  • 8 tablespoons unsalted butter (114 grams)
  • 1/2 cup light brown sugar (100 grams)
  • 1/3 cup granulated sugar (65 grams)
  • 1 1/2 cups all purpose flour (190 grams)
  • 1 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 large egg
  • 1 teaspoon pure vanilla extract
  • 1 cup semisweet chocolate chips
  • 1/2 cup M&Ms and
  • 1 large dark chocolate bar any brand


  • Preheat the oven to 350 degrees F. Line 2 cookie sheets with parchment paper.
  • Melt the butter over medium heat in a large saucepan. Remove from heat and add the sugar. Whisk until smooth and let cool for 5 minutes.
  • Mix the flour, baking powder, and salt together and set aside.
  • Whisk the egg and vanilla into the slightly cooled butter mixture, then add the flour mixture. Stir with a rubber scraper until mixed, then (after making sure the mixture is not so warm it will melt the chips) stir in chips.
  • Drop dough by heaping tablespoons onto baking sheets spacing 1 1/2 inches apart.
  • Bake 1 sheet at a time on center rack for about 12 minutes.
  • Carefully transfer to a cooling rack and let cool completely.
  • Melt the chocolate bar in the microwave using 50% power and stirring every 30 seconds. Drizzle over the cookies, then chill the cookies just until the chocolate has set.


I had both types of brown sugar in the pantry so I used a little dark for added molasses flavor. Feel free to just use 100 grams of light brown sugar.
