Firstly, take three 6 inches or 8 inch round cake pans and grease them with little butter, then dust them with all-purpose flour and keep them aside. This step ease your effort to make the sponge base out of the pans after baking
In a large bowl, add 1 ½ cups of all-purpose flour, 1 tsp of kosher salt, 1 tsp of baking soda, mix well and set aside
In another bowl, take ½ cup of room temperature butter and beat it
Now add 1 ½ cup of granulated sugar and beat more
Add 3 eggs while continuing beating
Now add2 tsp of vanilla in it and beat to mix well
In a separate jar, add 1 cup of room temperature buttermilk, 1 tbsp of vinegar, a few drops of red gel food colouring, and mix all the ingredients well to make a bright red colour liquid
Now come to that bowl of batter, after vanilla extract, add 2 tbsp of cocoa powder (one tbsp at a time) through sieving and mix well
Now add half of the dry flour mixture and mix everything evenly, now add half of the red mixture while beating
Repeat the process for half of the dry flour mixture and red mixture
Now divide the batter into that three cake pans evenly
Also, fill 1 cupcake mold with the cake batter, add some more drops of red gel food colouring, mix well and bake for 15 minutes in an oven to make crumbs for dressing later
Now bake that pans at 350o F for 30-35 minutes
Take out the pans, let them cool for a while
Now to take them out, tap the sides of the pan and flip them over the wreck or plate, so that the perfect base comes out
