In a mixer or a large bowl, mix melted butter and sugars.
Add egg and vanilla extract. Mix until smooth and well combined.
To the same bowl, add flour, baking soda, and salt. Mix until just combined. Do NOT over mix!
Fold in chocolate chunks and Eggies.
Using a cookie scoop, form dough into balls (approx. 1.5 tablespoons of dough).
Place on a baking sheet and refrigerate the dough balls for, at least, 20 minutes (the longer, the better). You can freeze any leftover dough for future use.*
Preheat oven to 350°F.
When ready to bake, remove dough from fridge and place on a light coloured pan that has been lined in parchment.
Bake for 10-11 minutes until the edges are golden brown.
Remove from oven and cool for 5 minutes.
Serve and enjoy!
