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 (8×8 inch) Baking Pan
- 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.

In my opinion, if the blondies are “fudgy” then they are not really blondies :)
Just made these because we had some of candy corn m&m’s on hand. My husband brought them home by mistake instead of milk chocolate m&m’s. We weren’t fans of them and figured this would be the best way tokeep them from going to waste! I am sad to say I WAY under baked them because I didn’t fully read your last step. Whoops! I baked for 25 minutes but that wasn’t long enough in my oven. I didn’t toothpick test them which i should have. But I have another bag so I will try again. The edges were yummy though!
You could probably put them back in the oven for 5 mins if you just made them and they’re still in the pan, semi-intact. I mean, they won’t be super pretty :) but they’re salvageable. Yes, bake until done. Always. Ovens and personal preferences vary – you just have to try your gut, always, and bake until done, whatever that is in your world :) Glad you will try again!
Thank you!
I get spontaneous trait!

Man, those look SO GOOD! I tend to just pour those m&m’s right into my trap, but using them up this way is a waaaay better idea!! :)
Baking them in slows down the rate of just shoveling them into my trap as well :)
These look amazing!! Can’t wait to try them! I love all blondies!
Thanks, Jamielyn! These are the easiest blondies ever!
Sometimes I crave blondies but I’m too lazy to pull out every single measuring cup and heavy kitchen “equipment.” I’ll have to remember to try your basic blondie recipe!! Instant gratification. :D
Girl it’s the easiest recipe ever. Everything is “one” and the batter literally takes 5 mins to stir together. I relay and parlay this batter ALL the time!
Dude, how did I not know that M&M’s had a candy corn flavor out! Definitely need to stock up before they get rid of it! Pinned, of course! :)
Thanks for pinning (as always!) and while these were good, I am on the lookout for the pumpkin spice ones! Target was sold out of those when I went…
I bought a bag of the White Chocolate Candy Corn M&Ms. We (mostly me) ate the entire thing, and I still can’t decide if I like them. I’m not a candy corn fan, but they’re better than candy corn. It’s an interesting dilemma. I might have to buy another bag and make these before I make a final decision…
I love your rationale about buying another bag and make these before you make a final decision :) I agree, definitely no candy corn flavor for me or extremely subtle if it’s there.
Oh man! I want to make these, but I need to be good! :( I LOVE M&M’s candy corn. I didn’t buy them because I know I would eat the whole bag. If I had your blondies I would probably eat the whole batch! They look amazing!!!!!!!!!!!
Thanks Jennifer! Glad you love the M&Ms and they were perfect in bars like these!
I have never seen candy corn m&ms! How festive and fun. I also did not know how badly real candy corns would stick to the bottom of the pan unless buried in the batter. Great tip. Everything being a “one” in this is also fantastic because it makes it so easy to throw it all together and easily repeat it if you are in the kitchen without the recipe in front of you.
Little tips like the “one” and to bury the candy corns – glad you like those :) I’ve been trying to remember to add things like that lately!
Candy corn M&M’s?! I didn’t know Halloween could get any better! Thanks for sharing this creative way to use them!
And I would happily get a cavity over devouring these!
LOL!!
LOL!!
These blondies are studded with goodies! Love that they are so simple to put together! Pinning!
thanks as always for the pin, Anna!
I specifically did not buy the candy corn m&ms because the thought of candy corn m&ms grossed me out, happy to know they are more just like white chocolate. The m&ms are so cute and festive for this time of year am happy to know now that I will enjoy them! These blondies look gorgeous, I always enjoy reading your posts!
Totally along the white choc lines. Very little, if any,candy corn flavor!
I like chewy dense blondies too – my gluten-free version is even cakier than usual and based on your post, I’m going to try leaving out the baking powder next time. Thanks for the tip!
Oh girl with GF baking AND then also putting in baking powder, uh-oh – no way. LEAVE it out. You will be SO much happier with results. They’ll be fudgier and denser rather than dryer/crumblier. LMK how they come out next time after omitting the BP!
I Love how moist these are!! I am with you on the candy corn flavor!!
