For those that wanna try it out without having to beat the whole game again to get the ingredients/ flip through a bunch of screenshots.

Ingredients:
3 eggs
200 grams of butter (about 1 stick and 3/4ths of another)
1 cup sugar
1 tsp vanilla essence
1/2 cup milk
2 cups flour
2 tsp baking powder
2 tbsp golden syrup
1 tsp cocoa
1 tsp cinnamon
1 tsp nutmeg
(Note nutmeg isn’t listed in the ingredients credits but it’s used later so I’m just guesstimating here)

Preheat your Oven to 160C (320F)

Grease and line a 23 cm round tin with baking paper

Cream butter and sugar.
(Note: creaming is the process of incorporating sugar and softened butter together into a uniform, fluffy, and smooth texture. Make sure the sugar is dissolved and evenly dispersed.

Add the eggs one at a time, then the vanilla and milk, and mix to combine.

Add flower and baking powder and mix to combine.

Spoon half of the mixture into the prepared tin.

Mix golden syrup, cocoa, cinnamon, and nutmeg into remaining mixture

Pour this over the top of mixture in tin.

Using a knife, cut through combined mixtures several times to create marbled effect.

Bake for 50-60 minutes.

Decorate and Enjoy
