I love to whip up a cake from scratch.  Everything goes into one bowl and gets whipped up in no time at all.

You all know how I love to tweak recipes just a little.  I’d been seeing lots of buttermilk cake recipes recently.  So that got me thinking…..

Chocolate Buttermilk Pound Cake?

Instead of sour milk, like the original recipe called for, why not buttermilkCakes made with buttermilk have an extra rich flavour, and I remember growing up how much my Dad loved buttermilk!

Desserts made with buttermilk were really popular in our home.

And of course I wanted to created the very BEST buttermilk chocolate pound cake ever!

For this Chocolate Buttermilk Bundt Cake recipe, the addition of a cup of hot water along with the cup of buttermilk and a cup of oil, makes for a very moist cake!

And that of course contributes to one very yummy cake!

  • You can make this in a 13 X 9 pan, or use a Bundt (10″ X 4″) pan.  Sue made hers in a 13 X 9, so I thought I would try the Bundt.  
  • Follow all of the instructions carefully
  • Make sure you line whatever pan you use and grease it really well (butter or shortening and I usually use aluminum foil to line the pan).
  • Once the cake is baked and cools, invert the pan on a platter or plate so that you can peel away the foil and then set it right side up.
  • Make the hot water frosting right away so that lovely warm chocolate can cover your deliciously moist chocolate buttermilk bundt cake.
