For the Frosting:

  • 100-125 ml evaporated milk
  • 1 tsp orange extract

How to Make Chocolate Orange Traybake Cake

  1. Preheat and Prepare: Preheat your oven to 160°C/140°C Fan and line a 9×13″ tin with parchment paper.
  2. Melt Chocolate and Butter: In a heatproof bowl, microwave the dark chocolate and butter until melted; this usually takes about two minutes.
  3. Prepare Coffee Mixture: Mix the instant coffee granules with 125ml of boiling water, then add the coffee mixture to the melted chocolate and butter. Stir well until smooth!
  4. Combine Dry Ingredients: In a separate large bowl, combine the plain flour, cocoa powder, baking powder, bicarbonate of soda, caster sugar, and light brown sugar. Mix thoroughly.
  5. Prepare Wet Ingredients: Mix the eggs with the buttermilk and orange extract. Add the chocolate mixture and the egg mix to the dry ingredients, stirring together gently. Avoid overmixing; just use a bowl and spatula, no need for an electric mixer.
  6. Bake: Pour the cake batter into the prepared tin and bake in the oven for 50-60 minutes (may take slightly longer in some ovens). Once baked, leave the cake to cool in the tin or remove after 10-15 minutes and cool on a wire rack for a softer cake.

How to Make Orange Frosting

  1. Beat Butter: With an electric mixer and paddle attachment, beat the unsalted butter until smooth and supple, which takes a couple of minutes.
  2. Add Dry Ingredients and Milk: Gradually add the icing sugar and cocoa powder alternatively with the evaporated milk until fully incorporated. Mix in the orange extract, and continue to beat for a couple of minutes until the frosting is smooth and creamy. The amount of evaporated milk can be adjusted to achieve your desired consistency.

  1. Can I use milk chocolate instead of dark chocolate for the cake?

    While dark chocolate adds a rich flavor, you can use milk chocolate if you prefer a sweeter taste. Adjust the sugar quantity accordingly.

  2. Is it necessary to use instant coffee in the recipe?

    Instant coffee enhances the chocolate flavor, but you can omit it if you’re not a coffee fan. The cake will still be delicious.

  3. Can I make the frosting in advance?

    Absolutely! You can prepare the frosting ahead of time and store it in the refrigerator. Just ensure it’s at room temperature before frosting the cake.

  4. What can I use instead of buttermilk?

    If you don’t have buttermilk, you can make a substitute by adding 1 tablespoon of lemon juice or white vinegar to 1 cup of milk. Let it sit for 5 minutes before using.

  5. How should I store leftover cake?

    Store any leftover cake in an airtight container at room temperature for up to 2 days, or in the refrigerator for longer freshness.
