Chocolate Orange Cake is rich, moist, and bursting with both chocolatey and orange flavor. It’s the perfect dessert to enjoy with a cup of afternoon tea!

Chocolate Orange Cake
The recipe is simple: I made a 2 layer sponge cake coated in rich chocolate buttercream and topped with Chocolate Orange slices.
I didn’t use fresh orange, just orange extract, which I found strong enough. To deepen the chocolate flavor, I added chocolate milk, cocoa powder, and milk chocolate chips, then finished with orange chocolate slices on top.

You'll Need
- All purpose flour: Measure your flour correctly! Spoon the mixture into the cup, measure and level with a knife.
- Baking Powder. It helps the batter rise, giving the cake a light texture.
- Caster Sugar. I like to use caster sugar, as it easily dissolves in the mixture.
- Milk Chocolate. Use dark chocolate if you want.
- Cocoa Powder. I recommend using a good quality cocoa powder for best results.
- Buttermilk. It helps create a cake that is light and soft.
- Eggs. I used 4 large eggs.
- Orange Extract. It adds just the right amount of citrus flavor to this cake.
- For the Chocolate Orange Buttercream: Use butter, Icing sugar and milk chocolate, cocoa powder and orange extract.
- For Topping: I used Terry's Chocolate Orange Slices.
