Maple Walnut Blondies are perfectly chewy and studded with walnuts for the ultimate fall treat.

maple walnut blondies

I live with the Ebenezer Scrooge of desserts.

Boyfriend does not particularly like sweets. In fact, my baking escapades usually result in him crinkling his nose at me suspiciously. Rarely do they result in him eating whatever I have made.

He may as well be parading around saying, “Bah humbug.”

As a baker, this can be more than a little annoying, particularly when I need a taste-tester. As an eater…hey, more for me.


In light of this situation, my friend Cindy has become my primary dessert taste-tester. Nevermind the fact that she is a personal trainer, girl can taste-test sweets like none other.

Recently, she asked me to come up with a recipe for Maple Walnut Blondies, inspired by the seasonal ones at Trader Joe’s. Since she so willingly tries everything I bring her, I figured that the least I could do was provide her with a recipe for Maple Walnut Blondies so that she could make them even after they are “out of season” at TJ’s.


It took me about three tries to get this one right, but in this case, I’d say that third time’s a charm.

These blondies are perfectly chewy, mapley, and studded with walnuts. They’re my favorite fall flavors, jam-packed into one perfect bar cookie.

Even though I shared half the batch with Cindy, I had no problem putting away the other half of these by myself, no help required.

Bah humbug indeed.

Maple Walnut Blondies

Maple Walnut Blondies

Yield: 12 blondies
Prep Time: 10 minutes
Cook Time: 35 minutes
Total Time: 45 minutes

Maple Walnut Blondies are perfectly chewy and studded with walnuts for the ultimate fall treat.


  • 1/2 cup rolled oats
  • 6 tablespoons butter, melted
  • 3/4 cup brown sugar
  • 1/2 cup maple syrup
  • 1 teaspoon vanilla
  • 1 large egg
  • 1 generous pinch of salt
  • 1 cup flour
  • 1 c chopped walnuts


  1. Preheat oven to 350 degrees. Grease an 8x8-inch pan and line with parchment paper. Set aside.
  2. Place the oats in a food processor and pulse until coarsely ground. Set aside.
  3. In a large bowl, whisk together the butter and brown sugar until slightly lightened in color. Add in the syrup, egg, and vanilla, and whisk until thoroughly combined.
  4. Using a spatula, stir in the ground oats, flour, and salt until just combined. Fold in the walnuts. Pour batter into the prepared pan, spreading evenly.
  5. Bake for 30-35 minutes, until the edges are golden and the center is set. (I tend to err on the side of under-baked with blondies, as I feel people prefer those to an over-baked blondie.)
  6. Allow to cool in the pan, then use the parchment paper to lift the blondies out the pan. Cut into pieces and serve. Store in an airtight container for up to 4 days.

  1. Awwww what a sweet treat for your friend!!! Michael used to crinkle his nose at my desserts (unless they were like ice cream or strawberry pie) but I’ve-mostly-converted him 😛

  2. UGH these things look like they’re SO worth the triple effort! When a baking recipe doesn’t work out for me the first time, I tend to just throw in the towel, so nice work sticking to it! Boyfriend may not be huge into sweets, but a little birdy told me he can grill up a mean piece of meat, and that’s worth its weight in gold! 🙂 I want a stack of these at arms-reach at all times!

  3. You can borrow Mike for a week or so to be your taste tester. I am sure with his cookie monster status he would gladly comply. Plus, we are just about to run out of Oreos so he will be so hungry for cooooookkkies! But for real this blondie looks to die for. I am new to the whole blondie thing but I seriously love them more than brownies!

  4. I just finished making these. Probably should have let them cool a bit more, but we were hungry. Three of them are already in our tummies. I’m guessing by the end of tomorrow, there might not be any left at all. 🙂 You know, the family is going to go between horror and delight at the news that he isn’t much on sweets–horror that someone exists like that and delight that there is more for them.

    1. I agree! The TJ’s version uses “maple flavoring”. Um, no. Guess how else you can get maple flavor? Um…duh. Maple syrup. (And that’s really how the convo in my head went with the TJ’s ingredients list.)

  5. Awwwwww! SSSS…I am beyond honored to be mentioned on your blog!
    I can not wait to make/bake my ultimate favorite! I thank you immensely for deconstructing & reconstructing the beloved TJ’s maple walnut blondie brownie! I am forever grateful to you as I can now enjoy them 365 days a year! Luv being your taster, thank you boyfriend, Lol!

  6. You just saved me a lot of money in gas because I love these too, but our nearest TJ’s is almost an hour away! I’m lucky if I get one of whatever I bake. I take something out of the oven, turn my back, and *poof* it’s gone. I may have to bake these in secret and taste test them all myself. 🙂

  7. What IS it with men who have to be harassed to eat dessert?? You’d think I was giving Ben Robitussin, the way he acts about my requests that he try my desserts. Your friend Cindy is one lucky lady, and I am pinning these maple bars of wonder to bake ASAP. If Ben won’t eat them…more for me! Mwahahahaha.

