Cannabis Infused Rice Krispie Treats

Cannabis rice krispie treats are the easiest no-bake edible in the home kitchen. The recipe needs three ingredients (cannabutter, marshmallows, crispy rice cereal), runs about 20 minutes start to finish, and produces a 16-square pan that holds its dose distribution better than most bake-time edibles. The structural pick: use a known-potency cannabutter from a measured infusion batch, and divide the pan into 16 even squares so each treat carries a predictable dose. The recipe below produces 16 treats at approximately 10 mg of THC each, sized for the cautious home edible.

Why Rice Krispie Treats Are the Easiest Home Edible

No oven, no baking math, no decarb-while-cooking risk. The recipe heats the cannabutter only enough to melt the marshmallows (around 200 degrees Fahrenheit), which sits well below the 245-degree threshold where THC begins meaningful degradation. The marshmallow base also distributes the cannabutter evenly through the cereal volume, which means the dose lands more predictably across the 16 squares than it does in a sheet of brownies where the corner pieces sometimes pull more butter. For the first-time home edible cook this is the structural beginner pick. If you are tempted to speed-decarb in the microwave, do not: our debunk of the microwave decarb myth lays out why uneven heating produces weaker, less consistent results than a steady oven hold.

Ingredients

• 6 tablespoons cannabutter (or substitute 6 tablespoons cannabis-infused coconut oil)
• 10 ounces (1 standard 10-oz bag) miniature marshmallows
• 6 cups crispy rice cereal
• 1/4 teaspoon vanilla extract (optional, adds depth)
• Pinch of fine sea salt (optional, balances the marshmallow sweetness)

Equipment

• 9×13 inch baking pan (the standard size for a 16-square cut)
• Parchment paper or non-stick spray
• Large heavy-bottomed saucepan or Dutch oven
• Silicone or wooden spatula
• Measuring cups and spoons

Instructions

1. Line the 9×13 pan with parchment paper leaving a 1-inch overhang on the long sides, or grease with non-stick spray. Set aside.
2. In the large saucepan, melt the cannabutter over low heat. Hold the heat low. Do not let the butter brown or simmer.
3. Add the marshmallows once the butter is fully melted. Stir constantly with the spatula until the marshmallows fully melt and the mixture is smooth and glossy, about 4 to 6 minutes. Keep the heat low throughout.
4. Remove the saucepan from the heat. Stir in the vanilla extract and salt if using.
5. Add the crispy rice cereal in two batches, folding gently with the spatula until the cereal is evenly coated. Work quickly; the mixture stiffens as it cools.
6. Transfer the mixture to the prepared pan. Press into an even layer using lightly buttered hands, a sheet of parchment, or the back of a buttered measuring cup. Avoid pressing too hard; over-compacted treats turn dense and chewy. Aim for an even but loose pack.
7. Let the treats cool at room temperature for 30 minutes, then cut into 16 even squares using a sharp knife (4 cuts long-ways, 4 cuts short-ways). Cut on a cutting board after lifting the entire slab out using the parchment overhang.

Dosing Math

The dose in the finished treat depends on the potency of your cannabutter. The standard reference: 1 cup of cannabutter made from 1 ounce (28 g) of 20-percent THC flower carries roughly 3,640 mg of active THC at a 65 percent infusion efficiency (the conservative working number from our cooking with cannabis oil pillar). That cup contains 16 tablespoons. So each tablespoon of that cannabutter carries roughly 227 mg of THC. The recipe uses 6 tablespoons of cannabutter, which puts about 1,365 mg of THC across the full pan. Divided across 16 treats, that is roughly 85 mg per treat. That is a heavy dose. For a 10 mg per treat target dose, use 1 tablespoon of full-potency cannabutter and 5 tablespoons of regular non-infused butter, which drops the per-treat dose to roughly 14 mg. For a 5 mg dose, halve again.

The cleanest way to land a predictable per-treat dose: start with a measured low-potency cannabutter batch. If your cannabutter was made from 7 grams of 20-percent THC flower in 1 cup of butter, that whole cup carries about 910 mg of THC, and 6 tablespoons carries 341 mg. Divided across 16 treats, that lands at roughly 21 mg per treat. Cut the treats in half to bring it down to a manageable 10 to 11 mg edible. This is the structural pattern: measure the input, do the math, decide your serving size, do not eyeball the dose.

Storage and Shelf Life

Store the treats in an airtight container at room temperature for up to 3 days. The marshmallow base goes stale quickly, faster than the brownies or cookies do, which is part of why this is the small-batch make-and-eat recipe rather than the freezer-stockpile recipe. For longer storage, refrigerate up to a week or freeze individually wrapped treats up to 2 months. The cannabutter potency stays stable through refrigeration and freezing.

Variations

Brown butter the cannabutter for a nuttier flavor profile. Heat the cannabutter over low heat until the milk solids brown (about 6 to 8 minutes), watching constantly so the butter does not burn. The brown-butter version pairs well with a pinch of flaky sea salt sprinkled on top of the treats before they cool.

Add 1 cup of chopped chocolate or chocolate chips to the cereal mixture for a chocolate-studded variation. Stir the chocolate in with the cereal so the marshmallow heat melts it just enough to create chocolate streaks without fully integrating.

Swap the crispy rice cereal for cocoa puffs, fruity pebbles, or chocolate rice puffs for the flavored cereal version. The dose math stays the same; only the base cereal changes.

Why This Recipe Is the Beginner Pick

Three structural reasons. First, no decarb-during-cooking step. Your cannabutter handled the activation; the cereal step just distributes the activated butter into the finished treat. Second, the heat stays low enough to avoid degrading cannabinoids. The marshmallow melt point sits in the 175 to 200 Fahrenheit range, well under the 245 degree degradation threshold. Third, the dose distribution is more even than baked goods because the cannabutter mixes thoroughly with the marshmallow base before the cereal goes in. Corner pieces and middle pieces hit the same.

For the next step beyond this recipe, our hash brownies recipe walks through the same dosing math applied to a baked-goods format. Our cannabis gummies recipe covers the infused-syrup format. For the foundational decarb and infusion process the pillar at cooking with cannabis oil is the parent.

Frequently Asked Questions

How long do cannabis rice krispie treats take to kick in?

Most edible-format cannabis hits between 30 and 90 minutes after eating, with peak effects around 2 to 3 hours after the dose. An empty stomach speeds onset; a fatty meal can delay it. Wait at least 90 minutes before deciding whether to eat more.

How do you calculate the dose in a cannabis rice krispie treat?

Multiply your cannabutter’s THC content per tablespoon by the tablespoons in the recipe, then divide by the number of treats. Example: 6 tablespoons of cannabutter at 227 mg per tablespoon equals roughly 1,365 mg of THC across the recipe, which divides to about 85 mg per treat across 16 squares. For a lower target dose, use less cannabutter and substitute regular butter for the rest of the recipe volume.

Can you taste the cannabis in rice krispie treats?

Faintly. The marshmallow sweetness and the cereal flavor cover most of the cannabutter base note, especially in a brown-butter version. Hash-based cannabutter produces a cleaner final flavor than flower-based cannabutter.

How long do cannabis rice krispie treats last?

Up to 3 days in an airtight container at room temperature, up to a week refrigerated, or up to 2 months individually wrapped in the freezer. The marshmallow base goes stale faster than baked edibles, so this recipe is more suited to make-and-eat than long storage.
