In a large mixing bowl, combine self-raising flour with vegan margarine. Rub the margarine into the flour until the mixture resembles fine crumbs.

Stir in caster sugar until evenly distributed.

In a separate cup, mix together vanilla extract, lemon extract, and soy milk. Add to the dry ingredients along with lime green food coloring, stirring until a dough forms.

Mix until a cohesive dough forms, adjusting with soy milk or flour if needed.

Wrap the dough in plastic wrap and chill in the refrigerator for 30 minutes.

Preheat your oven to 180°C (350°F) and line a baking tray with parchment paper.

Once chilled, divide the dough into 12 equal portions, roll each into a ball, and coat in icing sugar.

Lightly flatten each dough ball before placing them on the baking tray.

Bake the cookies for 10-12 minutes, until edges are firm and centers are no longer wet.

Press a red Skittle into the center of each cookie immediately after baking.

Allow to cool on the baking tray for a few minutes before transferring to a wire rack to cool completely.
