Preheat the oven to 375°F and line two 12x17-inch baking sheets with parchment paper and set aside.
In a large bowl, whisk together the 3¾ cups bread flour, 1 (3.3oz.) box instant vanilla pudding mix, 2 teaspoons baking powder, and 1¼ teaspoons salt. Set aside.
3¾ cups bread flour, 1 (3.3oz.) box instant vanilla pudding mix, 2 teaspoons baking powder, 1¼ teaspoons salt
In a separate large bowl or stand mixer fitted with a paddle attachment, cream together 1 cup unsalted butter and 1½ cups dark brown sugar for 1 minute until smooth.
1 cup unsalted butter, 1½ cups dark brown sugar
Add in the 3 large eggs one at a time, mixing after each one just until incorporated.
3 large eggs
Add 1½ teaspoons vanilla extract and mix for 2 minutes until light and fluffy, scraping down the sides of the bowl as needed.
1½ teaspoons vanilla extract
With the mixer running on low speed, slowly add the dry ingredients a little at a time to the wet ingredients until fully incorporated. The dough should come together in a play-doh texture and not be sticky.
Measure the dough into 2-ounce portions of dough. You can make these as drop cookies with a cookie scoop (we use a #24 size for these) or roll into balls.
Add ½ cup granulated sugar to a small bowl and roll the cookies in it to coat them.
Add 9 cookies to each pan with 2 inches of space between them. Bake one sheet at a time.
Bake for 7 to 9 minutes.
Remove from the oven and allow them to cool on the baking sheet for at least 5 minutes before transferring them to a wire rack to cool completely.
