Double Chocolate Cake with Old Fashion Chocolate Fudge Frosting

Dive into this dark, dense, rich, and moist Double Chocolate Cake that is covered with creamy smooth Old Fashion Chocolate Fudge Frosting. The first bite will take you back to when the simple things in life made you grin from ear to ear. This “show-stopping” decadent dessert is for any day of the week. You don’t need a special occasion to treat your friends, family, or yourself to a big slice of Double Chocolate Cake and a big glass of ice-cold milk.

The inspiration for this recipe comes from Aunt Irene’s “Red Devil’s Food Cake” with frosting (page 80)  by way of Aunt Carol Jean’s “My Cookbook” a collection of family recipes handed down through the years. Aunt Carol Jean lovingly gathered and put together a cookbook of old family recipes from handwritten scraps of paper, backs of envelopes, note cards, and thorough note-taking over the phone.

I love finding older recipes that use ingredients that are commonly found in the traditional larders of the past. Ingredients like butter, all-purpose flour, Hershey’s Cocoa Powder, sour milk (buttermilk), eggs, baking soda, and granulated sugar. These ingredients were economical to purchase in bulk and they would keep for an extended period of time. No need to purchase special ingredients like Cake Flour or Powder Sugar. Because people kept these ingredients on hand they could quickly be combined in one bowl or saucepan to create a delicious treat for dessert, unexpected guest, or for that special occasion.

“Everyone looked forward to my dad’s oldest sister’s “baked goods.” Aunt Irene was famous at church bake sales for her Peanut Squares. For her nieces and nephew, she baked Cowboy Cookies. And for family reunions, she baked her “show-stopping” Red Devil’s Food Cake. ~ Aunt Carol Jean Knight

It was the simplicity of the recipe for the Red Devil’s Food Cake and the frosting that intrigued me. I could tell by reading the cake recipe it would not be extremely sweet. The recipe called for blending the natural cocoa powder (Hershey’s Cocoa Powder) and baking soda with warm water. This reduces the acidic nature of the cocoa powder, tames the flavor of the baking soda, and also releases the excess CO2 from the cocoa powder before being blended with the other ingredient and baked.

The recipe and cooking process for the Chocolate Fudge Frosting is really special. It is an Old Fashion Cooked Frosting which uses Granulated Sugar rather than Icing Sugar/Powder Sugar to sweeten it. The end result is a frosting that is thick, smooth, and creamy in texture. A cross between dense chocolate pudding and fudge. I don’t know why this style of frosting fell out of favor for powdered sugar frostings, but I’m here to say this type of frosting is much better.

Playing with my food: I made the recipes as they were written by Aunt Irene and it produced a really delicious cake and creamy frosting but I wanted more chocolate flavor in both recipes. Through multiple test batches, I found the keys to the best flavor and texture for each recipe. For the cake batter, I added more cocoa powder, increased the butter and buttermilk, decreased the flour, and added 5 oz. (141 g.) finely chopped 70% chocolate making it a Double Chocolate Cake. The cooked frosting saw an increase of ingredients across the board for added flavor with the extra addition of cocoa powder and an increase of butter from 2 Tablespoons to 1-½ cups for creaminess and richness and finally, the addition of sea salt to balance the sweetness and to bring out the chocolate flavor.

The simplicity of Mixing: The Double Chocolate Cake recipe is designed to be mixed by hand in one bowl, but an electric hand mixer can be used if so desired. Mix on low speed to first incorporate the ingredients and then on medium-high to beat well. The Chocolate Fudge Frosting is mixed, cooked, and cooled in one saucepan. The butter is added in 4 additions to the warm cooked frosting and then beaten in until smooth. Whisking after the last addition of butter makes for a smooth and glossy frosting. Once cooled completely the Chocolate Fudge Frosting becomes very thick and dark. The frosting is beaten one last time before being slathered all over the cake layers.

As with all baking recipes I recommend you weigh the ingredients for the Double Chocolate Cake and Old Fashion Chocolate Fudge Frosting. Weighing ensures you have a consistent recipe each and every time. As a baker, we are always striving to remove any variables from the process of baking.

    I would love to make this recipe but your measurements are off. Please advise if you made the recipe using the weight measurements you list or the volume measurements you list. For example… 6 Tablespoons of flour do not weigh 60 grams they weigh 37 grams.
