Makes 32 bars
14-ounce can sweetened condensed milk
large egg, beaten
pure vanilla extract
pecans, coarsely chopped
semisweet chocolate chips
toffee-and-chocolate baking pieces (such as Heath or Skor)
- Heat oven to 350°F. Combine the flour, confectioners' sugar, and butter in the bowl of a food processor. Pulse until a crumbly dough is formed. Press the dough firmly into a greased 9-by-13-inch pan. Bake until just golden, about 13 minutes.
- Whisk together the condensed milk, egg, and vanilla. Pour the filling over the baked crust. Sprinkle the pecans, chocolate chips, and toffee pieces evenly over the filling. Bake until the filling is set, the edges are golden brown, and the toffee is melted, about 25 minutes.
- Cool completely in the refrigerator, about 2 hours. Cut into 32 bars.
