Loaded with toasted pecans, these Pecan Toffee Bars have a shortbread crumb base and a caramel, pecan center. Topped with melted milk chocolate, these bars are just heavenly! This is a holiday confection that will be difficult to share and part with. Maybe it's a good idea to make a double batch of these after all!
Preheat your oven to 350 degrees F. Line a 9×13-inch baking pan with parchment paper. Set aside.
Measure the flour, brown sugar, and butter into a mixing bowl. Beat until well combined. The mixture should look dry - almost like lightly wet sand.
Transfer the mixture to the prepared baking pan and lightly press into the pan to form a flattened crust.
Sprinkle over the toasted whole pecans. Set aside.
For the Middle:
Next, in a saucepan, measure in the butter and brown sugar. Over medium heat, cook the butter and brown sugar, stirring constantly, until the mixture begins to bubble. From that point, cook for one minute while stirring.
Pour this mixture into the baking pan over the pecans.
Bake for 18 minutes or until the top is bubbling. Remove the pan from the oven and set aside.
For the Top:
Place the chocolate and vegetable oil into a microwave-safe bowl. Microwave it at half speed for 30 seconds. Stir well and microwave in 30-second increments, stirring between each increment, until melted and smooth.
Pour the chocolate over the pecan and caramel layer. Use a spatula to smooth it out.
Set aside to cool for 2-4 hours.
Cut into squares. Transfer the squares to a food-safe container and keep refrigerated.