  8. Heeeelarious. Ebenezer Scrooge of desserts. I don’t understand people that don’t like desserts/sweet things. I wish I was one of them though, a bit less sugar would do me good! This walnut and maple brownie recipe looks absolutely perfect though. Stunning is the word. I’d down a whole batch by myself, I’m certain! xx

  9. Delicious recipe!! Thank you so much!

    Living in Québec, and this being the time just before the maple season, there was a huge sale of last year’s maple syrup this week. So I bought a ton of it, and used some to make maple sugar (surprisingly simple : and used it instead of the brown sugar called for in your recipe. Holy maple!!! For good measure I topped the blondies with maple butter… Triple maple madness!!!

    But definitely could not have achieved such delicious results without your perfect recipe proportions! The texture is peeeeeerfect, and the oats add a subtle nuttiness that complement the walnuts beautifully. Thank you very much for sharing!

    Cheers from Montréal!



  10. I was just at TJ’s looking for these. My husband was given a package of them, ate them and asked for more. Alas, they are ‘seasonal’ and none in stock ’til next ‘season’. So I hunted online and Lo & Behold! Here you are with a great recipe for me to try. I’ll let you know how he likes them.
    Also, I’m not the type to figure out a recipe based on the back of a package. So I’m grateful for your hard work.
    Thank you!

  11. Back for another batch! After all, it’s maple syrup season in Québec! Will try to make them gluten-free for my brother-in-law… Hope they turn out well…

    Thanks again for the great recipe, I am already salivating at the thought of them…

    Bons baisers de Montréal!


      1. Hi there! The GF version was perfect! I wasn’t to worried as most brownie/blondie-type cakes require little flour to start with and tend to be denser regardless.

        Instead of the 1 cup of wheat flour, I used 1/2 cup processed oatmeal (on top of the 1/2 cup already used in the recipe), 1/4 rice flour and 1/4 almond meal. I added 1 tbsp. xantham gum (a standard GF flour mix additive which mimics gluten and helps things bind together) as well as a heaping tsp. of baking powder, which helps counteract the tendency for GF flour mixes to “pack tightly” and yield a denser texture.

        The oatmeal taste was stronger, which no one minded, as its nuttiness complemented the walnuts well.

        And as before, I used maple sugar instead of brown sugar, and topped the blondies with maple butter, which makes a beautiful and intensely mapley frosting. I also sprinkled a bit of fleur de sel to offset the sweetness.

        Thank again for the recipe, I couldn’t have achieved such great results without your initial hard work. I appreciate your dedication to precision and your very inspiring blog!



        PS : If you want to see a picture of the blondies, let me know how I can send it to you. Or look me up on Facebook, where I posted it last Sunday. 🙂

      2. This is just the best comment. Thank you so much for sharing your GF method- that’s so helpful for others! And even for myself, as I have some GF friends who would love these. I would love to see pics- you can email me at if I don’t find your profile first. 🙂

  12. Hi Stephie! You’re being featured this week on the weekend social for most viewed recipe this week! Come back by and link up and congrats. This is absolutely beautiful!

  13. I just found this recipe and gave it a try. Due to acid reflux, instead of butter I used butter substitute Earth Balance. They came out GREAT. Thank you so much for putting in the time and effort to perfect this recipe. It’s a keeper at our house.

  14. Hi,
    I know I am late to this blondie party, but I have a question.
    If I use oat flour instead of grinding oats, how much oat flour should I use?
    Thanks for the recipe!

  15. I will eat just about anything that has maple and walnuts in it…fudge, sundaes, cake, pie, and blondies. Thanks so much for the recipe.

  16. I’m going to try this with instant oats since I have a lot that I don’t usually like eating, but if you are already grind the oats, it seems it’ll work? I’m so happy I found this because these blondies from TJ’s look amazing but I love to bake so I usually don’t let myself buy too many baked goods at the store!

  17. I love maple anything and was looking for a new recipe to make today to celebrate Maine Maple Sunday. I got lucky when I happened upon your blog. Oh my… maple, walnuts, oatmeal, brown sugar? Yes please! Thank you so much for the recipe. These blondies are the best ever! My husband and I are trying to control ourselves and not eat the whole pan in one sitting. 🙂

  18. My first attempt at maple walnut blondies was a King Arthur Flour recipe. They usually have great recipes, but their recipe was dry and more cake like than chewy. They shattered when I tried to cut them, too. So I googled, and your recipe came up 3rd one down the list. This recipe is just perfection! I think the oats probably make it moist but chewy. The only thing I changed is using 3/4 cup of walnuts instead of 1 cup. Tried to cut calories, but still wound up at 118 calories per ounce. But so delicious, and I had no trouble cutting them into neat little squares.

    I don’t know if you do your own photography, but it is great, too. Your blondies also looked much better than any others I’ve seen. This one is a keeper!

  19. Sigh. Being a baker with a husband/boyfriend who isn’t into desserts… I totally get you, and it’s ridiculous. These look awesome though, can’t wait to try!
