The Easiest Halloween Dessert!
Every year I see these candy corn white chocolate M&M’s around Halloween, and don’t do anything about them. But this year I decided do something about them. And by that, I mean bake them into soft, buttery blondies.
When I made the Candy Corn and White Chocolate Softbatch Cookies, many people asked if I had tried the M&Ms Candy Corn White Chocolate Candies, and yes, I sure had.
The Halloween M&M’s blondies are super soft, dense, flat, and moist. I don’t add chemical leaveners such as baking powder or soda to my blondies because I like ‘fudgy’ blondies.
It’s also why I never add leaveners to my brownies. It makes them cakier and while I love cake, I don’t prefer that texture in my blondies or brownies.
While baking, the brown sugar caramelizes with the butter, and you’re left with caramel undertones amidst the buttery, rich dough.
The big white chocolate M&M’s are the perfect complement to the buttery base. Save this leftover Halloween candy blondies recipe for all your leftover candy from Halloween trick-or-treaters (or Easter or birthday party candy!). Chop it up and bake it in. Extra candy makes everything taste better!
What’s in the Halloween M&M’s Blondies?
To make these Halloween M&M’s blondies, you’ll need:
- White Chocolate Candy Corn M&M’s
- Unsalted butter
- Egg
- Light brown sugar
- Pure vanilla extract
- All-purpose flour

How to Make White Chocolate M&M’s Halloween Blondies
Like all my blondies recipes, these Halloween blondies are a cinch to make. Here’s an overview of the process:
- Melt the butter for 1 minute in the microwave. Wait momentarily. Then, add in the egg, brown sugar, and vanilla, and whisk until smooth. Adding the egg too soon will cause it to scramble!
- Add the flour to the wet ingredients, and stir just until smooth. Fold the M&Ms into the mixture.
- Turn the batter into a square baking pan lined with aluminum foil or parchment paper and greased with cooking spray, spreading it out evenly. Sprinkle the remaining M&Ms on top, pressing them down slightly with your finger.
- Bake in a preheated oven until the bars are golden brown and a toothpick inserted into teh center comes out clean or with just a few moist crumbs.
- Allow your blondie cookie bars to cool in the pan for at least 30 minutes before slicing and serving.
Enhance the flavor
If you love a sweet and salty contrast, feel free to add a sprinkle of flakey sea salt as soon as you remove your blondies from the oven.
Recipe FAQs
Of course! I bought the M&M’s at Target, and they’re seasonally available at Target, Wal-Mart, many grocery stores, and Amazon. If you can’t find them in your area, white chocolate chips will duplicate the flavor most closely. Or, use regular M&M’s, Reese’s Pieces, Reese’s peanut butter cups, chopped Milky Ways, Snickers, mini Rolos, or your favorite diced candy bar for tasty candy bar blondies.
If you want to add candy corn, I recommend making my candy corn white chocolate chip blondies instead! Make sure the candy is not touching the bottom of the pan and is well-shielded by batter or it’ll melt and then stick fiercely to the pan. The same principle is discussed in my Candy Corn and White Chocolate Softbatch Cookies post.
You may double this recipe if desired. Just double the ingredients list, and bake the bars in a 9×13-inch pan.
Once cool, leftover blondies will stay fresh in an airtight container at room temperature for up to 1 week.
Yes! You can freeze Halloween blondie bars for up to 6 months. I recommend wrapping each bar in parchment paper and transferring them to a sealable bag to keep them fresh and prevent them from clumping. Thaw them in the fridge overnight or at room temperature when you’re ready to eat.

Candy Corn White Chocolate M&Ms Halloween Blondies
Equipment
- 1 Large, Microwave-Safe Bowl
Ingredients
- ½ cup unsalted butter, 1 stick, melted
- 1 large egg
- 1 cup light brown sugar, packed
- 1 tablespoon vanilla extract
- 1 cup all-purpose flour
- 9.9- ounce bag M&Ms Candy Corn White Chocolate Candies
Instructions
- Preheat oven to 350F. Line an 8-by-8-inch baking pan with aluminum foil, spray with cooking spray; set aside.
- In a large, microwave-safe bowl melt the butter, about 1 minute on high power.
- Wait momentarily before adding the egg so you don’t scramble it. Add the egg, brown sugar, vanilla, and whisk until smooth.
- Add the flour and stir until just combined, don’t overmix.
- Stir in 1 cup M&Ms
- Turn batter out into prepared pan, smoothing the top lightly with a spatula.
- Add remaining M&Ms to top of batter, dispersing them evenly, and pressing them down lightly with your finger.
- Bake for about 23 minutes, or until done. At 23 minutes (shown in photos) they’re very soft and moist; if you like firmer and dryer bars, bake for a few minutes longer. A toothpick inserted in the center should come out clean, or with a few moist crumbs, but no batter.
- Allow bars to cool in pan for at least 30 minutes before slicing and serving.

