Ingredients You'll Need
- 1 box yellow cake mix (15.25 oz) - Make sure to use a good quality brand for the best flavor.
- ½ cup unsalted butter, melted - This adds richness; feel free to use salted butter if that's what you have.
- 1 large egg - Room temperature eggs mix better, so let it sit out for a bit if it's cold.
- 1 cup sweetened condensed milk - This gives the bars that creamy texture; don't substitute with evaporated milk!
- 1 cup semi-sweet chocolate chips - I personally love Ghirardelli or Nestlé; they melt beautifully.
- 1 cup toffee bits (such as Heath Bits) - These add that delightful crunch; you can also chop up toffee bars if you can't find bits.
Step-by-Step Instructions
Preheat the Oven
- First things first, preheat your oven to 350°F (175°C). This is crucial for getting those bars baked to perfection.
- While the oven is heating up, grab your baking pan (a 9x13 inch pan works great) and lightly grease it with butter or cooking spray to prevent sticking.
Make the Base
- In a mixing bowl, combine the yellow cake mix, melted butter, and large egg. I like to use a spatula or wooden spoon to mix it all together.
- Mix until everything is well combined and you don't see any dry cake mix. It should be a thick batter, and don't worry if it looks a little different than other cake batters; that's totally normal!
Press the Mixture
- Now, take that delicious mixture and press it evenly into the bottom of the prepared baking pan. It might feel a bit sticky, but just use your fingers or the back of a measuring cup to flatten it out.
- Make sure it's evenly spread, as this will be the base for your toffee bars.
Add the Toppings
- Once your base is ready, pour the sweetened condensed milk evenly over the top. This is where the magic happens!
- Next, sprinkle the semi-sweet chocolate chips and toffee bits generously over the condensed milk. Don't be shy; make sure they cover the entire surface for those luscious bites of flavor.
Bake the Bars
- Pop the baking pan into the preheated oven and bake for about 25 minutes. You'll know they're done when the top is golden brown and the edges look slightly crispy.
- Keep an eye on them towards the end of the baking time - ovens can vary, and you don't want them to overbake!
Cool and Cut
- Once baked, remove the pan from the oven and let the bars cool in the pan for at least 10-15 minutes. This helps them set up a bit more.
- After they've cooled, run a knife around the edges to loosen them, then cut into squares or bars as you prefer. They're perfect for sharing (or not!).
Variations
- For a fun twist, try adding a teaspoon of cinnamon for a warm, spiced flavor.
- Substitute the yellow cake mix with chocolate or spice cake mix for a different base.
- Make them gluten-free by using a gluten-free cake mix.
- Add chopped nuts, like pecans or walnuts, for extra crunch.
- For a seasonal touch, incorporate pumpkin puree and spices in the base during fall.
Serving and Storage Tips
Serving
These Cake Mix Toffee Bars are best served warm, perhaps with a scoop of vanilla ice cream on the side for a decadent treat. You can also drizzle some chocolate sauce on top or sprinkle a pinch of sea salt for added flavor. They make a delightful dessert for gatherings or just a cozy night in!
Storage
To keep your bars fresh, store them in an airtight container at room temperature for up to five days. If you want to keep them longer, you can freeze them for up to three months. Just make sure to wrap them tightly in plastic wrap before placing them in a freezer bag!
Helpful Notes
- If you want a richer flavor, try using browned butter instead of regular melted butter.
- Feel free to substitute the semi-sweet chocolate chips with dark chocolate or milk chocolate for a different taste experience.
- For those with nut allergies, just skip the nuts; these bars are still delicious without them!
- Consider adding a splash of vanilla extract to the base for an extra layer of flavor.
- These bars can be made dairy-free by using dairy-free chocolate chips and a dairy-free cake mix.
