Servings 4 dozen


Brownie Batter:

  • 1 package (4 ounces) Baker's Unsweetened Chocolate 4 ounces Baker's Unsweetened Chocolate
  • 3/4 cup unsalted butter
  • 1 cup sugar
  • 1 cup brown sugar packed
  • 2 eggs
  • 1 teaspoons vanilla
  • 1 cup all-purpose flour

Peanut Butter Cookie Dough:

  • 1 cup unsalted butter softened
  • 1 cup sugar
  • 1 cup brown sugar
  • 3/4 cup creamy peanut butter
  • 2 eggs
  • 2 teaspoon vanilla
  • 3 cups all-purpose flour
  • 1 teaspoon baking soda
  • 2 teaspoons hot water
  • 1 teaspoon salt


  1. Begin preparing the brownie batter by adding the chocolate and butter to a large microwave-safe bowl. Microwave on high for 2-3 minutes, stirring every 30 seconds until the chocolate and butter are melted and smooth. Stir in the sugars.
  2. Add the eggs and vanilla and mix until smooth. Then add the flour and stir to combine. Refrigerate the brownie batter until it becomes firm - 4-5 hours or overnight.
  3. Now prepare the peanut butter cookie dough with an electric mixer by creaming together the butter, sugar, and brown sugar. Then, beat in the peanut butter.
  4. Beat in the eggs, one at a time; then stir in the vanilla.
  5. Dissolve the baking soda in the hot water. Add that to the batter, along with the salt. Finally, mix in the flour. Refrigerate for 1-2 hours or overnight.
  6. When ready to bake, preheat the oven to 350 degrees F and remove the dough from the refrigerator.
  7. Form the brownie batter into 3/4-inch balls. Then cover the brownie balls with the peanut butter dough. (I found it easiest to first roll the peanut butter dough into a 1 1/2-inch ball and then flatten it and wrap it around a brownie batter ball.) Cover the brownie ball completely.
  8. Place the balls of dough to an ungreased cookie sheet and flatten slightly. Bake for 10-12 minutes or until the edges of the cookie begin to brown. Cool on a baking rack.
  9. Store the cookies in an airtight container.