My mom loves candy corn.. I am going to whip her up a batch of these for sure
Got to track down these M&Ms! Such a perfect fall treat!
I must be the be the biggest candy hoarder. I bought a few bags of these last month and hid them in the baking pantry. Now, you’ve given me the excuse to put them in these yummy bars you created. (Have I mentioned lately how I love that I can trust your recipes?) These are definitely calling my name! Pinned.
Thanks for pinning and thanks for saying you trust my recipes – that is awesome and I appreciate it!
I didn’t think they tasted like candy corn at all either; glad I’m not crazy. I like them, sure, but they aren’t candy corn flavored.
I also thought it was just me losing my mind – glad to hear I’m not alone!
My husband would die over these, he loves candy corn! They are perfect for Fall! I wish I had one right now!
I am dying over those pumpkin OCPies of yours!!
Averie, I’m so glad that you mentioned that these M&Ms aren’t necessarily candy corn flavored. I thought that same very thing! I still loved them and we nearly finished the bag in am embarrassingly short amount of time, they just weren’t what I expected. BUT that being said – they make an amazing accompaniment to blondies! Especially your super buttery, soft blondie base. They look amazing – such a festive dessert for October!
Have you tried the pumpkin M&Ms yet? I believe they are only available at Target. Now those really taste like pumpkin spice!
I thought it was just me losing my mind – glad to hear I’m not alone thinking they don’t really taste like candy corn! Good but they just weren’t what I expected either. They are the perfect baking candy. Sweet, soft, colorful, loved them in the blondies.
And the pumpkin ones – I bought these at Target b/c Target was sold out of the pumpkin ones… Gah! Still need to try those!
Candy corn and white chocolate are two of my sister’s favorite things. I totally need to make these amazing looking blondies for her!
You would get major brownie points I think :)
Woah Averie, these blondies look over the top delicious!
These are so festive! I made blondies with candy corn last year and I have a craving to recreate them.
Oh wow, good to know! Had I had any actual c.c. on hand, I would have tossed it in, too…but was out!
I don’t think I have ever seen those M&M’s or probably my eyes just skipped over them since I am normally eyeing only the chocolate candy. These days I am really trying to branch out and give things like white chocolate a go! Still not a candy corn person, but I bet with the sweet white chocolate I would still like these M&M’s. So I have to try and search for them at target! Gorgeous bars, as always! You get the most perfectly cut squares, I don’t know how you do it!
They are the perfect baking candy. Sweet, soft, colorful, loved them in the blondies. I make 4 desserts/sweets++ a week, I have to utilize every candy I can to keep things fresh. May as well take advantage of the seasonal stuff while I can!
The cut marks. Taking my time, super sharp knife, lining with foil, turning out onto a cutting board, then cutting. Although I’m sure that’s what you do. Your cut marks are always spot-on!
Gosh I love blondies SO much! They are buttery, toffee-like, gooey and so simple to make. I haven’t tried these m&ms before but I am thinking I’d love them!
buttery, toffee-like, gooey and so simple to make <-- AMEN!
Love the sound of these and those colours. Reminds me autumn is here!
Autumn has been coming and going for us – some bursts of summer thrown in some days, which is a blessing! :)
I just noticed those M&M’s at Walgreen’s over the weekend and was curious about the actual taste. On Monday one of my co-workers said she mixed up a bowl of them with candy corn and peanuts…..and today you share great blondie recipe!! I’m glad to see white choc flavored M&M’s and am feeling the need to buy some. I am also thinking maybe a small pan of these and a small pan of fluffernutter bars for the weekend. I knew I’d start wavering around once I saw your posts this week!!!
Serendipity! what are the odds with those M&Ms! Meant to be!
And glad I have you wavering. Ahhh, I’ve done my job :)
These look amazing! I love your tips about adding extra candies to the top and not using baking powder/soda. Can’t wait to try these!
Glad you like the tips. Thanks for LMK! I am trying to remember to include stuff like that more often.
I love how candies always have so much history! (yes this is my kind of studying). I am not from USA, so I find the history and am curious about the taste. Gathering from online opinion; I see that you guys ahve love hate relationship with it. Far enough but it is so cute!
Lovely blondies Averie, My white choc obenessed sister would love this
I know it’s totally an American thing and whenever I post stuff like this, I know I’ll have intl readers who won’t be able to find the exact ingredients, which is why white choc chips will work (or just regular M&Ms or similar) but yes, candy has such history and everyone has stories to tell about certain kinds of candy, childhood memories, etc.
