Description

Heavenly Cake Mix Toffee Bars packed with rich toffee, simple baking steps, and irresistible taste – perfect for any occasion!


Ingredients

Scale
  • 1 box (15.25 oz/432g) yellow cake mix
  • 1/2 cup (113g) unsalted butter, melted
  • 1 large egg, at room temperature
  • 1 teaspoon vanilla extract
  • 1 1/2 cups (270g) toffee bits, divided (like Heath or Skor bits)
  • 1 can (14 oz/396g) sweetened condensed milk
  • 1/2 cup (85g) semi-sweet chocolate chips (optional)

Instructions

  1. Step 1: Prepare Your Kitchen Preheat your oven to 350°F (175°C) and line a 9×13 inch baking pan with parchment paper, leaving overhang on the sides for easy removal. Gather all your ingredients to ensure a smooth baking process for your Heavenly Cake Mix Toffee Bars.
  2. Step 2: Create the Base Layer In a large bowl, combine the cake mix, melted butter, egg, and vanilla extract. The mixture will be thick and somewhat crumbly—this is exactly what you want! Mix until no dry spots remain. Reserve 1 cup of this mixture for the topping. Press the remaining dough firmly into your prepared pan, creating an even layer that covers the entire bottom.
  3. Step 3: Add the Toffee Layer Sprinkle 1 cup of the toffee bits evenly over your base layer. They’ll look like a lot, but they’ll melt into delicious pockets of flavor! Pour the sweetened condensed milk over the toffee bits, spreading it to cover the entire surface but stopping about 1/2 inch from the edges (this prevents sticking to the sides of the pan).
  4. Step 4: Create the Topping Mix the reserved cup of dough with the remaining 1/2 cup of toffee bits. Crumble this mixture over the condensed milk layer, creating a rustic, uneven topping. Don’t worry about covering the entire surface—the gaps will allow you to see the gooey middle layer, which is part of the charm of these Heavenly Cake Mix Toffee Bars.
  5. Step 5: Bake to Golden Perfection Bake for 25-30 minutes until the top is golden brown and the edges are slightly darker. The center might still appear slightly jiggly—that’s perfect! It will continue to set as it cools. If adding chocolate chips, sprinkle them over the top immediately after removing from the oven so they melt slightly.
  6. Step 6: Cool and Slice Allow the bars to cool completely in the pan before lifting out using the parchment paper overhang. Cut into squares or rectangles using a sharp knife. For the cleanest cuts, refrigerate for 30 minutes before slicing.

Notes

Fresh ingredients will always yield the best flavor results.
