Fudgy Toffee Cookie Bars

Why You’ll Love This Recipe

If you love bar cookies as much as I do, then these Fudgy Toffee Cookie Bars are a must make!

With three delicious layers, including toffee, graham crackers, and plenty of chocolate, there’s something for everyone in this decadent triple layer bar cookies.

Unless you don’t like chocolate. Or cookies. Which is kind of crazy, but I know these people exist. For them, I recommend my equally amazing Sugar Cookie Bars. Actually, even if you love chocolate, you should try the Sugar Cookie Bars too.

One of my favorite things about these bars is the fact that they are so easy to make, even with the three layers. That’s the beauty of the bar cookie. It all goes into the pan at once, which saves so much time and effort.

Fudgy Toffee Cookie Bars

I like to use milk chocolate chips in the top layer of these bars, to contrast with the darker chocolate fudge layer. But you can absolutely go with semi-sweet or even dark chips if you like.

Of course, what really makes these bars stand out is the additional of the toffee bits. They add a bit of crunch and a caramel-like flavor that really gives these cookie bars a unique flavor.

And I suppose it goes without saying that one of these bars is the perfect thing to go with a tall glass of cold milk. You really can’t go wrong with that as an after-school or late night snack.

Like I said, these Fudgy Toffee Cookie Bars are a must try. They’re a favorite at my house and I think they’ll be a favorite at your house too.

Be sure to save this recipe to your favorite Pinterest board for later.

    These are really yummy! My only suggestion is that you wait a minimum of 3 to 4 hours for them to cool before cutting them. 90 minutes after taking them out of the oven, I tried to cut them. They were falling apart and just looked like raw cookie dough. Because of that, I missed the boat on taking treats to my gathering. Once I got home, I was just going to put them in a container for the family to munch on and was surprised when they cut beautifully and were quite delicious. 🙂
