Equipment

Ingredients
 
 

  • ½ cup unsalted butter
  • ¾ cup fresh mint, firmly packed and roughly chopped
  • ½ cup dark brown sugar, firmly packed
  • ½ cup granulated sugar
  • 1 large egg, at room temperature
  • 2 teaspoons pure vanilla extract
  • 1¼ cups all-purpose flour
  • ⅓ cup cocoa powder
  • 1 teaspoon baking soda
  • ½ teaspoon kosher salt
  • ½ cup chocolate chunks, plus extra to press into top of the dough before baking

Instructions
 

  • Make the dough: Place the butter and mint in a small saucepan over medium heat. Melt the butter, swirling occasionally. After about 2 to 3 minutes, when you can smell the mint, remove from heat and let the butter continue to steep for 30 minutes.
  • Strain the butter through a fine mesh sieve into a medium bowl, pressing the leaves to extract all of the butter from the leaves. Allow butter to cool to a semi-soft texture (it will help the creaming process if the butter isn’t too hard or still liquid).
  • Add the sugars to the butter and beat with a hand mixer until everything is light and creamy, about 3 to 5 minutes. Add the egg and vanilla extract and beat for an additional minute.
  • In a small bowl, sift the flour and cocoa powder together to remove any lumps, then whisk in the baking soda and salt.
  • Add the dry ingredients to the butter mixture and beat a low speed until just combined, stopping to scrape the bowl as necessary. Fold in the chocolate chunks.
  • Remove the cookie dough from the bowl, wrap in plastic wrap, and press flat into a disk. Chill for at least 1 hour (or up to 3 days)
  • To make cookies: Preheat the oven to 350°F.
  • Line two half-sheet baking pans with a Silpat silicone mat or parchment paper.
  • Divide the dough into 12 equal portions (I use a small cookie scoop), rolling into 12 balls. Space six balls on each cookie sheet (the cookies can spread considerably). Press a few extra reserved chocolate chunks in the top of each cookie.
  • Bake for 11 to 12 minutes for cookies, rotating the pans half-way through.
  • Let cool on the baking sheet for 2 minutes, and then use a large spatula to move to a cooling rack and cool completely.
  • To make bars: Preheat oven to 325°F.
  • Line a 9- x 13-inch baking pan with parchment paper, leaving an overhang to assist lifting.
  • Press the dough into the prepared baking pan as evenly as possible (use plastic wrap on the dough and a small pie roller if possible). Press some extra chocolate chunks in the top of the dough.
  • Bake bars for 25 to 30 minutes. Allow to cool in the pan for 15 minutes, then use the parchment paper overhang to lift bars onto a cooling rack to cool completely.
  • Cut into 48 approximately 1- x 2-inch bars.

Notes

If you don’t want to deal with infusing butter with mint (although it’s so simple!), you can substitute ½ teaspoon peppermint extract, adding with the vanilla.
For the pictures, I made one batch of dough to bake half as cookies and half as bars, so I used one baking sheet and a 9- x 9-inch baking pan. These bars baked for 20 minutes.
