How to Make Cake Mix Toffee Bars (Step-by-Step Guide)

cake mix bars

Are you ready to bake a batch of irresistibly chewy, chocolatey, and crunchy Cake Mix Toffee Bars? Is this recipe easy for beginners? Yes! This foolproof method ensures perfect results every time.

Follow these simple steps, and in just 30 minutes, your kitchen will be filled with the heavenly aroma of buttery toffee and melted chocolate.

Step 1: Preheat & Prep

First things first—preheat your oven to 350°F (175°C).

Then, line a 9×13-inch baking pan with parchment paper or lightly grease it with butter. This prevents sticking and makes cleanup a breeze!

Pro Tip: If you want clean, even bars, let them cool completely before slicing!

Step 2: Make the Cake Mix Base

In a large mixing bowl, combine:

  • Cake mix (yellow, chocolate, or vanilla)
  • Melted butter (½ cup)
  • Egg (1 large)

Mix until a soft dough forms. It might be a little crumbly—that’s okay! Press the mixture evenly into the prepared pan, making sure to reach the edges.

Step 3: Add the Sweet Layer

Now, for the secret ingredient—sweetened condensed milk!

  • Drizzle the entire can (14 oz) evenly over the cake mix layer.
  • Sprinkle the chocolate chips and toffee bits generously on top.

This creates that gooey, caramelized magic in every bite!

Step 4: Bake to Perfection

Place the pan in the preheated oven and bake for 22-25 minutes, or until the edges turn a light golden brown.

How do you know when they’re done?

  • The edges should be firm but the center will still look slightly soft—that’s what gives them that perfect chewy texture!

Step 5: Cool, Slice & Enjoy!

Once baked, let the bars cool completely in the pan before slicing. This helps the layers set properly and makes cutting easier.

Serving Ideas:

  • Enjoy warm with a scoop of vanilla ice cream.
  • Drizzle with extra caramel for a decadent twist.
  • Sprinkle with sea salt for a sweet-and-salty flavor boost!
