In the bowl of a stand mixer, add the butter, granulated sugar, and brown sugar. Beat on medium speed, just until combined.
1 cup unsalted butter, 1 cup granulated sugar, 3/4 cup brown sugar
Add the eggs, one at a time. Be on medium-high speed, be sure to beat well in-between, scraping the sides. You want to beat for a good 2-3 minutes to make sure it gets light and creamy.
2 extra large eggs
Add peanut butter and vanilla extract. Beat until combined.
3/4 cup creamy peanut butter, 2 teaspoons vanilla extract
Sift the dry ingredients into a bowl. Add half the mixture to the bowl of wet ingredients, and mix on low speed just until combined. Add the rest of the dry ingredients, and mix on low speed again. Be careful not to overmix!
2 3/4 cups all-purpose flour, 1/2 teaspoon baking soda, 3/4 teaspoon sea salt
Fold in the chocolate chunks/chips.
2 cups dark chocolate chunks or chips
Portion the dough into balls, using a 1/4 cup scoop. Arrange them on a baking sheet, and transfer to the fridge overnight. Please do not skip this step!
Bake at 350 degrees Fahrenheit for 13-15 minutes. Let cool on the baking sheet for 3-4 minutes. Then, transfer to a wire rack to cool completely.
