Ingredients Equipment Method Notes

Ingredients
  

  • 1 box 15.25 oz yellow cake mix
  • 1 large egg
  • 6 tablespoons ⅓ cup unsalted butter, melted
  • 1 14 oz can sweetened condensed milk
  • 2 cups toffee bits such as Heath bits or chopped toffee

Equipment

  • 9×13-inch baking pan
  • Mixing bowl
  • Measuring spoons and cups
  • Spatula or spoon
  • Oven

Method
 

Preheat and Prepare
  1. Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with cooking spray or line it with parchment paper for easy removal.
Mix the Base
  1. In a mixing bowl, combine the yellow cake mix, melted butter, and egg. Stir until the mixture forms a dough-like consistency.
Press into Pan
  1. Evenly press the dough into the bottom of the prepared baking pan, ensuring it covers the entire surface.
Add Toffee Bits
  1. Sprinkle the toffee bits evenly over the dough layer.
Pour Sweetened Condensed Milk
  1. Pour the sweetened condensed milk evenly over the toffee bits, ensuring they are well-coated.
Bake
  1. Bake in the preheated oven for 25–30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Cool and Slice
  1. Allow the bars to cool completely in the pan before slicing into squares.

Notes

  • Make-Ahead: These bars can be made a day in advance and stored in an airtight container at room temperature.
  • Freezing: For longer storage, freeze the bars in a single layer, then transfer to a freezer-safe container for up to 3 months.
