How to Make One Egg Chocolate Cake

Preheat oven to 190°C (375°F). Grease and flour a 20cm round cake tin, lining the base with baking paper.
In a small saucepan, melt 50g butter and 60ml golden syrup over low heat.
Pour the melted butter and syrup into a medium bowl.
Add 1 large egg and 100g caster sugar. Beat well using a hand mixer or whisk until light and fluffy.
In a separate bowl, sift together 40g unsweetened cocoa powder, 60g plain flour, and 1 teaspoon baking powder.
Gently fold the dry ingredients into the wet ingredients until just combined. Do not overmix.
In a small bowl, dissolve 1/2 teaspoon baking soda in 2 tablespoons of milk.
Gently fold the dissolved baking soda mixture into the batter.
Pour the batter into the prepared tin and bake for 30-35 minutes, or until a skewer inserted into the center comes out clean.
Let the cake cool in the tin for 5 minutes before turning it out onto a wire rack to cool completely.
Once completely cool, frost with chocolate icing (recipe below).
**Chocolate Icing:** Sift together 150g icing sugar and 20g unsweetened cocoa powder in a bowl. Add 50g softened butter and gradually add water, mixing until you reach a spreadable consistency. Add vanilla extract to taste.
