Eric's Favorite (Chocolate and Peanut Butter Marble Cookies)

These cookies have it all - brown butter, a dark chocolate side, a peanut butter side and oh, not to mention, they are HUGE. They taste like a brownie and a peanut butter cookie rolled in one. Soft in the middle, chew edges. There's a reason they are Eric's favorite.

Ingredients

  • 226 grams/1 cup butter

For the brownie cookie:

  • 118 grams brown sugar 1/2 cup 2 tablespoons, spooned and packed
  • 1 tablespoon milk of choice
  • 1 large egg at room temperature
  • 50 grams white sugar 1/4 cup
  • 175 grams flour 1 1/3 cup
  • 2 tablespoons dutch process cocoa
  • 1 1/2 teaspoons baking powder
  • 1/4 teaspoon salt

For the peanut butter cookie:

  • 1 tablespoons milk of choice
  • 118 grams brown sugar 1/2 cup 2 tablespoons, spooned and packed,
  • 1 large egg at room temperature
  • 75 grams creamy peanut butter 1/3 cup
  • 50 grams white sugar 1/4 cup
  • 183 grams flour 1 1/3 cup and 1 tablespoon
  • 1 1/2 teaspoon baking powder
  • 1/4 teaspoon salt

For both:

  • 113 grams 70% cocoa chocolate chopped

Instructions

  • Add the 1 cup of butter (2 sticks) to a saucepan. Put the saucepan on low heat and melt the butter fully. Raise the heat to medium and stir constantly. Let the butter foam slightly. When it turns a rich brown color remove it from the heat and whisk until the butter turns dark brown.
  • Divide the butter evenly into two large bowls. Since moisture has cooked off during the browning process, each bowl should contain about 100 grams of butter.
  • Add 1 tablespoon of milk to each bowl and whisk to temper the butter. Let it cool for a few more minutes.
  • Whisk one egg into each bowl. Then add the sugars and whisk again.
  • For the chocolate batter, add in the flour, cocoa powder, baking powder and salt to one bowl. Stir to combine.
  • For the peanut butter, whisk in the peanut butter to the second bowl, then add the flour, baking powder and salt. Stir to combine.
  • Split the chocolate chips evenly between the cookies.
  • Scoop out 3 tablespoons of the dough. Roll the dough together to create 10 large "marble" balls.
  • Place the cookie dough balls on a parchment-lined baking sheet and chill in the refrigerator while you preheat the oven to 350°F.
  • Bake for 10-12 minutes at 350°F. The key is to remove the cookies before they look fully done. They will continue to "cook" outside of the oven, so this method helps them maintain the chewy texture.
  • Let cool and serve!
