Equipment

  • Large Cookie Scoop with Release Lever (2 1/2 - 3 tbsp capacity)

Ingredients
 

  • ½ cup unsalted butter, melted
  • ¾ cup creamy peanut butter
  • 1 cup granulated sugar
  • 1 tsp vanilla extract
  • 1 large egg
  • 1 large egg yolk (save the extra white for another use)
  • 2 cups all-purpose flour, fluffed, spooned and leveled
  • ½ tsp baking soda
  • ½ tsp coarse Kosher salt (if using table salt, use half the amount)
  • 1 tsp ground cinnamon

Instructions
 

  • In a saucepan, melt the butter over medium heat, then remove from the heat. In a bowl, whisk together the hot melted butter with the peanut butter until smooth.
  • Whisk in the sugar and the vanilla extract, then whisk in the egg and egg yolk until well combined.
  • Separately, whisk together the flour, baking soda, salt, and cinnamon. Add the dry ingredients to the wet ingredients, and stir the dough until all the flour is incorporated.
  • Cover the bowl with plastic wrap and refrigerate for 1 1/2 hours.
  • Preheat the oven to 350 F, and position a rack in the center of the oven. Line a rimmed baking sheet with parchment paper.
  • Use a large cookie scoop (2 1/2 - 3 tbsp capacity) to scoop 16 balls of dough. The dough may be a bit crumbly; just press it into the cookie scoop. Use the tines of a fork to slightly flatten each dough ball in a classic criss-cross pattern.
  • Place the dough balls 3 inches apart on the baking sheet and bake on the center oven rack for about 16 minutes.
  • Cool the cookies for 5 minutes on the baking sheet, then transfer them to a cooling rack to cool completely. If you like, lightly sprinkle the tops of the cookies with cinnamon sugar and flaky salt.

Notes

  • Store leftover cookies in an airtight container at room temperature for up to 3-5 days, or frozen for 3-6 months.
  • Peanut butter that's not labeled "all-natural" is usually best for baking, as it's more stable.  If using a drippy all-natural peanut butter (which contains only peanuts and salt, with no other oils), you should increase the flour by a couple of tablespoons to keep the cookies from spreading too much.
