Make copycat Twix bars with a shortbread base, gooey caramel layer, and chocolate coating.

Ingredients

Scale
  • 1 cup (2 sticks) unsalted butter, softened
  • 1/2 cup granulated sugar
  • 2 cups all-purpose flour
  • 1/4 teaspoon salt
  • 1 (14 ounce) can sweetened condensed milk
  • 1/2 cup light corn syrup
  • 1 cup packed light brown sugar
  • 1 teaspoon vanilla extract
  • 1/4 cup water
  • 1 1/2 cups semi-sweet chocolate chips
  • 1 tablespoon vegetable shortening

Instructions

  1. For the shortbread base, beat the softened butter and granulated sugar in a large bowl until creamy.
  2. Add the flour and salt. Mix on low speed until the dough just comes together.
  3. Press the dough evenly into the bottom of a 9×13 inch baking pan lined with parchment paper.
  4. Bake the shortbread at 350 degrees F for 15 to 18 minutes, or until the edges are lightly golden. Let it cool slightly.
  5. For the caramel, combine the sweetened condensed milk, corn syrup, brown sugar, vanilla extract, and water in a medium saucepan.
  6. Cook over medium heat, stirring constantly, until the mixture reaches 240 degrees F on a candy thermometer (firm ball stage). This takes about 8 to 10 minutes.
  7. Pour the hot caramel evenly over the warm shortbread base. Let it set at room temperature for about 1 hour, or until the caramel is firm enough to cut.
  8. For the chocolate coating, melt the chocolate chips and shortening together in a microwave-safe bowl in 30-second intervals, stirring until smooth.
  9. Cut the cooled caramel layer into bars of your desired size.
  10. Dip each bar into the melted chocolate, ensuring full coverage. Place the coated bars on a parchment-lined baking sheet.
  11. Refrigerate the bars for at least 30 minutes, or until the chocolate is set.

Notes

  • You can chill the shortbread base for 30 minutes before baking for easier handling.
  • For cleaner cuts, run your knife under hot water and dry it between slices when cutting the caramel layer.
  • Store the finished bars in an airtight container in the refrigerator.
