Melt ¾ cup of butter in a saucepan over medium heat. Stir frequently until the butter foams, turns golden with brown bits at the bottom, and smells nutty (approximately 5–8 minutes). Remove from heat and let it cool slightly.

In a large bowl, whisk together the cooled browned butter, softened butter, brown sugar, white sugar, eggs, and vanilla extract. Mix by hand for about one minute until smooth and glossy. Alternatively, a hand mixer can be used.

In a separate bowl, whisk together all-purpose flour, cake or pastry flour, baking soda, baking powder, and cornstarch. Gradually mix the dry ingredients into the wet ingredients using a wooden spoon, transitioning to hand-kneading if needed for better dough consistency.
04 -
Add semi-sweet chocolate chips, crushed Mini Eggs, and white chocolate chips (if using). Mix until the ingredients are evenly incorporated.

Form the dough into a log or tube shape. Wrap tightly in plastic wrap and chill in the refrigerator overnight or for a minimum of one hour.
06 -
Remove the dough from the fridge 30 minutes prior to baking. Preheat the oven to 175°C (350°F) and line a baking sheet with parchment paper.
07 -
Roll the dough into balls and arrange them on the baking sheet. Bake for 12 minutes, or until the edges are set and the centers appear slightly soft.
