Buttermilk Chocolate Cake with Fudge Icing

Recipe by  

"This is the simplest and moistest chocolate cake I have ever found and was a favorite when I grew up. I could even whip it up as a child. This cake is also great with the boxed fluffy icing so the great chocolate flavor of the cake is not hidden."

This cake should have 10 stars!!! I made it for my husband's birthday last night. I used a bundt pan (dusting with cocoa powder in lieu of flour) which required about an 20 minutes extra baking time. I then let the cake cool for a few minutes in the pan, and then took it out of the pan to finish cooling while I made the frosting. After the frosting was done, I put the cake back into the bundt pan and then poked holes in the bottom of the cake with a wooden spoon and a fork. I then poured about half the frosting into the holes. I would have let it sit like that for awhile but my husband was coming home so almost immediately I put the cake on the serving plate and then using a basting brush, painted the rest of the frosting onto the top of the cake. Gobs of frosting still pooled into the "hole" of the bundt cake. When my husband took the first bite, he exclaimed - "Oh My God! It's filled with chocolate!" I ***strongly*** recommend using the highest quality of cocoa powder available as it is the only chocolate in the cake. I used Ghiradelli. Also, the batter was quite runny when I poured it into the pan but it cooked up just fine. I also "made" my own buttermilk by adding 1 T. apple cider vinegar to 1 c. milk and letting it set for a few minutes. I also used 1/4 c. cocoa powder in the cake as opposed to just 3 T.. Amazing recipe!

The cake wasn't horrible but it wasn't the best that I've had. It was moist as other users have said but you would definitely want to add more cocoa..I used 1/4 cup..I would also recommend sifting the flour before use or use cake flour.

I've never made the cake, but I have made the fudge icing and used it on other cakes. It is delicious and truly tastes like fudge. I would caution, however, that you do not beat it for the full 3 minutes if you intend to pour it over your cake (I like it poured over bundt cake). It will not flow down the sides but rather sit on the top in more of a clump. Stop beating when it looks a little thinner than what you want because it will set very fast.

After reading the reviews I decided to make a few small changes and made this a 5 star recipe (well at least to me). I added 1/4 cup of cocoa powder instead of the 3T and an extra tsp of vanilla. Also I didn't have buttermilk so I added a tsp of vinegar to a cup of regular milk. The icing was very yummy even though I burnt it while boiling. I saved it by just pouring off the good stuff and not scaping the bottom of the pot. Also I only beat it for 2 min and didn't have any problems with it being too thick. SUPER DUPER and very moist!

This cake is divine! So moist and tasty. Do not skip the frosting step, it compliments the cake perfectly - it is just not the same cake without it. I have made this cake several times and it has been consistently successful. Just a couple of suggestions: I use a little over 1/4 cup of cocoa powder, instead of 3 tbls. Do not burn your frosting. Properly butter and flour your pan beforehand (I use a 9X13 pan). Do NOT overbake. Take out while still slightly moist on the toothpick (not clean like the recipe says). I shut off oven and let the cake sit in for 5 min max after the slighly moist point. and ENJOY!!!

Flavor is excellent. I only gave it 4 stars however, because I want more frosting. I took a photo, which shows how the frosting doesn't cover the entire cake. Sure, it is rich, and sweet... but I *like* chocolate cake that way! The more the better!! I did follow someone else's suggestion of using 1/4 Cup of Cocoa for the cake batter, and am glad I did. Now I'm off to make another batch of frosting - yum! -

This recipe is fantastic! Every chocolate cake I've ever made has come out dry but this one was perfect! and so easy! I beat it by hand not with a mixer and used a chocolate buttercream frosting. Ummmm! good! But beware, you'll be coming back for 2nds and 3rds and it is sinfully rich and so delicious! Nana Betty
