INGREDIENT NOTES
These are some of the key ingredients for this recipe. For a full list of ingredients, check out the recipe card below.
- Eggs: Take them out of the fridge 1-2 hours before baking (depending how warm your kitchen is).
- Buttermilk: Buttermilk makes for a softer and more tender cake. Measure out the buttermilk and let it come to room temperature 1-2 hours before baking (depending how warm your kitchen is).
- Boiled water: Heat up a kettle of water before you start. Add the boiled water to a measuring cup and while you prepare the rest of the ingredients, let it cool down a bit, so it's not piping hot.
- Cocoa powder: I use high quality dutch processed cocoa powder for the best flavor, my favorite is from Valrhona.
- Instant espresso powder: I use Nescafe Gold espresso powder as it dissolves quickly and as a great flavor as it's 100% arabica coffee
- Orange juice: Use freshly squeezed orange juice or store bought orange juice without pulp.
- Milk chocolate: I recommend using a high quality milk chocolate to get the best flavor, from brands like Callebaut, Valrhona or Ghiradelli.
STEP BY STEP INSTRUCTIONS - CHOCOLATE CAKE LAYERS
Here is how make and bake these chocolate orange cake. This recipe doesn't need an electric mixer. Just three large bowls, a whisk and a spatula.

STEP 2: In a bowl sift all of dry ingredients together. Give it a stir to make sure everything has be combined.
STEP 3: In another mixing bowl add all of the wet ingredients and with a hand whisk, whisk them together until combined. Be sure to not mix the ingredients too vigorously so the eggs don’t get over mixed.

STEP BY STEP INSTRUCTIONS - GANACHE AND ASSEMBLING
STEP 1: In a small saucepan, over medium heat, add the heavy cream and let it heat up until it starts to bubble. Pour the cream over the milk chocolate chips and stir it together with a rubber spatula until smooth and combined. Then add the orange juice and stir until combined.
STEP 2: Place a piece of cling film on top of the ganache so it touches the surface of the ganache, to not create a crust, and place it in the fridge for 1 and 45 to 2 hours. The ganache should be firm but spreadable when ready.
STEP 3: To assemble it, place the first sponge layer to your serving dish or cake board on your turntable. If you don’t have a turntable, don’t worry, you can easily decorate the cake without it.
STEP 4: Brush orange juice on the chocolate cake layers to add some extra orange flavor.

Add the remaining milk chocolate ganache and cover the cake in an even layer. The cake doesn’t have to look perfect, just have fun and enjoy being creative!
EXPERT BAKING TIPS
- Use a kitchen scale: My default setting for my recipes is grams as it is the most precise way of measuring out your ingredients, I therefore highly recommend using a kitchen scale.
- Don't over mix your batter: I always use a spatula, after everything has mixed together, and give it one final gently fold together, to make sure everything in the bottom of the mixing bowl has been mixed into the batter.
- Light vs. dark baking pans: For the best result, use an aluminum baking pan, greased with butter and lined with baking paper in the bottom. Aluminum pan are light in color and therefore attracts less heat which means they bake more gently which results in a softer cake. If you use a e.g. a black baking pan it'll attract a lot more heat, which will then give a darker crust, that results in a dryer cake.

FAQ
Yes, then just remove 2 tablespoon of the water and replace it with 2 tablespoon of orange juice.
Yes, this cake keeps moist at room temperature. Just cover the cake with a lid or in an airtight container. Enjoy the cake within 2-3 days.
I recommend using a cake tester. Once the time has passed, per the recipe, insert the cake tester in the middle of the cake and once it comes out clean, with no cake batter on it, then it's done.
