Catching Up Over Christmas Rice Krispie Treats
Alright, let me just say up front, Christmas Rice Krispie Treats are my holiday cheat code. Every year, my sister insists on the “fancy cookies,” but let’s be real, these are the first things to disappear from the plate. I started making these in university because someone left a box of cereal behind in the dorm kitchen (cheers, Alicia!), and I haven’t stopped since. They’re festive, seriously easy, and have a way of making everyone feel about, oh, seven years old again. Once, I accidentally dyed my hands green making theseโlong story involving food coloring and a dodgy Ziploc bag. Anyway, don’t let that put you off. This is a classic with a Christmas jumper on.
Why Youโll Love These (According to My Family, Anyway)
I make this when Iโm just done fussing with cookie cutters or, honestly, when I forget to prep and need something in a hurry. My family goes absolutely bonkers for these because theyโre gooey, crunchy, andโunlike that yule log cakeโyou donโt need a PhD or endless patience. Heck, sometimes theyโre a little uneven; I just tell everyone itโs โrustic charm.โ (On a weird side note: the cat tried to eat one once, so apparently the appeal crosses species? Donโt give these to cats, though.)
Hereโs What Goes in (and Some Handy Substitutions)
- 6 cups Rice Krispies cereal (Or, Aldiโs crispy rice or honestly any off-brandโjust avoid the cocoa ones, unless youโre feeling wild)
- 1/4 cup unsalted butter (Salted butter works fine. My Nan always used Lurpak, but, er, donโt sweat it)
- 1 10oz bag mini marshmallows (Or the big ones chopped a bit; I only do this if I forget the little ones. Plus extra for, you know, โquality assurance tastingโ)
- Food coloring (Red and greenโgels make richer colors, but Iโve thinned them with a splash of water if desperate. Sometimes only had blue; made blue treesโno regrets!)
- Holiday sprinkles or mini M&Ms (Optionalโbut cโmon, Christmas means sprinkles. I grab fun ones from Sweetapolita every year)
- 1 tsp vanilla extract (Gives it a bit of extra oomph. Sometimes I skip it, but people seem to notice.)
Making the Magic Happen
- Grease a 9×13 inch pan with butter. Or spray it. (Or, one time, olive oilโฆ donโt recommend.)
- In a large saucepan, melt the butter on medium-low. Donโt wander off, butter burns fastโor it does if youโre me.
- Dump in the marshmallows and stir โtil everythingโs just about merged into one gooey blob. Procrastinators beware: remove it from the heat as soon as the lumps are mostly gone; otherwise, it gets too stiff.
- Off the heat, stir in the vanilla. Decided you want colored treats? Nowโs your moment! Divide mixture into bowls, add food coloring, andโcarefullyโstir. (This is where things look questionably edible. Donโt worry.)
- Pour over the Rice Krispies. I do this in two bowls if Iโm doing red and green. Mix quickly, but not franticallyโjust until coated.
- Press the mixture into your pan. I use a piece of parchment rubbed with butter so it doesnโt stick to my hands, but eh, wet fingers work too. (This is where I sneak a taste. Quality control is important.)
- Decorate with sprinkles and M&Ms, or whatever youโve got. Donโt sweat even coverageโmy kids usually cover one corner and leave the rest naked.
- Let set for about 30 minutes (I know, it feels like forever), then slice โem up and share. Or hide a square for yourself. No judgment here.
Musings & Notes (or, Lessons from My Kitchen)
- If the treats are hard as bricks, probably overcooked the mallows. Just means more dunking in tea, honestly.
- Iโve tried adding orange zestโtastes nicer than youโd think! Next time, though, less is more.
- Making ahead? I think these taste better the day after, but most of my family canโt muster that level of patience.
Variations Weโve Tried (Some Hits, Some Misses)
- Chocolate drizzle (itโs a winner, but makes more mess)
- Peanut butter swirlโfantastic, as long as no oneโs allergic. But when I tried butterscotch chipsโฆ eh, didnโt love itโprobably just me, though.
- Mini marshmallows on top for texture (kids love it, adults act like they do but secretly pick them off)
Tools and Workarounds
If you donโt have a big saucepan, you can melt the stuff in the microwave in 30-second bursts (use a huge microwave-safe bowl, trust me). Oh, and donโt stress if youโre missing a spatula; one time I used a clean pasta serverโworked a treat. For spreading, the back of a big spoon is just as good as anything fancy.

Storing These Beauties
Pop them in an airtight tin or container and theyโll last three days (so the internet claims, anyway), though honestly, in my house, it never lasts more than a day! They will dry out if you leave them uncovered, unless you live somewhere with rainforest-level humidity.
Serving โEm Up, Family Style
We always cut them into wonky squares or, if Iโm feeling extra, use a tree-shaped cookie cutter. Sometimes, I stack them on a cake stand like a wobbly little Christmas tree. My aunt (the rebel) crumbles one into her ice cream bowl. I say, you do you.
The Hard-Won (Sometimes Painfully Obvious) Wisdom
- I once tried rushing the melting step and ended up with semi-charred marshmallows. Thatโs a flavor no one needs. Take it slow!
- Pressing too hard makes them dense as bricks. Gentle patting, not Hulk smash. Actually, I find it works better if you just use the parchment and a light hand.
- I measured the cereal wrong once (added too much), so the bars fell apart. So now, I go for a heaping half of the box and top up only if it looks too gooey. Precision is not my forte.
FAQ โ Real Questions from Real (Slightly Panicked) Friends
- Why are my Krispie treats so hard? Oh, classic! You probably cooked the marshmallows too long, or packed โem in too tightly. Go easy next time; these are meant to be chewy, not dental work.
- Can I make them ahead? Absolutely. Just keep โem airtight. They start to taste a bit “meh” after 48 hours but, like, I highly doubt thatโll be a problem. Hereโs a handy tip sheet I like: Serious Eats Rice Krispies Guide.
- How fancy can I get? As much as you want! Food coloring, sprinkles, edible glitterโgo nuts (not literally unless you want nutty treats). Pro tip form a friend: Sallyโs Baking Addictionโs tree version looks impressive.
- Is there a vegan way? Yup! Use Dandies marshmallows and any non-dairy butter. Itโs a little stickier, but still yum.
- Do these freeze well? Sort of, but they defrost a bit soggy. I tried once for a partyโฆ wouldn’t recommend unless youโre desperate.
