Mix the cake powder with the coke well till fully incorporated and you have this floofy batter.
Spread out into a parchment lined, well sprayed pan. Bang it a few times to let out the air bubbles and then bake in 350F for 20-25 minutes.
Let cool while you make the frosting.
Whisk together all the frosting ingredients till smooth and then spread onto your cake.
Then serve!
