Ingredients You’ll Need

• 1 large egg – Acts as the binder for the crust layer.

Optional Add-ins:

Step-by-Step Instructions

1. Preheat oven and prepare pan:
   • Preheat oven to 350°F (175°C).
   • Grease a 9x13-inch baking dish or line it with parchment paper for easy cleanup.
2. Mix the base:
   • In a large bowl, combine the cake mix, melted butter, and egg.
   • Stir with a wooden spoon or spatula until a thick, cohesive dough forms.
3. Press into pan:
   • Press the dough evenly into the bottom of the prepared baking dish, smoothing it out with your hands or the back of a spoon.
4. Add toppings:
   • Evenly sprinkle the toffee bits across the top of the dough.
   • If using chocolate chips, scatter them across the surface.
   • Add nuts or coconut now, if desired.
5. Drizzle and bake:
   • Slowly drizzle the sweetened condensed milk evenly over the entire top.
   • Bake for 25–28 minutes, or until the edges are golden and bubbling and the center is just set.
6. Cool and cut:
   • Let the bars cool completely in the pan on a wire rack to firm up.
   • Chill in the fridge for 30 minutes for even cleaner slices.
   • Cut into 16 squares or smaller bites for serving.

Serving and Storage Tips

• Serve chilled or at room temperature depending on your texture preference—chilled for a firmer bite, room temp for gooeyness.
• Top with whipped cream or a scoop of vanilla or caramel ice cream to elevate your dessert.
• Perfect for lunchboxes – wrap in parchment for an easy snack.
• Storage: Store in an airtight container at room temperature for up to 4 days.
• Freeze: Stack with parchment between layers in a freezer-safe container for up to 2 months.
• To thaw: Let them come to room temperature naturally or microwave for 10 seconds.

Helpful Notes

• Customize your flavors: Try using a chocolate, butter pecan, or even red velvet cake mix for variety.
• Dairy-free options: Use plant-based butter and coconut condensed milk to make it dairy-free.
• Neat slices: Use a sharp knife and wipe clean between cuts for bakery-style bars.
• Presentation tip: Dust lightly with powdered sugar or drizzle with extra melted chocolate.
• Bake evenly: Rotate your pan halfway through the baking time for an even golden crust.

Frequently Asked Questions

1. Can I use a different cake mix flavor?
   Yes! Chocolate, spice, red velvet, or butter pecan cake mix all work beautifully.
2. Do I have to use chocolate chips?
   Not at all. You can skip them or swap in butterscotch, white chocolate, or peanut butter chips.
3. Can I double the recipe?
   Definitely. Use a larger baking dish or two pans, and add 5–7 minutes to the baking time.
4. What kind of toffee bits should I buy?
   Look for Heath brand toffee bits in the baking aisle. You can also chop up Skor or other toffee bars.
5. Why sweetened condensed milk?
   It caramelizes as it bakes, creating a gooey, almost fudge-like topping that binds everything together.
6. How can I make this gluten-free?
   Use a gluten-free yellow cake mix and double-check that your toppings are gluten-free too.
