Ingredients
- Cocoa powder. This recipe uses dutch-processed cocoa, which can be found as Hershey's special dark cocoa in most grocery stores.
- Oranges. The zest of two large oranges will be used in the cake recipe.
- Orange extract. This extract is used in the milk chocolate ganache and should not be omitted.
- Heavy whipping cream. Used in both the milk chocolate and semi-sweet chocolate ganache.
- Buttermilk. For the chocolate orange cake. Sour cream or greek yogurt can be used in place of buttermilk.
- Coffee. This helps to moisten and bloom the cocoa powder and brings out the chocolate flavor. Hot water can be used in place of coffee.
- Chocolate. Both milk chocolate and semi-sweet chocolate (60-70% cacao) is used. Chocolate bars produce the best results.
- Terry's Chocolate Orange. To garnish the top of the cake. After all, this is a Terry's Chocolate Orange Cake!

Substitutions and Variations
- Natural cocoa can be used rather than dutch-processed cocoa. Note that the cake will be lighter in color, and will not have as deep of a chocolate flavor.
- Greek yogurt or sour cream can be used in place of buttermilk.
- Use dark chocolate in place of semi-sweet chocolate for the pourable ganache covering.
- Canola oil or sunflower oil (any neutral oil) can be used in place of vegetable oil.
- Peel an orange (with a vegetable peeler) and add the zest to the heavy cream that will go over the semi-sweet chocolate for extra orange flavor.
How to Make This Recipe
One: Whisk together the sugar and dry ingredients until no clumps remain.

Making Chocolate Ganache and Assembly
Seven: Mix together milk chocolate, hot heavy cream, and orange extract until smooth. Then cool until it becomes a spreadable consistency.
Eight: Use a serrated knife to cut the mounded top off of the cake. Then, slice the cake layers into three layers. Add almost half of the ganache to the top of the first layer, spreading fully to the edges.
Hot tip! Turn the cake on its side to cut the layers most evenly.
Nine: Add the second layer and repeat with ganache, then add the top layer. Use any leftover ganache to fill in any gaps on the sides of the cake.
Ten: Chop the semi-sweet chocolate, then pour over heavy whipping cream.
Hot tip! Slice off the sides of the cake to make completely even, clean sides. This will help with the most even coverage when pouring over the dark chocolate ganache.
Eleven: Stir carefully until the mixture becomes a silky smooth, thin chocolate mixture. Cool for a few minutes.
Twelve: Add the cake to a wire rack with a pan underneath, then very slowly pour the chocolate ganache over top, being sure to get equal coverage over all of the sides.
Hot tip! Keep the thin piece of parchment paper under the cake so you can easily transfer the cake to the serving platter. Then, slide the parchment out from underneath the cake.
To finish the cake, pipe the extra milk chocolate ganache on top of the cake, then add Terry's chocolate orange slices all over.
Expert Tips
- Use room temperature ingredients in the cake for best results. This includes eggs and buttermilk.
- Use strips of parchment paper (one on the length and one on the width) to line the loaf pan. This is necessary for clean removal from the pan and to move the cake around during the decorating process.
- Cool the cake completely before cutting to separate the layers.
- Cut very thin pieces off the sides of the cake after frosting so there are perfectly clean edges.
- Pour the ganache slowly over the cake, being sure to get coverage on every side and corner.
- Scrape the excess dark chocolate ganache off of the pan and store in the fridge. Re-melt and add to ice cream!

Chocolate ganache is a mix of heavy cream and chocolate, while chocolate frosting is typically a mix of butter, powdered sugar, and either cocoa powder or melted chocolate.
Chocolate ganache, once set, can be used as a frosting as is, or whipped to add air to make a fluffier version.

- Transfer it to the fridge or freezer and allow it to set, stirring every 5 minutes until thick, creamy, and spreadable. Then, allow it to sit at room temperature.
Assembly:
- Remove the mounded part on top of the cake until even. Slice the cake horizontally into 3 even layers using a serrated knife.
- Note: turn the loaf on its sides to make the cuts.
- Place a strip of parchment paper under the long side of the cake, leaving over hangs so you can transfer it later on.
- Add about ¾ cup of orange ganache and spread it evenly. Add the second cake layer, and repeat with the ganache. Add the top layer and gently press down.
- Use the ganache to fill any gaps in the sides and spread it evenly. If there are any very uneven sides, use a serrated knife to cut a clean edge.
- Use the parchment slings to transfer the cake to a wire rack. Add a sheet pan under the wire rack.
Chocolate Glaze
- Heat the heavy whipping cream and add it on top of the chopped dark chocolate. Allow it to stand for 1 minute, then mix until smooth. Allow it to cool for about 5 minutes, stirring occasionally to release heat. It will be a rather thin, pourable consistency.1 cup semi sweet chocolate, 1½ cups heavy whipping cream
- Pour the dark chocolate ganache slowly and evenly over the top and sides until it's completely coated.
- Allow it to sit for about 5 minutes, then use the parchment paper to carefully transfer the cake to a serving platter. Pull out the parchment paper strip to remove it.

Sara
Did you whip the orange filling ganache? In your photos yours looks a lot lighter and thicker than mine came out.
Callan Wenner
Hi Sara, I did not whip it! I just used a standard milk chocolate bar and let it cool completely until it was set up and became a super spreadable consistency!
Mo
Can I use G.F instead of cake flour?
Callan Wenner
Hi Mo, if you'd like to make this gluten free, I suggest using Bob's Red Mill 1-1 gluten free baking flour. I have used this product multiple times and it's a great equal substitution. I have not tested other products in depth, but know that one works.
Dee
flavour great. However, the filling never thickened to the point where it held any shape, wasn’t sure if the cream needed to be heated longer or if there is a difference between heavy whipping cream and whipping cream at 35%. I can’t get heavier cream so if the recipe specified the fat content, it would have made a difference in choosing this recipe over the others out there. Will be eating this in a bowl like a pudding.
Callan Wenner
Hi Dee, yes there is a difference in fat content between heavy whipping cream and heavy cream, which is why your ganache wouldn't have set up. In the U.S. it is differentiated by name (heavy, whipping, half and half, etc), but I will add a note on the percentage so this doesn't happen to anyone else.
