Ingredients
  

For the Shortbread:
  • 1 stick butter softened
  • 1/2 cup granulated sugar
  • 1 teaspoon vanilla extract
  • 1 cup flour
For the Caramel Layer:
  • 25 caramels unwrapped (I used Kraft)
  • 2 tablespoons peanut butter
  • 1 tablespoon heavy cream
For the Chocolate Topping:
  • 1 1/4 cups chocolate chips (milk or semi-sweet)
  • 2 tablespoons peanut butter for drizzling
  • 1/2 cup mini Reese's Pieces (optional)

Equipment

  • Mixing Bowl
  • 9x9 inch Baking Pan
  • Double boiler or microwave-safe bowl
  • Spatula
  • Measuring cups and spoons

Method
 

Instructions:
  1. Step 1: Preheat your oven to 350°F (175°C). In a mixing bowl, cream together 1 stick of softened butter and 1/2 cup of granulated sugar until light and fluffy. Add in 1 teaspoon of vanilla extract and mix well. Gradually add 1 cup of flour until combined. The mixture will be crumbly but should hold together when pressed.
  2. Step 2: Press the shortbread mixture evenly into the bottom of your greased 9x9 inch baking pan. Bake for 15-20 minutes, or until the edges are lightly golden. Remove from the oven and let it cool slightly.
  3. Step 3: In a double boiler or microwave-safe bowl, combine 25 unwrapped caramels, 2 tablespoons of peanut butter, and 1 tablespoon of heavy cream. Heat gently until melted and smooth, stirring frequently. Once melted, pour the caramel over the baked shortbread layer, spreading it evenly.
  4. Step 4: In the same double boiler or microwave, melt 1 1/4 cups of chocolate chips until smooth. Pour the melted chocolate over the caramel layer, spreading it evenly. If you’re using them, sprinkle 1/2 cup of mini Reese's Pieces on top for a fun crunch and color.
  5. Step 5: In a small bowl, melt 2 tablespoons of peanut butter and drizzle it over the chocolate layer for an extra touch of peanut buttery goodness.
  6. Step 6: Refrigerate the bars for at least 2 hours to allow everything to set. Once set, lift the bars out of the pan using the edges of the parchment paper. Cut into squares and enjoy your homemade Peanut Butter Caramel Shortbread Bars!
