Replicate the classic candy bar with these homemade Twix bars featuring a buttery shortbread base, gooey caramel, and a rich milk chocolate coating. These bars are easy to make and taste better than store-bought.

Ingredients

  • For the Shortbread Base: 1 cup (2 sticks) unsalted butter, softened; 1/2 cup granulated sugar; 2 cups all-purpose flour; 1/4 teaspoon salt
  • For the Caramel Layer: 1 cup (2 sticks) unsalted butter; 1 cup packed light brown sugar; 1 (14 ounce) can sweetened condensed milk; 1 teaspoon vanilla extract
  • For the Chocolate Coating: 12 ounces milk chocolate chips; 1 tablespoon coconut oil (optional, for smooth dipping)

Instructions

  1. Prepare the Shortbread: Preheat your oven to 350°F (175°C). Line an 8×8 inch baking pan with parchment paper, leaving an overhang for easy removal.
  2. Beat the butter and sugar together in a large bowl until light and fluffy. Gradually add the flour and salt, mixing until just combined into a dough.
  3. Press the shortbread dough evenly into the bottom of the prepared pan. Bake for 18 to 20 minutes, or until the edges are lightly golden. Let cool slightly while you make the caramel.
  4. Make the Caramel: In a medium saucepan, melt the butter over medium heat. Stir in the brown sugar until dissolved. Add the sweetened condensed milk.
  5. Bring the mixture to a gentle boil, stirring constantly. Reduce the heat to low and cook for 5 to 7 minutes, stirring often, until the mixture thickens slightly. Remove from heat and stir in the vanilla extract.
  6. Pour the warm caramel evenly over the cooled shortbread crust. Return the pan to the oven and bake for an additional 10 minutes. The caramel should look bubbly.
  7. Cool Completely: Remove the pan from the oven and let it cool completely on a wire rack, then chill in the refrigerator for at least 2 hours, or until the caramel is firm.
  8. Melt the Chocolate: Place the milk chocolate chips and coconut oil (if using) in a microwave-safe bowl. Microwave in 30-second intervals, stirring well after each, until smooth.
  9. Cut the chilled caramel shortbread into bars of your desired size. Dip each bar into the melted chocolate, ensuring it is fully coated. Place the coated bars back onto the parchment-lined pan or a cooling rack.
  10. Let the chocolate set completely at room temperature or chill briefly until firm before serving. Slice and enjoy your homemade candy bar replica.

Notes

  • For a cleaner cut, run a large knife under hot water and dry it before slicing the chilled bars.
  • If you prefer a darker chocolate flavor, substitute semi-sweet chocolate chips for the milk chocolate.
  • Chill the bars for at least 4 hours for the easiest handling when cutting and dipping.
