed a few seconds more *be careful not to melt it!
