Preheat the oven to 350 degrees and line two cookie sheets with parchment paper
Using a standing mixer, beat the butter, sugar, eggs, and vanilla until combined and fluffy
Using a medium bowl, whisk the flour, and baking powder. Gradually beat the flour into the wet ingredients until a dough forms
Fold in the 1½ cups crushed whopper eggs into the dough
Using a medium scooper, scoop dough into your hands and roll it into a ball. To make even round cookies, using a food scale, weigh each dough ball to 2.5oz
Press the dough balls onto a cookie sheet and lightly press them into a thick disk
Bake in the oven for 12-15 minutes or until lightly brown. Remove and allow to cool completely
