A vegan rice krispies recipe? Yes, please! You can make this delightful treat vegan simply by choosing vegan marshmallows and plant-based butter (or coconut oil). These “Mice Krispies Treats” decorated with sweet chocolate mice faces are a fun treat to make for Halloween—especially if you’re dressed up as cat!

Are Rice Krispies Vegan?

Rice krispies seem innocent enough but there’s actually a couple non-vegan ingredients inside them, the main ones being marshmallows and butter.

What’s the problem with regular marshmallows, you ask? Generic marshmallows are made with gelatin which comes from animal skin and bones. Nasty stuff.

Luckily, vegan marshmallows are much easier to find these days. Dandies is the main brand available in the United States, but you can even find vegan marshmallows at Trader Joe’s now!

Without further ado, enjoy this vegan rice krispie treats recipe! And be sure to peek at the video to see exactly how these are made.

Why You Should Make a Vegan Rice Krispies Recipe

What’s more delightful than a chewy and crunchy sweet treat that relies on puffed rice crisps and gooey goodness? Well, not much! These vegan rice krispies are pinnacles of childhood nostalgia with no yucky gelatin to worry about!

Plus, they’re simply adorable with the addition of cute little chocolate ears and whiskers. Here are a few hefty highlights about why these mice krispies treats are so terrific:

  • Lunchbox Ready – These mice krispies make a great addition to your kid’s (or even your own) lunchbox! If you’re including some for your kiddo, it’s a great way for them to feel more included during Halloween when they may see other kids eating up non-vegan krispie treats.
  • Easy and Adorable – This recipe is rather simple and straightforward which is what makes it perfect for preparing in time for a haunted Halloween party!
  • Gloriously Gluten-Free – If someone in your family can’t have gluten and still wants a sweet and hearty treat, these mice krispies can’t be beat! Woo hoo!

Star Ingredients

Ingredients for the rice krispies mice krispies with puffed rice cereal, butter, marshmallows, and chocolate chips scattered around.

While there are but only a few ingredients needed for this vegan rice krispies recipe, they are mighty (just like mice)! All you need is your favorite puffed rice cereal, vegan butter, vegan marshmallows, and some chocolate chips to melt.

  • Puffed Rice – Rice is one of the most commonly consumed grains in the world. While it doesn’t take much to turn it into a sweet dessert, puffed rice adds a whole other dynamic of texture and taste. Naturally gluten-free, rice is generally safe for people with a range of food sensitivities to consume.
  • Vegan Marshmallows – What happens when you mix marshmallows with puffed rice? Magic. The gooey sweetness of marshmallow with crunchy rice is perhaps an underrated combination in a world dominated by cookiescake, and donuts.
  • Vegan Chocolate – Chocolate is one of the most beloved foods on earth—it’s a serotonin booster, a flavor booster, and just downright delicious (to many, at least). Here it is not the star of the show but rather a supporting role. To ensure that you’re buying fair trade chocolate, check this guide by the Food Empowerment Project!

How to Make

We’ve got you covered in this step-by-step tutorial but if you need some extra help, check out the video!

Melted vegan butter and marshmallows in a large pan.
  • Start by melting the vegan butter (either stick or spreadable butter is fine!) and marshmallows in a large saucepan over medium heat. Stir often to help it evenly melt and mix together.

  • Add the puffed rice cereal to the sauce pan and stir well to combine.

  • Remove mixture from heat and pour into a 9×9 pan and set aside to cool before cutting. Once it’s at room temperature you can slice it into mice-size rectangles.

  • Meanwhile, let’s make the mice features. On a piece of paper, sketch mice ears, place it on a cutting board, and cover with wax paper.
  • Heat chocolate chips (using microwave of double boiler) until melted. In a microwave, make sure to stir between 30-second intervals to prevent burning.

  • Pour melted chocolate into a plastic bag, cut a tiny hole in the tip, and pipe the chocolate onto the wax paper to form your mice ears, tracing over the parts you previously sketched. Set in the freezer for 20 minutes until the chocolate hardens.

  • While freezing, pipe the chocolate onto the rice krispies to form the mice eyes, nose, whiskers and tails. Then pipe chocolate onto the “head” to attach the frozen ears, working quickly to attach the ears so they don’t melt in your hands.
  • Allow to cool before enjoying or serving at a Halloween party!

Can You Store Rice Krispies?

Because puffed rice gets stale very quickly, it’s not advised to store these vegan mice krispies for too long but if you end up with more than you can chew, stick them in an airtight container for up to three days or store in the freezer for up to six weeks. Try to get as little air as possible in the container!

How to Have the Ultimate Vegan Halloween

Throwing a Halloween party? Here are some tips for making the most of your vegan Halloween!

Make some vegan mummy dogs, create some caramel apples, and bust out the vegan candy!
  • Save Your Pumpkin Carvings – Carving out a cute cow or spooked kitty? You can do so much with the scraps from pumpkin carvings! Soups, salads, pasta sauce, and more can be made from the seeds and flesh of the beautiful pumpkin.
  • Keep Decorations Sustainable – Whether it’s cutting up an old shirt, getting super crafty, or finding used decorations online or elsewhere, there are plenty of ways to avoid buying new decorations every year. Plus, your mini pumpkin may just last more than one season!

5 Fun Facts About Mice

  • Mice are very intelligent and use vocal noises, olfactory scents, and facial expressions to communicate with each other.
  • Mice are incredibly clean and organized. Within their intricate underground homes, they have specific areas for storing food, going to the toilet, and for shelter.
  • Whiskers help mice to sense smooth and rough edges, temperature change, and breezes.
  • Mice have incredible balance and can walk along thin wire.
  • Mice can jump down 12 feet without injuring themselves and can squeeze through a hole the size of a #2 pencil. If her head can squeeze through a hole, the rest of her body can fit as well.

  • In a large sauce pan over low heat, add vegan butter and marshmallows.
  • Stir regularly for about 7–8 minutes, or until largely melted.
  • Add cereal to the sauce pan and stir until well combined.
  • Press mixture into a 9×9 pan until it's about 1-inch thick but no thinner or they will be too thin to pipe the faces on. Set aside to cool before cutting into 12 mice-size rectangles.
  • Meanwhile, make the mice ears. Using a piece of paper, sketch mice ears, place it on a cutting board, and cover with wax paper.
  • Heat chocolate chips (using microwave of double boiler) until melted.
  • Pour melted chocolate into a plastic bag, cut a tiny hole in the tip, and pipe the chocolate onto the wax paper to form your mice ears. Set in the freezer for 20 minutes until chocolate hardens.

  • Allow to cool before enjoying or serving at a Halloween party!



  • If you’d prefer, you can melt the butter and marshmallows in a microwave instead of on the stove. To do so, in a glass bowl microwave for 30 second intervals, stirring between each, until marshmallows are fully melted. Then mix in cereal and stir until combined.
