½ cup unsalted butter, melted (for that irresistible richness)
1 large egg (to bind the magic together)

½ cup sweetened condensed milk (the glue that holds the layers in place)
1 tsp vanilla extract (because vanilla makes everything better)
A pinch of salt (to balance the sweetness)

Ingredient Highlights

Preparation Time

Prep Time: 10 minutes
Cook Time: 25–30 minutes
Total Time: 35–40 minutes

Step-by-Step Preparation Instructions

Step 1: Preheat & Prep
Preheat your oven to 350°F (175°C). Grease an 8×8-inch or 9×9-inch baking pan, or line it with parchment paper for easy removal.

Step 2: Make the Crust
In a large mixing bowl, combine the cake mix, melted butter, egg, vanilla extract, and salt. Stir until a thick, crumbly dough forms. Press this evenly into the bottom of your prepared pan.

Step 3: Layer the Goodness
Pour the sweetened condensed milk over the crust, spreading it gently with a spatula. Sprinkle the toffee bits evenly on top, pressing them lightly into the milk.

Step 4: Bake to Perfection
Bake for 25–30 minutes, or until the edges turn golden brown and the center is just set. A toothpick inserted into the crust should come out clean.

Step 4: Cool & Cut
Let the bars cool completely in the pan (about 1 hour). Use a sharp knife to slice into squares or rectangles.

Additional Tips

Toffee hack: If you can’t find toffee bits, crush chocolate-covered toffee bars (like Heath) into small pieces.
Doneness test: The bars will firm up as they cool, so avoid overbaking.
Pan size matters: Use a 9×9-inch pan for thinner, crispier bars or an 8×8-inch for thicker, chewier ones.

Recipe Variations

Chocolate lover’s twist: Use chocolate cake mix and add chocolate chips to the topping.
Nutty crunch: Stir ½ cup chopped pecans or almonds into the crust.
Salty-sweet: Sprinkle coarse sea salt over the toffee layer before baking.
