Pecan Toffee Squares Recipe

Preheat an oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking pan. Mix sweetened condensed milk 1 egg pecans toffee bits and vanilla extract in a bowl until well blended; set aside.

Cut the butter and 1 egg into the yellow cake mix in a large bowl with a knife or pastry blender until the mixture resembles coarse crumbs. Press the crumbs into the prepared pan to form a bottom layer.

Bake in the preheated oven until firm about 7 minutes. Spread pecan filling over the baked bottom layer then continue baking until the filling has set 22 to 30 minutes. Cool completely on a wire rack. Serve with whipped topping.
