Indulge in these Ultimate Chocolate Bliss Bars, a rich and decadent treat perfect for any chocolate lover.
Preheat your oven to 350°F (175°C).
Preheating ensures even baking from the start.
In a mixing bowl, combine the flour, confectioners' sugar, and butter using a pastry blender until the mixture resembles coarse crumbs.
Using cold butter helps achieve a crumbly texture.
Press the crust mixture firmly into a 13x9 baking pan to form an even layer.
Use the back of a spoon to smooth out the crust evenly.
Bake the crust in the preheated oven for 15 minutes, then remove and let it cool slightly.
Cooling the crust slightly helps it set before adding the filling.
In a saucepan over low heat, melt the semi-sweet chocolate chips with the sweetened condensed milk and vanilla extract, stirring constantly until smooth.
Stirring constantly prevents the chocolate from burning.
Stir in the chopped walnuts into the chocolate mixture.
Adding nuts provides a delightful crunch to the filling.
Pour the chocolate filling over the baked crust, spreading it evenly with a spatula.
Work quickly as the filling may start to set.
Sprinkle the milk chocolate chips evenly over the filling and gently press them in.
Pressing the chips ensures they adhere well to the filling.
Bake the assembled bars in the oven for an additional 20 minutes.
Baking further sets the layers together.
Allow the bars to cool completely in the pan before cutting into squares.
Cooling completely ensures clean cuts and prevents crumbling.
