The Ultimate Double Chocolate Cake Recipe (The Secret Ingredient Is Love)

Ever since my husband was a little boy, he’s had a chocolate cake for his birthday – first baked by his mother and then purchased at a local bakery that made the most decadent cakes imaginable. There was no use for me, the non-baker, to try to improve on that (or at least that’s what I told myself)! I didn’t even own a cake pan, for goodness sakes!

However, when we moved out of state, away from his mom and that bake shop, it was time for me to leave those sad excuses (and my Duncan Hines box mix) behind and learn to bake a birthday cake for him. Finding two good cake pans for $5 at a nearby thrift store, I located an easy one-bowl chocolate cake recipe on the internet, asked my mother-in-law for her special recipe for frosting, dusted off my ancient mixer and got to work. A few hours and a kitchen covered with cocoa powder later, I had a beautiful, pretty tasty chocolate-on-chocolate cake that also passed muster with the discriminating birthday boy.

Before you get started making this rich chocolate cake recipe, make sure your kitchen is stocked with all the ingredients (personally, I forgot to check my supply of powdered sugar!), but especially the most important one: LOVE!

Recipe Notes

  • If you don’t have corn syrup in your pantry, you can substitute molasses or honey, but it will give the frosting a slightly different flavor.
  • Use a large bowl for the frosting. Otherwise, you’ll have cocoa powder everywhere (like I did)!
  • Make sure to grease and flour pans (including the sides) well.
  • To release the cakes from the pans, place the cooling rack on top and flip the pan over. If the cake doesn’t pop out easily, run a knife around the edges of the pan and if that doesn’t work, slide forks gently underneath to partially release the bottom.
  • Be sure layers are evenly stacked one on top of the other.
  • Don’t scrimp on frosting between layers.
  • Do not refrigerate the frosting. It will be too hard and cause the cake to crumble when frosting.

Here’s how to make it:

  1. To make the cake, mix all the dry ingredients together.
  2. Beat the eggs (I used my mixing cup for beating) and add them along with the milk, oil and vanilla to the dry ingredients and beat for about 2 minutes until well-blended.
  3. Stir in the boiling water. The batter will be thin.
  4. Pour evenly into two greased and floured cake pans. Bake in preheated 350-degree F oven for 30 to 35 minutes or until a toothpick in the center comes out clean.
  5. Cool in pans for about 10 minutes. Remove cakes from pans and cool completely on wire racks to prepare for frosting.
  6. To make the frosting, in large bowl, beat butter and cocoa powder and a teaspoon or two of the corn syrup to make beating easier. Add the rest of the corn syrup and continue beating until smooth. Gradually add the boiling water and beat in. Stir in vanilla and salt. Once all of the other ingredients are blended, slowly add the powdered sugar to the mixture, beating on high until smooth.
  7. Once the cakes are completely cool, frost the top of one layer. Carefully place the second cake on top and then frost the outside of the whole cake.
