1 1/2 cups toffee bits, divided
1/2 cup semi-sweet chocolate chips

Baking time: 25-30 minutes
Cooling time: 1 hour
Total time: 1 hour 45 minutes (30% faster than traditional toffee bar recipes that require making toffee from scratch)

Step-by-Step Instructions

Step 1: Prepare Your Baking Pan

Preheat your oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving some overhang for easy removal. Spray lightly with non-stick cooking spray. This preparation ensures your bars will release perfectly without sticking.

Step 2: Create the Cake Mix Base

In a large bowl, combine the cake mix, melted butter, egg, and vanilla extract. The mixture will be thick and somewhat crumbly – that’s exactly what you want! Press about 2/3 of this mixture firmly into the bottom of your prepared pan, creating an even layer. Reserve the remaining 1/3 for the topping.

Step 3: Add the Condensed Milk Layer

Pour the sweetened condensed milk evenly over the cake mix base. Use a spatula to spread it within 1/4 inch of the edges. Pro tip: slightly warming the condensed milk makes it easier to spread without disturbing your base layer.

Step 4: Sprinkle the Toffee and Chocolate

Sprinkle 1 cup of the toffee bits and all of the chocolate chips evenly over the condensed milk layer. These will melt slightly during baking, creating pockets of gooey deliciousness throughout your bars.

Step 5: Add the Crumble Topping

Take the remaining cake mix mixture and crumble it over the top of your layered bar. Don’t worry about covering completely – the gaps will allow you to see the delicious layers underneath and create a more interesting texture.

Step 6: Finish with More Toffee

Sprinkle the remaining 1/2 cup of toffee bits over the crumble topping. This final layer will create that signature crunch that makes Cake Mix Toffee Bars so irresistible.

Step 7: Bake to Perfection

Bake in your preheated oven for 25-30 minutes, until the edges are golden brown and the center is set but still slightly soft. Be careful not to overbake, as these bars should maintain a slightly chewy texture.

Step 8: Cool Completely

Allow the bars to cool completely in the pan, about 1 hour. This cooling time is crucial – it allows the layers to set properly for clean cutting. For best results, refrigerate for 30 minutes before cutting.

FAQs

Can I use a different flavor of cake mix?
Absolutely! While yellow cake mix provides a classic buttery base, chocolate or white cake mix work wonderfully too. Each creates a different flavor profile while maintaining the perfect texture.

How do I know when the bars are done baking?
Look for golden brown edges and a set but slightly soft center. A toothpick inserted in the middle should come out with a few moist crumbs but no wet batter.

Can I make these bars ahead of time for a party?
Yes! These bars actually improve in flavor after 24 hours, making them perfect for make-ahead desserts. Store them in an airtight container until ready to serve.

Why did my bars turn out too crumbly?
This usually happens when there’s too much cake mix relative to the butter and egg. Make sure to measure accurately and don’t pack the cake mix when measuring.

Are there nut-free alternatives to toffee bits?
Most commercial toffee bits are nut-free, but always check packaging. Alternatively, butterscotch chips or caramel bits make excellent substitutions for those with nut allergies.
