Homemade Twix Bars are SO much better than the store-bought candy with a slightly crumbly cookie layer, chewy caramel, and smooth, rich chocolate top layer.
1/2cup(1 stick) chilled unsalted butter, cut into 1/2-inch cubes
1tablespoonice water
1large egg yolk
Caramel Topping:
6tablespoons(3/4 stick) unsalted butter, diced
1/2cuppacked light brown sugar
1 14-ouncecan sweetened condensed milk
2tablespoonsdark corn syrup
1teaspoonvanilla extract
Chocolate Glaze:
6ouncesbittersweet or semisweet chocolate, chopped
3tablespoonsheavy whipping cream
Flaked sea salt (such as Maldon)
Instructions
For the crust:
Preheat oven to 350 degrees F. Coat an 8x8-inch baking pan with nonstick spray. Line with parchment, leaving enough to overhang, and spray parchment with nonstick spray.
Blend flour, sugar, cornstarch, and salt in food processor. Add butter. Pulse until coarse meal forms. Add 1 tablespoon ice water and egg yolk. Blend until moist clumps form. Press dough onto bottom (not sides) of prepared pan; pierce all over with a fork. Bake until golden, piercing if crust bubbles, 22 minutes. Cool completely.
For the caramel topping:
Melt butter in a medium saucepan. Add brown sugar, stir until dissolved. Whisk in milk, corn syrup, and vanilla and let come to a boil. Attach a clip-on candy thermometer to the side of the pan. Boil gently, whisking constantly, until caramel is pale golden and thick and thermometer registers 225 degrees F, about 8 minutes. Pour caramel over cooled crust, spreading evenly to the edges. Cool 15 minutes.
For the chocolate glaze:
Meanwhile, melt chocolate with cream in microwave in 15-second bursts, stirring until smooth. Be careful not to overheat. Spread chocolate over warm caramel; sprinkle with sea salt. Refrigerate until chocolate is set, at least 1 hour. Can be made 3 days ahead; cover and keep refrigerated. Cut dessert into long bars before serving.
