Decadent, chewy blondies made with browned butter and maple syrup and topped with a crisp walnut crumble.
I like to spend my autumns holed up in the kitchen, tapping my foot to the rhythm of my KitchenAid, warming the kitchen to a comfortable 350 degrees, and burying myself in baked goods.
Fall weather is baking weather.
Technically, all weather is baking weather in my house, but I don’t know if I ever enjoy it as much as I do during the Fall.
During the summertime, I feel mostly limited to no-bake recipes and fruity desserts, but right now I don’t feel so bad about warming up the kitchen with the oven (especially since Zach doesn’t believe the heat should be turned on until January!), and fall flavors are so much fun to bake with.
I’ve captured some of the best flavors of fall here: browned butter, brown sugar & walnut crumbles, and a hint of maple, all topped off with vanilla bean ice cream and homemade salted caramel sauce.
Let’s talk about browned butter for a second. Have you ever made it before? I’ve used it both in my brown butter chocolate chip cookies and my pistachio cake, but haven’t ever used it in blondies (…or anything else, for that matter) before.
Browned butter is made by heating butter in a saucepan until most of the water cooks out of it (in a snappy little orchestra of pops and sizzles) and it begins to brown. It takes only five minutes or so, and fills your whole kitchen with a buttery, nutty aroma that I have no idea why Yankee Candle hasn’t yet incorporated into their collection (I would buy so many brown butter scented candles!).
The browned butter helps make these blondies nice, soft, and chewy (and, of course, rich with a next-level depth of buttery flavor), but that’s not the only factor at play. Brown sugar and maple syrup also are key factors in keeping things nice and soft. The maple syrup is subtle (and you can definitely use maple-flavored pancake syrup, if you don’t want to spring for the pure stuff), but it helps with the chewiness and adds to the flavor.
I topped everything off with a walnut crumble (the same one I used in my Dutch apple pie, in case you were trying to remember why it looked so familiar) which adds a nice crunch in contrast to the soft chewiness of the blondie.
Then, if you’re feeling extra indulgent, warm your blondie before enjoying (these taste good at room temperature, sure, but please do yourself a favor and try them warm!), top it off with vanilla ice cream, and drizzle with some homemade salted caramel sauce.
Enjoy!

Okay, I am just starting to make it, but I have to say, I love that you mentioned measurements in the instructions as well. Scrolling up and down your phone with flour in your hands is not fun. I feel like half the baking time gets spent scrolling through the page otherwise. So thank you, I really appreciate that I can just look at the instructions without having to scroll. 🙂
We are so happy it is helpful, Alisha! We love it too 🥰
I totally agree!!!! Thank you for including the measurements in the actual instructions!
The taste of these are pretty amazing. The one problem for me is the batter was so thick I cooked it for 13 extra minutes and even still should’ve cooked it longer.
Hi Colleen! Wow that’s a long time, did you use a glass pan by chance? I’m glad you still enjoyed them!
Hi Sam-I increased the recipe by 50% and used a 9 x 13 pan. It was glass. Something simple like that can change it by so much I guess!
