This recipe for Easy Toffee Bars feature a dense, buttery, cake mix base, a smooth, rich chocolate layer, and are topped with small bits of Heath toffee! A SIMPLE DESSERT BAR RECIPE If you need a dessert bar that’s ready in less than 30 minutes that everyone will love, then these Easy Toffee Bars are what you have been looking for. I honestly haven’t found anyone yet that doesn’t love these! This is a little different from your usually toffee treats that use saltine crackers (like Christmas Crack) or graham crackers (Graham Cracker Toffee) as a base. This has a super firm cake layer holding it all together. Plus, this makes quite a few so you can freeze some for later or take this to a party or potluck and it will be enough to serve everyone! FREQUENTLY ASKED QUESTIONS:  Is this salty since we are adding salt and using salted butter? Salted butter actually doesn’t have much salt in it (¼ teaspoon), so we’re adding a bit more salt here to cut the overall sweetness. It does not taste the least bit salty at all. Having said that, you can use all unsalted butter if that’s what you prefer. Where can I find Heath Toffee bits? The Heath Toffee Bits can be found by the chocolate chips in the grocery store. If you need to see the packaging, check out this package of Heath Toffee Bits. Can I make these with a cracker base instead? Yes, you can. I would suggest trying my Christmas Crack Cracker Toffee or my Graham Cracker Toffee recipes instead. Can I use a different cake mix? Yes, as mentioned in the ingredient section, you can swap the white cake mix out for yellow cake mix. This will change the color of the base layer, but it would still be delish. Additionally, you could use a spice mix cake for even more flavor or you could try a chocolate cake mix for any chocolate lovers out there. A butter cake mix could be used that would give it an even more of a buttery flavor, bringing even more shortbread undertones to the flavor profile. Can I add anything to these bars? Yup, try adding chopped nuts, chocolate chips or toffee pieces to the cake batter mixture. Can I use a different topping? Instead of the dark chocolate or semi sweet chocolate chip layer, you can use any type of chocolate, like white chocolate, peanut butter chips or butterscotch chips, or even a combination of them for a fun swirled effect. Can I swap out the toffee pieces? These are the stars of this Toffee Bars, but you can change it up a bit. Try using toasted nuts, sprinkles or chopped candies in place of the Heath Toffee bits.  How to store leftover bars? Keep leftover Toffee Bars in an airtight bag or container at room temperature for up to 3-4 days. You can keep them in the freezer for up to 2 months in a freezer safe container or bag. Thaw them overnight in the refrigerator or leave them out on the counter for several hours. I don’t suggest attempting to reheat them because you’ll change the texture and the taste of the treats. INGREDIENTS NEEDED: (SEE RECIPE CARD BELOW FOR THE FULL RECIPE) white cake mix– if you don’t have white cake mix, you can use a Yellow Cake Mix or vanilla cake mix but the base layer will just have a slightly different color than what you see here. all-purpose flour – you do not want to overmeasure the flour or these will turn out too dirty and crumbly. A lot of people tend to dip their measuring cup into the flour bag or container and scoop it up. You will end up with WAY TOO MUCH flour if you measure flour that way. The best way to do it (if you don’t have a kitchen scale) is to take a spoon and scoop the flour into your measuring cup. Do not pack it down. Once the measuring cup is full take the flat end of a butter knife and scoop off any extra. This will get you the most accurate measure of flour without weighing it. dark brown sugar– I like the deep molasses flavor that the dark brown sugar brings to this particular recipe, but you can absolutely switch to light brown sugar if that is all you have on hand.  salt salted butter– you could use unsalted butter and just add an extra ⅛ teaspoon of salt to the recipe if needed. large egg dark chocolate chips– You can swap these out for semi-sweet or milk chocolate chips if you want to make a sweeter topping.  toffee pieces– Heath toffee bits are a popular brand and that’s what I used. But, you can use any brand, or swap these bits out for toasted walnuts or pecans if you prefer a crunchy topping. If you can not find the Heath toffee bits, you can chop up a Heath bar. HOW TO MAKE EASY TOFFEE BARS: Preheat the oven to 350F degrees. Spray a half sheet (18×13-inch) baking pan with nonstick spray (I like the kind with flour in it) or line with parchment paper. In a large bowl, mix together the white cake mix, flour, dark brown sugar and salt until combined. This can also be done in a stand mixer or with an electric hand mixer. Add in the salted butter and egg and mix until a crumbly dough forms. Press the mixture into the prepared pan in an even layer. You may find it helpful to use a rolling pin (lightly coated in flour so it doesn’t stick) to help flatten it. Bake (on the middle rack) for 14-16 minutes or until golden brown.  Remove from the oven and immediately sprinkle on the dark chocolate chips in an even layer. You want them to be able to melt from the heat. Allow the chocolate to set for about 4-5 minutes then spread around the chocolate until smooth (this should be easy as the chocolate chips should be soft and melted by this point). Evenly sprinkle the toffee pieces on top then allow the bars to cool completely. Cut into squares and enjoy!

Notes Please refer to my FAQ’s (Frequently Asked Questions) and ingredient list above for other substitutions or for the answers to the most common questions. It is important you do not overmeasure the flour or the base will come out too dry and won’t stick together. See my ingredient list in the post above for how to properly measure flour so that doesn’t happen.  NutritionCalories: 209kcal | Carbohydrates: 28g | Protein: 2g | Fat: 10g | Sodium: 172mg | Fiber: 1g | Sugar: 16g
