1-Getting started with this Twix bars recipe: Begin by preheating your oven to 300 degrees F and lining a 9×13 inch pan with parchment paper for easy removal. This simple prep sets the stage for layers that stack up beautifully.

2-For the shortbread crust: combine 1 cup cold butter, 1 cup powdered sugar, 2 cups flour, and 1 teaspoon vanilla extract in a bowl. Use a pastry blender to mix until it forms a dough, then press it evenly into the pan. Bake for 28-35 minutes until it’s lightly golden, and let it cool completely before moving on.

3-Next, make the caramel by heating 1 cup heavy cream, 1 cup sugar, 1 cup light corn syrup, and 14 ounces sweetened condensed milk in a medium saucepan over medium heat. Stir frequently until it reaches a gentle boil, then cook for 15-20 minutes until it hits the soft ball stage test by dropping some into ice water to form a soft ball. Pour the warm caramel over the cooled shortbread and refrigerate for at least 2 hours.

4-Finally, melt 3 cups chopped milk or dark chocolate with 1 tablespoon butter using a double boiler or microwave in short intervals, stirring until smooth. Spread it over the set caramel layer and refrigerate again until firm. The total time is about 2 hours and 35 minutes, with 35 minutes of active prep, making it ideal for busy schedules.
