Step-by-Step: How to Make Cake Mix Toffee Bars

  1. Preheat Your Oven
    Set your oven to 350°F (175°C) and lightly grease a 9×13-inch baking pan or line with parchment paper.
  2. Make the Crust
    In a bowl, combine the yellow cake mix, melted butter, and 1 egg. Stir until a soft dough forms.
  3. Form the Base
    Press about two-thirds of the dough evenly into the bottom of the prepared baking pan.
  4. Add Toffee Layer
    Sprinkle the toffee bits evenly over the base layer.
  5. Make the Chocolate Filling
    In a saucepan over low heat (or a microwave-safe bowl), combine the sweetened condensed milk, chocolate chips, and vanilla extract. Stir until smooth and fully melted.
  6. Layer It Up
    Pour the chocolate filling over the toffee bits and spread it out gently.
  7. Add the Crumble Topping
    Crumble the remaining dough on top of the chocolate layer. Don’t worry if some chocolate shows through.
  8. Bake to Perfection
    Bake for 25–30 minutes, or until the top is golden brown and the center is set.
  9. Cool Before Cutting
    Allow the bars to cool completely before slicing into squares. This helps the layers hold together for clean cuts.

Tips and Tricks for Perfect Bars Every Time

  • Don’t Overmix the Dough: Mix just until combined to keep the crust tender.
  • Watch for Doneness: The edges should be golden and the center set, but still slightly soft.
  • Cool Completely: Cutting while warm can make the bars fall apart. Wait until fully cool.
  • Storage: Keep in an airtight container at room temperature for up to 3 days.
  • Freezer-Friendly: Freeze in layers between parchment for up to 2 months.

Pairings, Toppings, and Fun Variations

  • Serve With: Vanilla ice cream, whipped cream, or a glass of cold milk.
  • Top With: Caramel drizzle, sea salt flakes, or chopped nuts.
  • Flavor Variations:
    • Add a handful of chopped pecans for crunch.
    • Mix in a few butterscotch chips for extra sweetness.
    • Use dark chocolate chips for a richer, bittersweet twist.
  • Make-Ahead Tips: These bars taste even better the next day. Perfect for prepping ahead of events.

Frequently Asked Questions About Cake Mix Toffee Bars

Can I use a different flavor of cake mix?

Yes, while yellow cake mix is the traditional base, you can experiment with vanilla, butter pecan, or even chocolate cake mix for a different flavor profile. Just make sure to use a similar-sized box and adjust sweetness accordingly if your mix is already very sweet.

How do I keep the bars from falling apart when cutting?

Let the bars cool completely in the pan before slicing. For best results, refrigerate for 30 minutes after cooling to firm up the layers. Use a sharp knife and wipe it clean between cuts for cleaner edges.

Can Cake Mix Toffee Bars be frozen?

Absolutely. Once cooled and sliced, layer the bars between parchment paper in an airtight container. They freeze well for up to 2 months. To thaw, let them sit at room temperature for 30–60 minutes — no reheating needed.
