I had to get these Fudge and Toffee Filled Chocolate Chip Bars out of the house ASAP. As I trimmed the edges of these decadent bars before taking photos, I sampled. And then sampled some more.

It was the bit of crunch from the Heath bar chunks that made these so irresistible. Well, that and the huge fudgy center layer. I had to stop before I slipped into a glucose induce coma! I took these treats up to Michigan to share with some childhood friends. There were rave reviews.

Beware, these are rich. A thin layer of chocolate chip cookie dough is topped with a combination of melted chocolate chips and sweetened condensed milk. Next comes the Heath bar chunks followed by dollops of more chocolate chip cookie dough.

Don’t even think about the calories. And don’t leave yourself alone with them either!!! If you like rich fudge or toffee, then these marvelous Fudge and Toffee Filled Chocolate Chip Bars  will be right up your alley.

  • 1 egg
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt

Fudge layer:

  • 1 can (14 ounces) sweetened condensed milk (14 ounces)
  • 12 ounces milk chocolate chips, 2 cups
  • 4 ounces fun size Heath bars, cut into chunks


  1. Preheat oven to 350º.
  2. Line an 8×8 baking dish with nonstick foil (or use regular foil and spray with cooking spray).
  3. Make cookie dough by creaming butter and sugar, then mixing in the egg. Mix in flour, salt, and baking soda, then chocolate chips.

He always asks for something different and I think this is the perfect balance of something different for him but still chocolate chip cookie goodness for me:) AWESOME

  17. Yum, Liz! Alex will love this recipe πŸ™‚

  18. These do look rich!!! Sometime wish we could make single servings to prevent us from eating the whole thing…

  19. If only we could get the same rich flavors and textures in sugar-free! Sigh. In the meantime, glad to have the recipe – and friends to share your yummy bars =)

  20. I wish I could eat all of this in one go my friend πŸ˜€


  21. Wow! These are the most amazing bars ever! They look like they should be in a very gourmet little bakery! You’re really speaking my name Lizzie with the chocolate and toffee!

  31. I love fudge but these look way better than your average fudge. I just saved this recipe and without question will be making these soon. They look so nice and dense and fudgie! YUM!!!

  32. I need a board on Pinterest called “How many recipes from Liz before I gain 30 pounds!”

    These look amazing once again!!

  33. Oh yea – I would definitely find myself having to ask the husband to hide these or give them away. Anything with toffee is irresistible for me and the combination of toffee, fudge and cookie – well – just shoot me now. πŸ™‚

  34. O.M.Greatness!!! I would have to get these out fast too! Toffee just makes everything better.

  35. –Because of you,

  36. You make the BEST sweets, Liz. These look irresistible!

  37. Wow Liz, these bars look like the ultimate decadent treat fit for a queen! Oh my and that filling looks so insanely rich and irresistible! Your bars always look magnificent and picture perfect as always and I definitely couldn’t be trusted alone with these either:)

  38. You’ve convinced me. I must make these bars!

  39. My, my…no wonder you did not want to be left alone with these beauties. I would not trust myself to be alone with these either!

  40. These sound incredible. You’ve always got something so tempting on here!

  41. Yes, these babies would have to leave or else I’d lose myself in them!

  42. I’m afraid I “sampled” everything before I shared with others. I can TOTALLY see you struggled to get these out of your house. It’s IMPOSSIBLE! πŸ™‚ I wish I can even have a slightest corner of your bars…

  43. These look positively dangerous…and I mean that in the most delicious way possible!! πŸ™‚

  44. These are incredibly dangerous. I can’t get over that insanely thick rich fudgy filling! Can I move in with you? I swear I’ll make myself useful. I’ll do anything so that I can eat everything you make!

  45. I loved that you caught yourself tasting these too much…. I do that too. πŸ™‚ Sometimes I wonder if I will have enough for my photos. πŸ™‚ These sure look decadent and beautiful. πŸ™‚

  46. Good grief – I would break my diet for those!

  47. Have these in the oven right now. It’s my Grandmother’s birthday and I still haven’t figured out how I will get them baked, packaged, and to her without eating them all. Thanks for sharing!

  48. OMG, these look amazing! I could never eat them ( too much sugar) but I can sure appreciate them.

  49. You make some serious bars, but this one has got to be one of the most tempting ever Liz! Seriously. IsnΒ΄t fudge the best thing when done right? CanΒ΄t wait to share these.

  50. Lizzy,
    These bars look incredible. I have to make them soon.

  51. You do make the best desserts, Liz, absolutely the best chocolatey desserts, too. Whenever I need a special treat, or just inspiration, I nose around here!

  52. I just found your site via Manu’s Menu, and I am so glad I did! These would not be safe in my house. Who am I kidding? No sweets are safe in my house!

  53. Oh, goodness. Those are beautiful. Keep them far, far away from me! Hahahaha

  54. HI, everything looks scrumptious πŸ™‚ What is a fun size health bar?

    • They are small, two bite sized Heath bars (chocolate covered toffee candy). Each weighs about 1/4 oz. If you have access to any chocolate covered English toffee candy, it would work fine.

  55. these are a delicious addition to my cookie and candy tray!

  56. You are correct. These are so decadent! We loved them!

  57. This taste every kind of amazing!

  58. These are my new favorite treat! So good.

  59. I loved how easy this is to make! Really good!
