Ingredients

Chocolate Cookies

  • 113 grams salted butter, melted
  • 300 grams light brown sugar, lightly packed
  • 2 large eggs, room temperature
  • 180 grams all purpose flour, spooned and leveled
  • 52 grams unsweetened cocoa powder, spooned and leveled
  • 2 tsp baking powder
  • 1/2 tsp fine sea salt
  • 4 oz peanut butter cups, roughly chopped

Peanut Butter Frosting

  • 264 grams (1 cup) creamy peanut butter
  • 56 grams salted butter, softened
  • 1 tsp vanilla extract
  • 120 grams powdered sugar, spooned and leveled

Chocolate Ganache

  • 113 grams dark chocolate chips
  • 120 mL heavy whipping cream

Method

Chocolate Cookies

  1. Preheat the oven to 350F/177C convection (325F/163C conventional) and line a large cookie sheet.
  2. In a medium bowl, combine the melted butter with the brown sugar and egg. Whisk aggressively, for 2-3 minutes, until it lightens in color.
    113 grams salted butter melted, 300 grams light brown sugar lightly packed, 2 large eggs room temperature
  3. Add the flour, cocoa powder, baking powder and salt and use a rubber spatula to fold the dough just until the flour is almost combined.
    180 grams all purpose flour spooned and leveled, 52 grams unsweetened cocoa powder spooned and leveled, 2 tsp baking powder, 1/2 tsp fine sea salt
  4. Add the chopped chocolate and fold until all the flour is combined and the chocolate is evenly distributed.
    4 oz peanut butter cups roughly chopped
  5. Scoop the dough into 14 round balls with a 2 ounce cookie scoop. Roll them so they're smooth and then place five per pan. 
  6. Bake for about 6 minutes then remove the pan from the oven and bang it on the counter a few times so the cookies flatten a little. Quickly use a biscuit cutter (or anything round) to scoot the cookies back into a round shape and finish baking for another 6 minutes. Then bang them on the counter and scoot them with the biscuit cutter again. Allow them to cool to room temperature

Chocolate Ganache

  1. Place the chocolate chips in a small bowl and set aside.
    113 grams dark chocolate chips
  2. Place the cream in a small pot over medium-low heat and gently heat hit until it's simmering.
    120 mL heavy whipping cream
  3. Pour the hot cream over the chocolate chips and cover with a lid or towel. Let it rest for a few minutes and then mix until it’s smooth.
  4. Allow the ganache to cool for 10-20 minutes while you make the peanut butter frosting.

Peanut Butter Frosting

  1. Place the peanut butter and butter in a small or medium pot over medium-low heat and whisk until they're completely melted and combined.
    264 grams (1 cup) creamy peanut butter, 56 grams salted butter softened
  2. Add the vanilla and powdered sugar and whisk it together until it's completely smooth.
    1 tsp vanilla extract, 120 grams powdered sugar spooned and leveled
  3. Spread on top of the cookies. I had just enough for the 14 cookies.
  4. I like to freeze the cookies with the peanut butter frosting for a few minutes before topping with the chocolate ganache. It's not essential but it helps the chocolate set quicker without running off the edge.
  5. Spoon the cooled-but-still-runny chocolate ganache on top of the chilled peanut butter frosting and top with some sea salt flakes and some peanut butter cup chunks.
