Make the vanilla dough

• Mix in the egg yolk, then stir in the self-raising flour until a soft dough forms.

Make the chocolate dough

• Divide the dough in half.
• Knead the cacao powder and the remaining maple syrup into one half until evenly dark.

Swirl the doughs

• Pinch off pieces of both doughs and press them together loosely to create a marbled effect.
• Shape into small balls and place them on a lined baking tray, leaving space between them.

Bake the cookies
