What if you took one of the few breakfast cereals that doesn’t have a metric ton of sugar per box and loaded it up with butter and marshmallows? Like candy apples or smores, the humble Rice Krispies treat is an iconic snack food and a microcosm of what makes so much about munching out in America great. Simply take an innocent cereal, cracker, or fruit, and fry it, or encase it in caramel, marshmallows, or whatever your heart desires.

According to an article in Kellogg’s hometown Battle Creek Enquirer, a Kellogg’s company archivist stated that the Krispies Marshmallow Squares recipe that we all know and love first appeared on cereal boxes in 1940. The simple, three ingredient article fit squarely into a time of austerity, world war, and simpler culinary tastes among American consumers. 

Fast forward 80-something years, and this gooey, sweet, crunchy treat is still very much in the “whoa I ate a whole pan of these,” category of snacks. 

But could they be improved by adding THC? Of course they could, as well as by including a fourth Rice Krispies elf (Dave) who is spending the summer as a whitewater guide in Colorado and learning how to play electric mandolin. 

So without further ado, let’s see how you can snap, crackle, pop, laugh, stare at the ceiling, and collapse on the couch.

Why edibles are great 

You and your fellow elves may usually prefer to pass a joint or blunt, or spark up the ol’ vaporizer and release some clouds. Edibles may not be your go-to for getting high, but they really shouldn’t be overlooked. 

While smoking is simple and straightforward and the effects are felt almost instantly, edibles have to work their way through the digestive system. This means they take a lot longer to kick in, but the high can be much more immersive and a truly fun and unique experience.

Edibles are also great for people who can’t smoke or just don’t like the taste or smell of smoke and would prefer not to send a skunky cloud of weed smoke wafting in all directions. 

Eating weed may not ever become your daily method, but there’s a lot to love about it, and more than enough reason to give it a shot.  

What not to do with edibles

It’s an edibles cautionary tale as old as time: You sit down and pop an edible, wait 45 minutes or so and….nothing. At the crossroads, you can either wait longer, or take another dose, convinced you simply didn’t take enough the first time. 

You can see where this is going. No sooner have you taken the second dose, the first dose starts to kick in and you’re in for a long night of staring at the Rice Krispies box waiting for one of the elves to make a move. 

With edibles, things can take a while to kick in. Make sure to start with a small dose the first time you’re trying out a new edible, and give it at least an hour or so before taking more. After all, if you’re taking edibles then chances are you’re not in a huge rush anyway. 

The other big mistake is to skip this next step.

What is decarboxylation? 

When making edibles, you first have to complete a process known as decarboxylation, which is far easier than it sounds. Basically, it involves applying heat to cannabis to convert the THCA to THC. Without this step, you’ll have a delicious edible that won’t get you where you want to go. 

All you need to do is grind up some cannabis and bake it in the oven for about 30-45 minutes at around 220-245°F (105-120°C). You may also want to crack a window and keep an eye on things to make sure the herb doesn’t scorch.

How to make cannabis butter

Now that you have some decarboxylated weed, you can make what is the most crucial ingredient in countless edible recipes — an infused fat. With an infused fat like cannabis butter or oil, you can make any food into an edible simply by adding a dollop of butter or oil. It’s really that simple. 

Here’s what you’ll need:


You can make cannabis butter in a crock pot or slow cooker, but the most straightforward way is in a saucepan. 

Put a cup of water and a cup of butter in a saucepan and simmer until the butter melts. Mix in the decarboxylated cannabis and simmer at around 160-180°F (70-80°C) for 2-3 hours. Keep a careful eye to make sure the mixture doesn’t boil, and after 2-3 hours take it off the heat. After the mixture has cooled, just pour it through the cheesecloth into a container of your choosing, and voila - you have cannabis butter!

How to make weed Rice Krispies treats

To make Rice Krispies treats with weed, your best bet is to start at the source — in Battle Creek, Michigan, the home of Kellogg’s. Actually, just go to the internet, where Kellogg’s has uploaded the extremely simple three-ingredient recipe.

  • In a large saucepan, melt the butter on low heat. Stir in the marshmallows and keep on heat, stirring until the mixture is melted.
  • Remove from heat and add in the Rice Krispies cereal, stirring well until it’s coated.
  • Press the mixture into a 13 x 9 x 2 inch pan coated with cooking spray. Cut into 2 inch squares and try not to eat all of them right away.

A note about cannabis dosing and edibles

How potent a cannabis edible is depends on a variety of factors including the amount and THC concentration of the weed you used to make it, your tolerance, and how large a dose you took. 

For this recipe, it all depends on the strength of the cannabis butter used. We recommend using an online cannabis edibles dosing calculator to decide how much to put in.

Ultimately, only you know your tolerance. If it’s your first time with a specific cannabis infusion, consider starting with a low dose and waiting patiently to see how you feel. You could also use half regular butter and half infused butter in the recipe, it’s all up to you.

  1. I have a question about making a weed edible. The recipe calls for cannabis butter,
    but can I add like shake weed or bud weed also to recipe?

  2. I just made some butter with some really trashy leaves I saved from last summer. I added some good bud just to help. I made rice crispy treats. They have a green tinge to them. Should be strong but who knows. Worst case I wasted some butter, marsh mellows and cereal.
