Ingredients You’ll Need

Here’s a quick look at what you’ll need to make these easy, decadent toffee bars:

For the Base and Filling:

1 box yellow cake mix: The foundation for the dough, providing a sweet and buttery base.
½ cup unsalted butter, melted 🧈: Adds richness and flavor to the dough.
1 large egg 🍳: Helps bind the dough together for a soft yet structured base.
1 cup toffee bits 🍬: These crunchy bits are the star of the show, adding texture and caramel flavor.
1 can (14 oz) sweetened condensed milk 🥛: For that luscious, creamy filling.
1 cup semi-sweet chocolate chips 🍫: Because what’s better than chocolate melting into a bar?
1 teaspoon vanilla extract 🍦: A dash of vanilla enhances the flavor of the filling.

Step-by-Step Instructions

Step 1: Preheat the Oven

Before you get started with the dough, preheat your oven to 350°F (175°C). Grease a 9×13-inch baking pan with butter or non-stick spray. You don’t want your bars sticking to the pan, so don’t skip this step!

Step 2: Prepare the Dough Base

In a large mixing bowl, combine the yellow cake mix, melted butter, and egg. Stir until all the ingredients are well combined and the mixture forms a soft dough. This will act as the base for your toffee bars.

Tip: The dough will be thick, but that’s exactly how it should be!

Step 3: Press the Dough into the Pan

Take about two-thirds of the dough and press it evenly into the bottom of your prepared baking pan. Use your fingers or the back of a spatula to spread it out evenly so there are no gaps.

Step 4: Add the Toffee Bits

Once your dough is pressed into the pan, sprinkle 1 cup of toffee bits evenly over the dough layer. The toffee adds a delightful crunch and that classic caramel flavor we all love.

Step 5: Make the Chocolate Mixture

Now it’s time for the gooey chocolate layer! In a small saucepan, combine 1 can of sweetened condensed milk, 1 cup of semi-sweet chocolate chips, and 1 teaspoon of vanilla extract. Heat the mixture over low heat, stirring constantly until the chocolate chips have melted and the mixture is smooth.

Tip: Keep the heat low to avoid burning the chocolate. Stir gently but constantly!

Step 6: Layer the Chocolate Over the Toffee

Once your chocolate mixture is ready, pour it evenly over the layer of toffee bits. Use a spatula to smooth the chocolate so that it completely covers the toffee.

Step 7: Crumble the Remaining Dough

Now, take the remaining one-third of the dough and crumble it over the top of the chocolate layer. You don’t need to cover the chocolate completely just scatter the dough bits evenly across the top to create a crumbly topping.

Step 8: Bake the Toffee Bars

Place the baking pan in the preheated oven and bake for 25-30 minutes, or until the top is golden brown and the edges are set. Keep an eye on the bars during the last few minutes to prevent overbaking. Overbaked bars can become too hard, so you want to pull them out once they’re golden and set.

Step 9: Cool and Serve

Once the bars are done baking, remove the pan from the oven and allow them to cool completely in the pan. Once they’re fully cooled, cut them into squares using a sharp knife. Dust with a little powdered sugar or drizzle with extra chocolate if you want to get fancy.

Serving and Storing Your Cake Mix Toffee Bars

Once cooled and cut, these bars are perfect to serve at any gathering. The mix of buttery dough, crunchy toffee, and smooth chocolate will have everyone reaching for seconds!

Storage: Store leftover bars in an airtight container at room temperature for up to 5 days. If you live in a warmer climate, pop them in the fridge to keep them fresh and prevent the chocolate from melting.
Freezing: These bars freeze beautifully! Wrap individual bars in plastic wrap and place them in a freezer-safe container. Freeze for up to 3 months, then thaw at room temperature when you’re ready to enjoy them.
