Preheat the oven to 350-degrees Fahrenheit.

If you're using the Cadbury mini eggs with a hard candy shell (or other candy), put them into a large zip-top bag. Use a rolling pin or spoon to crush the candy into pieces around the size of chocolate chips. (Some bigger pieces are fine if that's what you like.)

Cream the butter and sugar together in a mixing bowl or with your stand mixer until it is light and fluffy. (It took mine about 2-3 minutes total.)

Add in the eggs one at a time and mix well after each.

Add in the vanilla and mix well.

In a separate bowl, mix together the flour, salt, baking soda and baking powder. Stir until combined.

Gradually add the dry mixture into the wet mixture and stir until incorporated.

Add the white chocolate chips, milk chocolate chips and prepared candy.

Roll the dough into 1-inch balls or use a cookie scoop. Place the dough balls onto a cookie sheet. (I cover mine with parchment paper for easier clean up.)

Bake at 350-degrees for about 10 minutes until the edges are lightly browned. Remove from the oven and let them cool for about 1 minute on the cookie sheet before removing them to a wire rack to cool.

Once cooled, store them in an air-tight container or zip-top bag.
