directions

I preheat the oven to 350°F (175°C) and grease a 9x13-inch baking pan or line it with parchment paper.
In a bowl, I whisk together the flour, baking soda, and salt.
In another large bowl, I beat the softened butter with brown sugar and granulated sugar until light and fluffy.
I add the eggs one at a time, beating well after each, then mix in the vanilla extract.
Gradually, I add the dry ingredients into the wet mixture and stir until combined.
I fold in the butterscotch chips and toffee bits evenly.
I spread the dough into the prepared pan and smooth the top.
I bake for about 25–30 minutes, or until the top is golden and a toothpick inserted in the center comes out clean.
I let the bars cool completely before slicing into squares.

Servings and timing

This recipe makes approximately 24 bars. It takes about 15 minutes to prepare and 25–30 minutes to bake. I usually let them cool for at least 30 minutes before slicing and serving.

Variations

I sometimes swap out the butterscotch chips for white chocolate chips if I want a creamier sweetness. For a nuttier flavor, I mix in chopped pecans or walnuts. If I’m in the mood for more chocolate, mini chocolate chips work great in combination with the toffee bits.

storage/reheating

I store these bars in an airtight container at room temperature for up to 5 days. If I want to keep them longer, I freeze them in a single layer wrapped in plastic wrap and then in foil or a freezer bag. To reheat, I just pop one into the microwave for 10–15 seconds for that fresh-baked texture.

FAQs

How do I keep the cookie bars from getting too dry?

I make sure not to overbake them. As soon as the top is golden and a toothpick comes out clean, I take them out of the oven.

Can I make these bars gluten-free?

Yes, I use a 1:1 gluten-free flour blend in place of the all-purpose flour, and it works just fine.

What kind of toffee bits should I use?

I prefer using pre-packaged toffee bits like Heath bits, either plain or with chocolate, depending on the flavor I want.

Can I make these bars ahead of time?

Absolutely. I often bake them a day in advance and keep them covered at room temperature. The flavors develop even more overnight.

Do I need to chill the dough before baking?

No need. I spread the dough straight into the pan and bake immediately, which keeps this recipe quick and easy.

Conclusion

Butterscotch Toffee Cookie Bars are a sweet, chewy treat that never fails to impress. I love the rich flavor combination and the ease of preparing them. Whether I’m baking for a crowd or indulging in a cozy dessert at home, these bars always bring joy.
