In a small bowl, whisk together your butter, coconut milk, vanilla extract, and egg. Fold your wet ingredients into your dry mixture and mix with a rubber spatula until all ingredients are combined and a dough ball forms.
Place your dough onto your lined baking sheet and press it into a disk shape that is about 1 inch thick. Cut into 8 wedges and move your wedges about 1 inch apart and bake for 18-22 minutes. Leave for at least 10-15 minutes to cool on the baking sheet before moving to your cooling rack and enjoy like that or add the optional topping.
