Cake Mix Toffee Bars (Printable)

Buttery bars with toffee and chocolate on a cake mix base

# What You'll Need:

→ Base

01 - 1 box (15.25 oz) yellow cake mix
02 - 1/2 cup unsalted butter, melted
03 - 1 large egg

→ Topping

04 - 1 cup semi-sweet chocolate chips
05 - 1 cup toffee bits
06 - 1/2 cup chopped pecans (optional)

# Directions:

01 - Preheat oven to 350°F. Grease a 9x13 inch baking pan or line with parchment paper.
02 - Combine cake mix, melted butter, and egg in a large bowl. Mix until soft dough forms.
03 - Press dough evenly into prepared baking pan to form base layer.
04 - Bake for 15 minutes until just set but not browned.
05 - Remove from oven. Sprinkle chocolate chips evenly over hot base; let sit 2-3 minutes until melted, then spread gently with spatula.
06 - Sprinkle toffee bits and chopped pecans (if using) over melted chocolate.
07 - Return to oven for 8-10 minutes until toppings are slightly bubbly and edges are golden.
08 - Let cool completely in pan before cutting into bars.

# Expert Advice:

01 -
  • The hardest part is waiting for them to cool down enough to cut.
  • That cake mix trick means zero measuring and practically zero effort.
02 -
  • I once cut these while they were still slightly warm and the chocolate smeared across everything. Patience pays off here.
  • The hot crust melts the chips beautifully so no need to microwave them separately first.
03 -
  • Parchment paper with overhanging edges makes lifting the whole batch out so much easier for cutting.
  • Press the dough firmly and evenly, especially in the corners, so the bars bake uniformly.
