3) Ingredients for Cake Mix Toffee Bars

1 box yellow cake mix: This is the base. It brings structure and that sweet, buttery flavor without needing flour, sugar, or baking powder separately.

1/2 cup packed brown sugar: Brown sugar adds moisture and that deep caramel note that pairs so well with toffee bits.

1/2 cup melted unsalted butter: Butter binds the mix and adds richness. I use unsalted so I can control the salt later.

2 large eggs: These help hold everything together and add a bit of chew to the final bars.

1 bag (8 oz) toffee bits: The star of the show. They melt slightly and give the bars a crunchy, gooey vibe.

1/2 cup chopped pecans (optional): I love the crunch, but you can skip them if nuts aren’t your thing.

4) How to Make Cake Mix Toffee Bars

Step 1. Preheat your oven to 350°F and grease a 9×13-inch baking dish. No parchment needed—just a good spray or swipe of butter.

Step 2. In a large mixing bowl, stir together the cake mix and brown sugar. It may feel dry but hang in there.

Step 3. Add melted butter and eggs. Stir until the mixture is fully combined. It’ll be thick like cookie dough. That’s what we want.

Step 4. Fold in the toffee bits and pecans. The dough gets even better here—chunky and rich with little surprises.

Step 5. Press the dough evenly into the prepared pan. It helps to use your hands—just rinse them and get in there.

Step 6. Bake for 25 to 30 minutes. The edges should be golden and the center set but soft. It firms up as it cools.

Step 7. Let it cool completely before slicing. This step builds patience (and keeps the bars from crumbling).

5) Tips for Making Cake Mix Toffee Bars

If your bars are coming out too dry, try baking them five minutes less next time. Every oven has a personality—some run hot, some are more chill.

Chop the pecans a little smaller if you want a smoother texture, or leave them chunky for more crunch. It’s flexible.

Don’t skip the cooling time. It’s tempting, I know, but the bars cut cleanly and hold their shape so much better when fully cooled.

6) Making Cake Mix Toffee Bars Ahead of Time

I’ve made these a day ahead for potlucks and they actually taste better the next day. The flavors deepen and the texture sets perfectly.

Just bake as usual, cool completely, then cover tightly. I leave them in the baking dish and cover it with foil. They keep well on the counter for a couple of days or in the fridge longer.

If you want to make the dough ahead of time, that works too. Just press it into the pan and refrigerate, covered, until you’re ready to bake.

7) Storing Leftover Cake Mix Toffee Bars

Store leftovers in an airtight container at room temperature for up to 4 days. They never last that long around here, but technically, they can.

If you want to freeze them, cut into squares first. Wrap each bar in plastic wrap and store in a freezer-safe bag. They’ll stay fresh for about a month.

Reheat in the microwave for 10 seconds if you like a little warmth. Or eat them cold. Honestly, they’re good either way.
