This cake tastes, unsurprisingly, just like a Terry’s Chocolate Orange. I don’t use orange flavoured chocolate for the chocolate chips (as I like eating it too much) but you could easily do this.
First gently melt 250g unsalted butter and add 300g caster sugar.
Stir until well mixed then cool slightly.
Add 3 large eggs (I used 4 very small ones) and mix again and a teaspoon of orange extract.
Add 200g self-raising flour and 50g cocoa and mix.
Finally add 100g chocolate chips – I used a dark chocolate bar chopped up and mix again.
Tip the mixture into a greased, lined baking tin – mine was 20cm x 30cm.
Bake at 160C for aboout 30 minutes until springy to the touch and a skewer comes out clean when poked into the centre.
Turn out onto a wire rack to cool.
You can double the icing recipe and freeze half for next time – if you do this you use a whole tin of condensed milk rather than leaving half a tin in the fridge. The ingredients listed here are for 1 portion.
Whilst the cake is cooling make the icing. Melt together 85g butter with 85g sugar.
To this add 200g condensed milk and bring to the boil over a very gentle heat stirring all the time.
As soon as it has come to the boil turn off the heat and keep stirring until it stops bubbling. Leave to cool for 5 minutes then add 50g dark chocolate and a teaspoon of orange extract.
Stir together until well blended then leave to cool until the icing is thick enough to spread on the cake.
Spread the icing on the cake and leave to cool fully. My icing is a little lumpy as I let it cool too much before spreading.
Cut into squares, eat and enjoy!
