Cake Mix Toffee Bars: A Beginner-Friendly Dessert That Tastes Like Magic
These Cake Mix Toffee Bars are the easiest way to create a rich, chewy, and buttery dessert! 🍫✨ Made with a simple cake mix base, melty chocolate, and crunchy toffee bits, they’re quick to make but taste like they came from a bakery! Perfect for any occasion! 😍🥄
- Total Time: 35 minutes
- Yield: 16–20 bars 1x
Ingredients
- 1 box yellow cake mix
- ½ cup melted butter
- 1 large egg
- 1 can (14 oz) sweetened condensed milk
- 1 cup semi-sweet chocolate chips
- 1 cup toffee bits
- ½ cup chopped nuts (optional)
- ½ teaspoon vanilla extract (optional, for added depth of flavor)
Instructions
1. Preparing the Baking Pan
Preheat the oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal. Using parchment paper allows the bars to be lifted out effortlessly and makes cleanup simpler.
2. Mixing the Base Layer
In a large mixing bowl, combine the yellow cake mix, melted butter, and egg. Stir until well incorporated. The mixture should be crumbly but hold together when pressed.
3. Creating the Crust
Take about two-thirds of the prepared cake mix mixture and press it evenly into the bottom of the greased baking pan. Pressing firmly ensures a sturdy base that holds the layers together after baking.
4. Adding the Sweetened Condensed Milk
Pour the sweetened condensed milk evenly over the crust, using a spatula to spread it gently to cover the surface. This layer contributes to the bars’ creamy texture and sweetness.
5. Adding the Chocolate and Toffee Layers
Sprinkle the semi-sweet chocolate chips and toffee bits evenly over the condensed milk layer. If adding nuts, distribute them at this stage as well.
6. Adding the Final Crumble Layer
Take the remaining cake mix mixture and crumble it over the top of the chocolate and toffee layer. This step gives the bars a slightly crunchy texture on top while allowing some of the filling to peek through.
7. Baking
Place the pan in the preheated oven and bake for 25–30 minutes, or until the edges are golden brown. The center may look slightly soft, but it will firm up as it cools.
8. Cooling and Slicing
Remove the bars from the oven and allow them to cool completely in the pan before slicing. Cutting too soon may result in a messy texture. Once cooled, cut into squares or rectangles, depending on preference.
Notes
- Ensuring Even Baking: If using a glass baking dish, reduce the oven temperature slightly to prevent overbrowning. Glass retains heat longer than metal, which can cause the edges to cook faster.
- Preventing Overcooking: The bars should have slightly crispy edges and a softer center when removed from the oven. They will continue to set as they cool, so avoid overbaking to maintain a chewy texture.
- Substituting Cake Mix Flavors: Experimenting with different cake mix flavors can create unique variations. A chocolate cake mix base makes a double chocolate version, while a spice cake mix adds warmth to the flavor profile.
- Melting Butter Properly: Melt butter in short bursts in the microwave or over low heat on the stove to avoid overheating. Allowing it to cool slightly before mixing with the cake mix prevents altering the dough texture.
- Cutting the Bars Cleanly: For the best presentation, chill the bars in the refrigerator for 15–20 minutes before slicing. Using a sharp knife and wiping it clean between cuts ensures neater slices.
- Prep Time: 10 minutes
- Cook Time: 25 minutes

Ingredients and Preparation
Before starting, it is essential to have all ingredients measured and ready to make the process smoother. Here is everything needed to create these delicious bars:
Ingredients:
- 1 box yellow cake mix
- ½ cup melted butter

- 1 can (14 oz) sweetened condensed milk
- 1 cup semi-sweet chocolate chips
- 1 cup toffee bits
- ½ cup chopped nuts (optional)
- ½ teaspoon vanilla extract (optional, for added depth of flavor)
Alternative Ingredient Suggestions:
- Cake Mix: Yellow cake mix works best, but vanilla or butter cake mix can be used for slight variations in flavor.

- Toffee Bits: If toffee bits are unavailable, crushed hard caramel candies or butterscotch chips can provide a similar effect.
