Rice krispie cake monsters

Everyone LOVES krispie cakes, and these are rather wonderful rice krispie cake monsters that are perfect for that special treat any time of year. They are good rice krispie cakes recipes for Halloween as well; because they are very cute little monsters. Whether you are looking to celebrate a birthday, or Halloween, or just after a fun recipe for the kids, give this one a go. This is a lovely simple idea when you are looking for a basic alternative to chocolate chip cookies. It’s dead easy, and the kids will love it. Let us know how you get on with it too:

Makes 12-24 rice krispie cakes, depending on how big you make them.

Takes about 15 minutes total time depending on how long it takes to mould the monsters, and how messy you want the kids to get 😂 . Not really more than about 5-10 minutes cook time for meling the butter, and the M&Ms though.

Ingredients for rice krispie cake mix:

  • 3 tablespoons butter, we prefer unsalted butter here
  • 10 oz package  regular or mini marshmallows
  • 6 cups rice krispies cereal; you can substitute this with gluten free rice krispies if you want here too
  • 10 oz package ghoul’s mix M&Ms. Do take note if you are gluten free that only some M&M products are Gluten free, so check the labels before you make these
  • Candy eyeballs
  • Additional 1 tablespoon butter


  • 1. Melt 3 tablespoons of butter over medium heat (or low to medium) in a large saucepan. Do be gentle with this step, and it is OK to turn the heat down slightly if you need to. You don’t want the butter bubbling like mad in the pan, and turning brown
  • 2. Add marshmallows, and stir until they are fully melted. This is a lot of fun for the kids as who doesn’t love watching the sticky mess of a marshmallow melton. Turning to a low heat would be sensible here so as not to burn the marshmallows of course. This can cause a sticky mess in your pan, but it IS worth it for the taste. We promise you. This is where we are ever grateful that we have a dishwasher….
  • 3. Remove from heat and add cereal and M&Ms. Stir until combined.
  • 4. Make sure you combine these really well, and otherwise your monster cakes won’t be even. If you won’t have the ghoul’s mix M&Ms, don’t worry, just use what you want. We think these are a great little treat anytime of year. Just grab a bag of M&Ms, whatever you can find, and just have a bit of fun.
  • 5. Butter your hands, then grab handfuls of the mixture and form a ball. You need to butter your hands to make it easier to work with the cakes. Kids LOVE this bit, but you do need to make sure that those hands don’t end up touching more than you had bargained for, as otherwise you might be wiping butter off door handles for weeks to come….
  • 6. Add the candy eyeballs, and press them in slightly so they will stay put. We admit that eyeballs can be hard to come by if it isn’t Halloween. We have found them on Amazon all year round though, so do take a look there. Alternatively, make it fun looking for them on the next shopping trip out perhaps?

Once you have added the eyeballs, set them out on a baking sheet or baking tray

You may need to re grease your hands a time or two throughout the process, so that the mixture won’t stick to your hands.

Voila – your rice krispie treats (or is it rice crispy treats depending on where you are from 😉 )are ready!

You could add a little golden syrup into the krispie treat for a little more stickiness, but entirely up to you and your kids’ tastes. It you wanted a little more flavour, vanilla extract can work well here too.

Turn them into mummies?

If you wanted a bit of a twist on these monster cake rice crispies. Why not put a bit of white frosting into a piping bag, and criss cross back and forth on the cakes after you have completed.

Guess what – from monsters to mummies?!? If you are after that Halloween treat, this could be another take on the cake. 😂
