Ingredients:

  • 1 cup (226g) unsalted butter, softened
  • 1 cup (200g) granulated sugar
  • 1 cup (220g) packed light brown sugar
  • 2 large eggs
  • 1 teaspoon (5ml) vanilla extract
  • 1 cup (240ml) creamy peanut butter
  • 2 1/2 cups (300g) all-purpose flour
  • 1 teaspoon (5ml) baking soda
  • 1/2 teaspoon (2.5ml) salt
  • 1/2 cup (120ml) creamy peanut butter
  • 2 tablespoons (30g) unsalted butter, softened
  • 1 cup (120g) powdered sugar
  • 1-2 tablespoons (15-30ml) milk
  • 1 cup (170g) semi-sweet chocolate chips (optional)
  • 1 teaspoon (5ml) coconut oil (optional)

Instructions:

  1. Cream the butter and sugars: Combine softened butter, granulated sugar, and brown sugar in a bowl. Cream together until light and fluffy.
  2. Add wet ingredients: Beat in the eggs one at a time, then stir in the vanilla extract and peanut butter.
  3. Combine dry ingredients: In a separate bowl, whisk together flour, baking soda, and salt.
  4. Combine wet and dry: Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Do not overmix!
  5. Chill the dough: Cover the dough and chill in the refrigerator for at least 30 minutes (or longer, up to 24 hours).
  6. Preheat oven and prepare muffin tin: Preheat oven to 375°F (190°C/Gas Mark 5). Line a muffin tin with paper liners or grease it well.
  7. Shape the cups: Roll dough into balls (about 1.5-2 tablespoons each). Press each ball into the bottom and up the sides of the muffin cups to form a cup shape.
  8. Bake the cups: Bake for 12-15 minutes, or until the edges are golden brown and the centers are set.
  9. Cool the cups: Let the cookie cups cool in the muffin tin for a few minutes, then transfer them to a wire rack to cool completely.
  10. Prepare the filling: Beat peanut butter and softened butter together until smooth. Gradually add powdered sugar, alternating with milk, until the filling reaches a pipe-able consistency.
  11. Fill the cups: Once the cookie cups are completely cooled, fill each cup with the peanut butter filling using a piping bag or spoon.
  12. Melt Chocolate (Optional): If using chocolate, melt it in a double boiler or microwave with coconut oil until smooth.
  13. Top with Chocolate (Optional): Drizzle the melted chocolate over the peanut butter filling.
  14. Chill (Optional): Place cookie cups in the refrigerator for 15-20 minutes to allow chocolate to set. Enjoy your delicious peanut butter cookie cups!
