In a large mixing bowl, whisk together room temperature eggs and granulated sugar until frothy, about 3-5 minutes. Gradually mix in vegetable oil, milk, and vanilla extract.

Sift the plain flour and baking powder together, then gently fold into the wet ingredients until just combined.

Divide the dough into two equal portions, tint one half yellow and the other half red using gel food coloring.

Preheat your oven to 350°F (180°C). Roll tablespoon-sized portions of dough into balls and arrange them on a lined baking sheet.

Bake for 12-15 minutes, until bottoms are lightly golden and tops remain soft. Do not over-bake.

Roll baked cookies in granulated sugar immediately after removing from the oven. Optionally brush with warm sugar syrup and garnish with mint leaves.
