Apple Toffee Blondies

Apple Toffee Blondies are buttery blondies with tart apple pieces and sweet toffee bits! It's topped with a brown sugar frosting!

Apple Toffee Blondies are JAM PACKED with sweetness. From the buttery, apple blondies, studded with toffee bits, to the brown sugar frosting, these are always a huge hit!

This recipe as been a classic on my site for so many years. I wanted to give the photos a little spruce up, but I left the recipe EXACTLY the same. Sometimes things are just perfect as-is!

It’s September, which means apple vibes are in full effect. BUT I have to say that I am an apple girl all year long. Certainly they’re in abundance this time of year, but I don’t discriminate when it comes to my sweet treats. That would be wrong.

And the great thing about this recipe is you can make it like I show here…with tart apple pieces and toffee bits inside a buttery blondie, topped with a rich and sweet frosting…OR you can leave out the toffee bits, if that isn’t your thing…or even leave off the frosting!

Personally, I am a frosting girl, but I have made these and dusted them with a little powdered sugar and they were still amazing. The frosting is just an added bonus for those of us with a serious sweet tooth!

  1. I was just about to make your Chocolate Toffee Bars, and now? This deliciousness! I don’t know what to do! Which to make?! But this is a good sign when this is the today’s hardest decision.

  2. Haha, I love the bit about your dream and getting mad at your husband. I sometimes find it difficult to forgive people for things they’ve done in my dreams. They should be more careful about how they behave in my head!

    I don’t even know where to begin on these. They look so good, I’m wondering when I could make them!

  3. These sound delicious and the icing takes these to a whole nother level. I relatively new to your blog and I’m still in awe of your recipes and photos. You’ve created a beautiful spot for your readers to visit and I really enjoy the time I spend here. I hope you have a great day. Blessings…Mary

  4. This is a GREAT one Shel! I don’t know how you come up with these things! This one is going to be a hit…perfect for fall. Now for the list…I can tie a cherry with my tongue. Does this change what you think of me? I saw the housewife thing too. From the dentist’s office. All I could think is that my life would be much improved if I looked like her. I know someone who is Toddler and Tiara’s material, and I shift between wanting to punch her, and thinking about abducting her child. And, um, I bet Kim Kardashian can buy clothes from the Salvation Army and still look drop dead gorgeous. That’s my two cents for the week.

  5. Such a LOVELY and oh so YUMMY looking dessert with fruit in it! I’ve been excited to start baking with apples as Fall has gotten into full swing here in Southern NH….your recipe is just what I’ve been looking for! Many, many thanks! 🙂

  6. I have this weird feeling that I’ve made these before…it goes really well with your weird morning. I saw a commercial for an episode of the Kardashians where they were talking about their clothing line. Apparently there is “something for everyone”. Unless you don’t like leopard.

  7. OMG seriously…you almost make me piddle in my pants. I hate when I have those kinds of dreams when I wake up pissed at the world! I have actually woken up and gave my sleeping husband a huge punch on the arm because he was “cheating” on me with Susan Boyle!
    And “Like” I cant believe the Kardashians are selling at Sears. I mean, they could have made a deal with JCPennys at least!
    But I do love your yummy dessert. That makes up for my husband cheating on me with Susan Boyle

  8. Brown sugar frosting?? Now that sounds amazing to me! I sure hope your day got a lot better after posting this! I mean if you ate more of these bars, I’m sure that would help:-)

  9. A. Can’t tie a cherry with my tongue.
    B. Don’t watch her show.
    C. Don’t watch that show.
    D. Glad he didn’t miss the bus
    E. Don’t watch their show and tired of seeing their faces at my supermarket check-out.
    F. Love this recipe, love that there is fruit in it and that it’s apple and love that it has a brown sugar frosting.

    This post cracks me up. Your husband seems to be very easy going! 🙂
    These look delicious – pinning them for this weekend when I’ve got a hard-working, hungry crew of men here harvesting corn. Gotta love fall!

  11. Ok, I heard about this Kardashians clothing line. It sounds just straight U-G-L-Y, you ain’t got no alibi you ugly, ya ya you ugly. I hope today starts off slightly less bizarre. Maybe you should eat these for breakfast, that’ll get your day headed in the right direction!

  12. Desserts with fruit is the best. Toddlers and Tiaras and leopard-print jumpsuits are train wrecks. I’m glad we have both in the world so everything balances out 🙂 Thanks so much for posting this recipe – it’s perfect for the fall 🙂

  13. Trina

    Looks like a wonderful fall recipe! I’m Gluten Free though…..I’m gonna try and use a GF flour blend. I have to at least try! Right? Wish me luck!

  14. megan

    Made these and they turned out good…the frosting is the BOMB, of course, but my bars did not look soft, gooey or dense like your picture. I will do a few things different next time:
    1) add at LEAST 2 cups of diced apples…one cup was barely noticeable
    2) I would add the whole bag of toffee bits
    3) I would only cook about 22-25 minutes…definitely doesn’t seem to need 30 minutes…

    I also added about a tbsp. of cinnamon and a dash of nutmeg…that gave it a great, warm flavor 🙂 I’ll let you know how the next batch goes 🙂 (and thank you for posting…even with changes, I think it’s a great recipe!)

  15. C Allyn

    First time here…made me chuckle, the story,not the recipe.
    Recipe sounds great and I am trying that this week.
    The dream resonates with me.
    I dream about something, wake up mad and the husband has no idea what happened.
    Poor guy, better bake him a batch of these brownies.

