Preheat Oven: Preheat your oven to 350°F (175°C). Line baking sheets with parchment paper or silicone baking mats.
Cream Butter and Sugars: In a large mixing bowl, cream together the softened butter, granulated sugar, and brown sugar until light and fluffy.
Add Eggs and Vanilla: Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next. Stir in the vanilla extract.
Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, baking powder, and salt.
Mix Wet and Dry Ingredients: Gradually add the dry ingredients to the wet mixture, mixing until just combined.
Fold in Chocolate: Gently fold in the chopped mini chocolate eggs and semi-sweet chocolate chips until evenly distributed.
Scoop Dough: Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheets, spacing them about 2 inches apart.
Bake: Bake in the preheated oven for 10-12 minutes, or until the edges are lightly golden. The centers may appear slightly underbaked.
Cool: Allow the cookies to cool on the baking sheets for 5 minutes before transferring them to wire racks to cool completely.
