1cup(227g)salted butter, softened to room temperature
¾cup(159g)packed light brown sugar
¾cup(159g)granulated sugar
1teaspoonbaking soda
1teaspoonbaking powder
½teaspoonsalt
2large eggs
2teaspoonsvanilla extract
3cups(426g)all-purpose flour
9-ouncebag(255g)Cadbury eggs, lightly crushed (see note) to yield 1 1/3 cups crushed eggs (plus more for tops of cookies, if desired)
1cup(170g)chocolate chips
Instructions
Preheat the oven to 350 degrees F. Line baking sheets with parchment paper or lightly grease with cooking spray.
In a large bowl with a handheld electric mixer or in the bowl of an electric stand mixer fitted with the paddle attachment, add the butter, brown sugar, granulated sugar, baking soda, baking powder, and salt.
Cream together until light and fluffy, 1 to 2 minutes.
Add the eggs and vanilla and mix until well-combined.
Add the flour and mix until a few dry streaks remain.
Add the Cadbury eggs and chocolate chips and stir until evenly combined.
Scoop the dough about 2 tablespoons at a time (I use a #40 cookie scoop) and roll into balls. Place several inches apart on prepared baking sheets.
Optional: top cookie dough balls with several pieces of crushed Cadbury eggs.
Bake for 10 to 12 minutes (see note for cookies that flatten too much or stay too puffy).
Let the cookies rest on the baking sheets for 3-4 minutes before removing to a wire rack to cool completely.
Notes
Flour Amount: if you want a slightly thicker cookie OR your cookies often flatten in the oven, increase the flour to 3 1/4 cups (462 grams). Cadbury Eggs:The weight of the cadbury eggs (out of bag) will be right around 255 grams. To lightly crush the eggs, place the eggs in a quart or gallon ziploc bag, seal, and pound the eggs with a rolling pin.If you want to add extra crushed Cadbury eggs to the tops of the cookies before baking, plan for another 1/2 bag of Cadbury eggs. Flat/Puffy Cookies:If the cookies are flattening too much in the oven, increase the baking temperature to 375 degrees F (or next time, add 2 to 4 extra tablespoons of flour to the dough). If the cookies are staying too puffy in the oven, decrease the baking temperature to 325 degrees F (or next time, decrease flour by 2 to 4 tablespoons in the recipe).
