Directions
Preparing the Shortbread Base:
- Preheat the Oven: Preheat your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper.
- Mix the Dough: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy. Add the vanilla extract and mix until combined. Gradually add the flour and salt, mixing until a soft dough forms.
- Press and Bake: Press the dough evenly into the prepared baking pan. Use your hands or the back of a spoon to flatten and smooth the surface. Bake in the preheated oven for 20-25 minutes, or until the edges are lightly golden. Remove from the oven and let it cool completely.
Preparing the Caramel Layer:
- Melt the Caramel: In a microwave-safe bowl, combine the caramel candies or caramel bits and heavy cream. Microwave in 30-second intervals, stirring between each, until the caramel is fully melted and smooth.
- Spread the Caramel: Pour the melted caramel over the cooled shortbread base, using an offset spatula to spread it evenly. Allow the caramel to set for about 15-20 minutes at room temperature or place it in the refrigerator to speed up the process.
Preparing the Chocolate Topping:
- Melt the Chocolate: In a microwave-safe bowl, combine the chocolate chips and vegetable oil. Microwave in 30-second intervals, stirring between each, until the chocolate is fully melted and smooth.
- Spread the Chocolate: Pour the melted chocolate over the set caramel layer, using an offset spatula to spread it evenly. Allow the chocolate to set completely at room temperature or in the refrigerator.
Cutting and Serving:
- Cut into Bars: Once the chocolate is fully set, lift the Twix cookies out of the pan using the parchment paper. Place them on a cutting board and use a sharp knife to cut them into bars or squares.
Storing Leftovers
Store any leftover Twix Cookies in an airtight container at room temperature for up to 1 week. For longer storage, you can refrigerate them for up to 2 weeks or freeze them for up to 3 months. Allow frozen cookies to thaw at room temperature before serving.
Tips and Variations
- Chocolate Variations: Use milk chocolate or dark chocolate instead of semi-sweet chocolate for a different flavor profile.
- Caramel Alternatives: Try making your own caramel from scratch for a homemade touch, or use dulce de leche for a creamy caramel layer.
- Add a Sprinkle: For a festive touch, sprinkle sea salt, crushed nuts, or sprinkles over the chocolate layer before it sets.
- Shape Options: Use a cookie cutter to create fun shapes instead of bars for a unique presentation.
