Description

Cake Mix Toffee Bars – A shortcut to decadence! Buttery yellow cake mix layered with melty toffee, chocolate chips, and creamy condensed milk—baked into gooey, golden bars that taste homemade. Perfect for last-minute treats or sweet cravings

Ingredients

1 box yellow cake mix
1/2 cup unsalted butter, melted
1 large egg
1 cup toffee bits
1/2 cup semi-sweet chocolate chips
1 (14 oz) can sweetened condensed milk
1/2 tsp vanilla extract
Pinch of sea salt

Instructions

1. Preheat the Oven

Preheat to 350°F (175°C).
Grease or line a 9×13-inch baking dish with parchment paper for easy removal.

2. Make the Dough

In a medium bowl, combine cake mix, melted butter, and egg.
Mix until a thick dough forms.

3. Form the Crust

Press 2/3 of the dough evenly into the bottom of the prepared pan to form the base layer.

4. Layer the Filling

In a separate bowl, whisk together sweetened condensed milk, vanilla extract, and sea salt.
Sprinkle toffee bits and chocolate chips evenly over the crust.
Pour the condensed milk mixture over the top.

5. Add the Topping

Crumble the remaining dough over the top layer. It doesn’t have to cover completely.

6. Bake

Bake for 25–30 minutes until golden brown and bubbly at the edges.

7. Cool and Slice

Let bars cool completely in the pan.
For clean slices, chill in the fridge for 1 hour before cutting into squares.

Notes

For extra caramel flavor, use a caramel-flavored sweetened condensed milk if available.
Be sure not to overbake—the center will set as it cools.
