Instructions

For the Chocolate Layer Cake

Preheat the oven to 350 degrees Fahrenheit. Grease two 8 inch cake pans with vegetable oil, line with parchment paper and then lightly grease again with vegetable oil.
In a large bowl whisk together the 3 cups gluten free flour, ½ cup cocoa powder, 2 cups granulated sugar, 2 teaspoons baking soda and 2 teaspoons kosher salt.
Using clean hands, make 3 wells in the dry ingredients for the wet ingredients to be poured into.
In one well pour the ¾ cup plus 2 tablespoons vegetable oil, in the other well pour the 2 tablespoons white vinegar and in the last, pour the 2 teaspoons pure vanilla extract.
Pour the 2 cups cold water on top of all the ingredients.
Use a whisk to mix everything together until fully combined. If it gets too thick for the whisk, switch to using a spatula. Do not over-mix.
Using a spatula, scoop the batter into a greased and parchment lined 8 inch cake pan and smooth the top with a butter knife.
Bake the cakes in the center rack at 350 degrees Fahrenheit for 45 minutes until the top is slightly springy when carefully touched.
Let the cakes cool almost completely in the pan for 15 mins before trying to remove. Then remove from pans and let cool completely on a wire cooling rack.
Once cool, slice both cakes in half horizontally. Now you have 4 thin layers of cake.
If your cakes have dome tops, you can take a thin layer off the tops of the cake with a knife, to make a flat surface.

For the Chocolate Fudge Frosting

In the large bowl of an electric mixer or using a hand held mixer, beat the 1 ½ cups unsalted butter until smooth.
Slowly add in the 7 cups plus confectioners' sugar, the 2 cups cocoa powder and the 4 teaspoons pure vanilla extract and beat until combined.
Add in the 1 cup of room temperature water...a little at a time until you get the desired consistency.
You may not need to use all the water.
Divide frosting into 5 equal servings.

Assemble the Cake

Place one layer of cake on a cake plate/stand. Scoop ⅕ (about 1 cup) of frosting on top of the layer and use an icing spatula to spread it around.
Place another layer of cake on top; repeat this same process. Do this with 3 layers of cake.
Once you get to the last layer of cake, place it bottom (or flat) side up so the top of the cake is nice and flat. Use an icing spatula or a butter knife to frost the top and a thin layer on the sides of the cake.
You should only use a fifth of the frosting on the top and sides combined.
Pop the entire cake in the fridge uncovered for 15-20 minutes.

Make the Chocolate Ganache

Place the 6 ounces chocolate chips in a heat safe bowl. Set aside.
Pour the ½ cup heavy cream in a saucepan over medium heat, whisking constantly. Once it begins to simmer around the edges, immediately pour the cream over the chocolate chips.
Cover with plastic and let site one minute. Then remove plastic and whisk until smooth. Take the cake out of the fridge.
Immediately spoon all the liquid ganache on top of the cold cake.
Using an icing spatula, push the ganache around the edges of the cake so it drips down the sides.
Take the cake out of the fridge. Spoon almost all of the liquid ganache on top of the cake. Take an icing spatula and push the ganache around to the edges of the cake so it drips down the sides. Work quickly since the cold cake will harden the ganache fast.

Decorate the Cake

Put the rest of the fudge frosting into a piping bag and pipe a swirl all around the edge of the outside of the cake.
Place chocolate sprinkles on the fudge swirl if desired.
If you have frosting leftover, save it in a bowl covered in plastic wrap in the fridge for a few days.

Notes

Vegan: Use a dairy-free gluten free flour, vegan sugar, vegan baking sticks, vegan chocolate chips, vegan heavy cream and vegan sprinkles.

If you can't find a vegan heavy cream, check my section entitled "substitutions and variations" for how to make a vegan ganache with vegan baking sticks.

All Purpose Flour: I cannot test this due to celiac disease, but use 3 cups packed AP flour (504 grams), ½ cup packed cocoa powder (58 grams) and ¾ cup vegetable oil.

Storing: Once the cake is cut into, cut the entire cake into slices, wrap each slice in foil and store in a zip top bag in the fridge for up to 2 days.

When ready to eat, let the slices sit on the counter, in the foil for about an hour or until the cake is room temperature and soft. If desired, warm each slice in the microwave for 5-10 seconds; be careful not to burn your mouth.

Freezing: Wrap slices in foil, place in the zip top bag and freeze for up to 30 days.

When ready to eat, put the slices in the fridge the night before or leave them out on the counter for 2 hours prior to eating or until the cake is room temperature and soft. If desired, warm each slice in the microwave for 5-10 seconds; be careful not to burn your mouth.
