It’s hereeee. Yes, I am officially welcoming pumpkin season with open arms. The fall-like weather in Boston the last couple days totally makes it acceptable. Though I’m pretty sure it’s going to be in the 80s on Friday. That’s the thing about this time of year- you never really know what you’re going to get. That’s why I’m continuing to withhold on sweaters, riding boots, cute scarves, and fall coats. I love my sweaters and boots, but let’s be honest, I have PLENTY of time to wear them in Boston and come April, I start to hate them just a little bit. Pumpkin? I only give myself until December to enjoy the orange goodness, so I may as well let myself jump right in. As you’ve probably realized by now, I think about these things way too much.

I mean, I could go ahead and say I was just thinking about you. And the fact that you might want to make some pumpkin treats. And if I wait to post my pumpkin treats, you might not be able to make them. Then again, whoever “you” is seems to already be pinning Christmas recipes to Pinterest out the wazoo, so now I’m starting to feel like I may be late to my ride on the pumpkin train. If I’m to judge by Pinterest, “you” is also a fan of candy corn, which means I need to get on my annual candy corn recipe for the year. From now on, I’m just going to assume that the types of pins on Pinterest must signify the average person. Which means y’all really want to put on your riding boots and get married in a big crock pot full of mac and cheese in a kitchen with a million windows and white granite counters. Oh, and with the perfect abs. And a really, really organized closet. Is that you, perhaps?

Or maybe you just want people to learn how to pin images that link to the original source and for all the spammers to go away. And maybe you want to make gooey Pumpkin Butterscotch Blondies. I can’t send the Pinterest spammers to their doom, but I can help you with the blondies. They’re fall festive, nice and chewy, and super gooey from the marshmallow topping. Everything I could want from my first pumpkin recipe of the year.


I struggled with whether to call this pumpkin cake or blondies because it’s kind of like a cross between the two. The first time I made them, they were super blondie like, but almost too gooey and stiff. So, I tweaked the recipe a bit and these are the results; a super moist baked good that’s a little cake-y and a little fudge-y. With a nice gooey marshmallow topping and lots of extra fun from the butterscotch chips.

This recipe is extremely easy and only consists of making the simple pumpkin blondie batter, baking it, and then topping it with mini marshmallows and buterscotch chips and baking it some more.

And then these pumpkin blondies are yours all yours!

Told ya they were easy.

I’m always good for a blondie and the kick of pumpkin spice really gave these an extra layer of love. Plus, I’m pretty sure the pumpkin puree gave them that extra level of moistness.

You could totally frost these with some sort of cream cheese icing if you desire (I suddenly realized that my marshmallow actually does look a bit like cream cheese frosting!), but I decided to go the marshmallow route because I still have a little bit of s’mores season left in me and I’m giving it a fighting chance.

The butterscotch chips were just a given because, well, they’re blondies. And butterscotch chips belong in blondies. Even pumpkin blondies.

Although perhaps the real question is, “what doesn’t belong in a blondie?”

Maybe candy corn? Candy corn in blondies? At first I thought that might be a little too much, but now my brain is ticking out of control.

I do need to come up with an idea for my annual candy corn recipe, after all. Don’t say I didn’t warn you.

Seriously though, it makes me happy to welcome pumpkin back into my life. I love summer with all my heart, but I’m excited for the snuggly cozy feeling of fall. And pumpkin definitely makes me feel at home. These pumpkin blondies are also perfect to make when you know you most likely won’t be getting into a bathing suit for another 8+ months. They say a little extra padding helps keep out the cold, right? Right??

Have you succumbed to the fall foods yet or are you still holding out?

    It’s so hot in LA!!!! Too hot to do a lot of baking, so we may have to sprinkle fall recipes in a little at a time. There was a soup last week though, so that hit on the fall mood. Can’t wait for it to be cool enough for nighttime baking. Love these blondies. If they’re hard to cut, that just means someone’s going to get an awkwardly large piece. Not that that’s a bad thing!

    I’m with ya on pumpkin season! DC has had a couple uncharacteristically nice days, so it seems like it’s time 🙂

    I actually posted a fall recipe roundup on my blog a couple hours ago and included an older recipe of yours (the apple cider cookies.) I’m thinking I should have waited an hour and stuck these in there too – they look awesome! The marshmallows are such a unique twist!

    i’d say the hardest part of these would be keeping my paws off of them right out of the oven 🙂 love the marshmallows on top!

    ps- I choose the better race photos, there are plenty more where I don’t look so “fresh” 🙂
