Gooey and delicious Toffee Chocolate Chip Cookie Bars with a chewy crust and caramel-like filling. This easy dessert recipe is perfect for a crowd, and I love that you can make it in advance.
These dessert bars are a guaranteed crowd pleaser; I get asked for the recipe every time! Some of my other go-to cookie bars include Smore's Cookie Bars, World's Best Peanut Butter Bars, and Oatmeal Chocolate Chip Cookie Bars.

Toffee Chocolate Chip Cookie Bars
There's nothing I love to do more on a relaxing Sunday afternoon than bake a treat with my kids! If you follow me on Instagram you'll see that I often use the hashtag #weekendsareforbaking, because it's so true!
I especially love cookie bars because they take the work of rolling dough and baking multiple batches, out of the equation. Everything is baked right in one pan, and my kids love helping me add the layers to these toffee bars. If you love toffee, don't miss my sticky toffee pudding recipe.
How to Make Toffee Chocolate Chip Cookie Bars:
- Combine flour, salt and brown sugar.
- Cut in the butter with a pastry blender or fork until the mixture is crumbly.
- Add the eggs and chocolate chips.
- Set aside 1 ½ cups of the dough. Press the remaining dough into a 9×13” baking pan lined with parchment paper
- Bake
- Remove from oven and cover with sweetened condensed milk.
- Sprinkle toffee bits on top.
- Dollop the remaining dough over the toffee bits. Sprinkle with remaining chocolate chips and toffee bits.
- Bake for 25-30 more minutes, or till golden brown. Cool completely before serving. I think they taste even better the next day! Cool completely and store, covered, in the fridge.

General Baking Tips
To master baking, there are a few tips that make the difference between average baked goods, and spectacular baked goods.
High Quality Ingredients
Purchasing high quality ingredients is especially important in baking. You have to have high quality butter (not margarine, or any other brand of fake butter–you've got to get the real stuff)! High quality chocolate is also great to have when baking. It may seem trivial, but a good brand of chocolate chips will make a big difference in taste and texture.
Room Temperature Ingredients
My second baking tip is to use room temperature ingredients. Room temperature butter, and room temperature eggs, in particular, are a must! Have you ever noticed the difference between cold and room temperature eggs? Crack one of each open and you'll notice the room temp eggs yolks are bigger and “fluffier” looking.
You can keep those two tips in mind when making these amazing Toffee Chocolate Chip Cookie Bars! Let's be honest, toffee and chocolate is always a winning combination! These dessert bars have that going for them, plus a yummy layer of caramel flavor from the baked sweetened condensed milk.

I’ll make flan.
I love to make cheese cakes for the holiday! I’m going to make one with peppermint!
These look amazing! Can’t wait to try them! And we always buy egg lands, the best!
These look so good! I am a big fan of any treat in bar form and have been wanting to try some sugar cookie bars with leftover Halloween candy. How long would you say it’s best to let eggs sit to get room temperature?
These sound delicious! I may need to make these. We always make rainbow jello for Thanksgiving. Another is scotcheroos. They are a holiday must!
OMG I can’t wait to make these! I already know Jacob will love them too! Unlike some of the desserts I selfishly make only for myself (ahem…pumpkin things.)
This looks so good! I make Christmas muddy buddies every year!
We LOVE homemade hot cocoa! And pumpkin pie! These toffee bars look amazing, too!
WOW! These look incredible! Can’t wait to try them…I may have to make two batches!
We make fudge every year!