  16. Bettie

    I just finished making these blondies. I must say that I was disappointed because the recipe said to wait 30 minutes for the icing to set up…….I didn’t wait. I took one little corner and WOW!!!!. These are absolutely delicious. Thank you so much for sharing this perfect fall treat. I will wait for the icing to set for my next piece….:-)

      1. Bettie

        My husband has already had two slices since he came home from work. May have to hide them really soon. And he is like you…TOTALLY dislikes fruit in a dessert, but is really enjoying these.

  17. I made these on this rainy, chilly day here in Wisconsin. They’re awesome! I did have to add 10 more minutes to the baking time though, as it was still very jiggly in the center at 30 minutes. They turned out great. I also had more than 1 c. of a huge granny smith apple. They are VERY sweet, thus small squares are being cut. This is a keeper!

  18. traci v.

    these are soooooo delicious and the recipe makes a lot. the only complaint I have…and I can’t believe I’m saying this…is that I found the frosting to be too much, in quantity and sweetness. next time, I’ll halve the amount and just give the bars a think layer. they are so good though and will be added to my favorites!

  19. I made these the other day and the ladies at work loved them! I substituted and toffee bits with pecans and they were so yummy!! I posted the recipe on my blog and linked it back to you 🙂

  20. As soon as I saw this recipe I knew I had to try it! I made these for work a few days ago substituting pecans for toffee bits and they were a massive hit with everyone who tried them!! Thank you 🙂

  21. Sara

    I made these this afternoon, and oh mah goodness. They were absolutely divine. The frosting on top sends the richness factor over the moon and back, so just a little morsel is more than sufficient! Without the frosting, the blondies aren’t extraordinarily sweet. I found that the toffee didn’t seem to add much except more butter (which this has a-plenty). The tart apples are really what sets this recipe apart. Thanks for sharing. I’ll definitely be keeping this recipe around for special occasions in the future!

  22. Joy

    Love the recipe! I used Gluten Free flour and used white Choc, Chips – since I was out of toffee chips. I did alter it and was very happy w/ the results. Thanks.

  23. M

    These were very good but veeeery, very sweet. I personally thought the frosting was overwhelmingly sweet, but my mom told me it was just right and gobbled them up. I guess it’s all about personal preference. Next time I think I would use less frosting and maybe leave out the toffee since it brought a very buttery taste along with the butter already in the recipe. Of course when I mentioned that to my mom she scoffed, so don’t necessarily follow my lead!

  24. These are so yummy! Just don’t be like me and reduce the sugar to 1 1/2 cups or you’ll end up with cake. Not cake-like blondies, but cake. 🙂 But it’s a delicious cake! It could also have something to do with the German flour. I tripled the apples because after tasting the batter, I knew certain people would still whine about the sweetness. So I threw in a bunch of tart apples. Perfect. 🙂 I can’t wait to make this as written! (but hey, it wasn’t my fault… seriously, they’d be all, “Too sweet, too sweet! YOU Americans make everything too sweet!”) Ugh.

      1. I didn’t making the frosting although I wanted to. I made these to ship off to my husband and thought the frosting wouldn’t do so well. But instead of shipping them off, I covered half of it in caramel sauce, plopped the other half on top and now have an amazing cake. Whoospie!

        Zee Germans are going to get granola bars instead. 😀

  25. Tara

    These are very good, but veeeeeerrrrry sweet. I would make them again, but would have to figure out a way to cut the sugar a bit. My teeth were literally aching after I ate one! The flavor is amazing, just too much sugar. Also, I followed the recipe exactly and the middle was undercooked, which made them stick to the pan. I would add 10 more minutes next time. Thanks for sharing!

    1. William

      oh you ladies that are commenting on the fruit that’s in this lovely dessert…..keep in mind there is a total of 5 cups of sugar in this sweet fat daddy!

    1. shelly

      I stored mine at room temperature, but putting them in the fridge wouldn’t hurt. Just allow them to come up to room temperature before serving 🙂

  26. I’ve made these blondies on two occasions this fall. THANK YOU for one of the best recipes I’ve ever seen. These are dangerously delicious. Everyone who has had one has loved them. My boss even called eating one a “religious experience.” Haha! Such is the power of this dessert.

  27. Nancy Crone

    Sounds like my kind of food. But…(there’s always a but, isn’t there?) Where are the pecans. Down here in Texas, it isn’t edible without pecans. Hope you don’t mind if I cheat and put a few (like a couple of cups) chopped pecans in this before baking. And your brown sugar buttercream sounds like something I’d get up in the middle of the night for. Thanks.

  28. Christina

    Made these for a Husker tailgate party. I forgot to add the toffee chips to the batter, so added them on top of the bars before baking. I also added Biscoff cookie butter to the frosting and reduced the amount of butter. My, oh my – these bars are delicious!! Received many compliments and everyone asked for the recipe. Thank You for sharing.

  29. Mary J

    I thought the story was hilarious, but these bars are SUPER sweet, I might try experiementing with less sugar, two cups of brown sugar is staggering.

  30. Jeanne Haley

    I’ve decorated for fall all weekend and then baked these awesome Apple Toffee Blondies this afternoon. They are just delicious. After reading all the replies, I decided to make a half recipe of the icing and they turned out perfect. Too many for hubby and I, so I’ve boxed up some and will gift to friends. I love your Blog and am a follower. Everything I’ve tried is so easy and delicious. Thank You!

  31. Francesca

    First of all, delicious recipe – thank uou very much for sharing Shelly. I’m sure my friends will love these. Please may I ask though, how did you get your frosting so smooth and even? It looks perfect. Any tips? Thank you. I baked these last night, left them to cool whilst I fell asleep to the gorgeous apple aroma running through my house, lol and this morning I have made the frosting and finished the blondies and now my house smells sweet and fall like and I don’t want to leave to go to work! Thank you Shelly 🙂

  32. archana

  33. markus
