Preheat your oven to 350°F (180°C). Cream together butter, granulated sugar, and light brown sugar until pale and fluffy.

Incorporate eggs one at a time, followed by the vanilla extract until smooth.

Sift together flour, baking soda, and fine salt. Gradually mix into wet ingredients until just combined.

Fold in finely chopped Cadbury Mini Eggs and dark chocolate chunks evenly.

Shape dough into balls, chill for at least 1 hour or freeze for 30 minutes to prevent excessive spreading.

Bake in preheated oven for 12-15 minutes, adding coarsely chopped Mini Eggs at 9 minutes. Cookies are done when edges are golden.

Let cookies cool on the baking sheet for 10 minutes before transferring to a wire rack.
