You will need: 1 cup (240 ml) caster sugar, 1 tablespoon (15 g) vanilla extract, 2 tablespoons (14 oz) butter, and 2 teaspoons (1 tsp) lemon extract. Measure out the dry ingredients and add to the wet ingredients until they are well combined. Add the egg yolks and mix until the mixture is light and fluffy. Pour the batter into the prepared pan and bake in the oven for 20 to 25 minutes or until golden brown. Allow the cakes to cool before removing them from the pan.
