Ingredients
-
1 box (15.25 oz) yellow cake mix
-
½ cup (1 stick) unsalted butter, melted
-
1 large egg
-
1 can (14 oz) sweetened condensed milk
-
1 cup semi-sweet chocolate chips
-
1 cup toffee bits (such as Heath bits)
-
½ cup chopped pecans or walnuts (optional)
Instructions
Step 1: Preheat & Prepare Pan
-
Preheat oven to 350°F (175°C).
-
Line a 9×13-inch baking pan with parchment paper or lightly grease it with non-stick spray.
Step 2: Make the Crust
-
In a large bowl, combine cake mix, melted butter, and egg.
-
Mix until a thick dough forms.
-
Press ⅔ of the dough evenly into the bottom of the prepared pan.
Step 3: Add the Filling
-
Pour sweetened condensed milk evenly over the crust.
-
Sprinkle chocolate chips, toffee bits, and nuts (if using) on top.
-
Crumble the remaining dough over the filling (it won’t fully cover it, which is fine).
Step 4: Bake
-
Bake for 23-25 minutes, or until the edges are golden brown and the center is set.
Step 5: Cool & Slice
-
Let the bars cool completely (about 1 hour) before slicing into squares.
