Directions

For the Cake Magic! Cake Mix:

  1. Place all of the ingredients in a large bowl and whisk together well to combine. Whisk the mix again before measuring. It’s important to use table salt in the cake mix; other types will eventually settle out of the mix.

For turning it into the Darkest Chocolate Cake:

  1. Preheat the oven to 350° F. Butter the bottom and sides of the pan(s). Dust with cocoa powder to coat, then invert and gently tap out any excess. (If making cupcakes, use liners instead of greasing and coating the tins.)
  2. Whisk together the 1⁄2 cup cocoa powder, cake mix, and baking soda in a large bowl to combine. Stir in the melted chocolate, yogurt, butter, water (or cola!), and eggs until moistened and no lumps remain (be careful not to overmix). Divide the batter between the prepared pans.
  3. Bake until the layers are domed and fragrant, and a few moist crumbs cling to a skewer inserted in the center of the cake, 35 to 40 minutes (40 to 50 minutes for a Bundt, 25 to 30 minutes for a 9- by 13-inch cake, and 20 to 25 minutes for cupcakes).
  4. At this point, coat the layers with syrup (https://food52.com/recipes/60584-vanilla-syrup-mixed-berry-syrup-sweet-cream-syrup-variations). After removing the hot cake layers from the oven, pierce them, still in their pans, at one-inch intervals with a skewer or paring knife. This creates channels for the syrup to seep into the cakes. Then, pour or generously brush the syrup over the surface of the hot layers, dividing it between them as evenly as you can. Transfer the soaked layers (still in their pans) to a wire rack to cool completely.
  5. When they are cooled and no longer wet to the touch, one to two hours, carefully turn them out of their pans and assemble and frost.

Wonderful chocolate cake. ( No cola!) Moist but light, and very chocolatey. My family likes it as much as our other favorite recipe that's more work. I use cake flour rather than AP, and have converted the basic mix to weights. Make 2x batches.

Can't believe a cake book doesn't use weights - so much easier than getting cups dirty. Does the book use weights?

OMG This is the BEST cake ever. I used Coca-cola and the cake is SO fluffy & chocolaty. Thank you for sharing. Cheers. <br />
