Essential Ingredients for Your Crumbl Rice Krispie Bar Cookies
Crafting these delectable no-bake cookies requires a handful of simple ingredients, each playing a crucial role in achieving the perfect taste and texture. For precise measurements, please refer to the detailed recipe card below.
- Rice Krispie cereal – The cornerstone of our recipe! While the Kellogg’s brand is classic, any brand of crisp rice cereal will work beautifully. The most important tip here is to ensure your cereal is fresh. Stale cereal can lead to a less crunchy, somewhat dull final product, so check the expiry date for maximum snap and crackle!
- Mini marshmallows– These are key for the gooey, sticky binding that holds our cookies together. You’ll need one standard 10oz bag. Just like the cereal, freshness is paramount. Old or hardened marshmallows will result in stiff, rock-hard Rice Krispie treats, which is exactly what we want to avoid for that perfect chew.
- Butter– Butter adds richness and helps create that smooth, melt-in-your-mouth texture. For this recipe, salted butter is highly recommended. The touch of salt effectively balances the intense sweetness of the marshmallows, creating a more complex and appealing flavor profile that prevents the cookies from being overly sugary.
- Vanilla extract– A splash of pure vanilla extract is a game-changer! It deepens the flavor of the marshmallows and butter, adding a warm, aromatic note that enhances the overall deliciousness of these sweet treats. Don’t skip this for an extra layer of flavor.
- Mini dehydrated marshmallows– This is the secret ingredient for the “Crumbl twist”! These are the tiny, airy marshmallows typically found in hot chocolate packets. They add an extra textural dimension and a concentrated burst of vanilla sweetness, making these cookies truly special and reminiscent of Crumbl’s signature style. You can find them in the baking aisle or sometimes near hot chocolate mixes.
Step-by-Step Guide to Making Crumbl Rice Krispie Bar Cookies
Creating these no-bake marvels is incredibly simple and comes together in just a few easy steps. Below is a concise overview, but for comprehensive, detailed instructions, be sure to consult the full recipe card.
- Prepare Your Workspace: First, line a large baking sheet with parchment paper. This crucial step prevents sticking and makes transferring your finished cookies a breeze. Set it aside for later.
- Melt Together the Base: In a generously-sized, microwave-safe bowl, combine your mini marshmallows and butter. Microwave them on high for 1 to 2 minutes, pausing halfway to stir, until they are completely melted and smooth. Stir vigorously until the mixture is fully combined and uniform, then incorporate the vanilla extract, mixing until fragrant.
- Combine with Cereal: Add the Rice Krispie cereal to the marshmallow mixture. Using a sturdy spatula, fold the cereal into the gooey base until every piece is thoroughly coated. Once combined, gently fold in the mini dehydrated marshmallows. Be careful not to crush the cereal or the delicate dehydrated marshmallows too much.
- Shape Your Cookies: Lightly grease your hands or a large cookie scoop (a 1/3 cup scoop works perfectly for generous, Crumbl-sized cookies). Scoop out rounded portions of the mixture and place them onto the prepared parchment-lined baking sheet. Using your greased hands, gently shape each mound into a flat, round cookie form, similar to a hockey puck. Avoid pressing too firmly, as this can make your treats dense.
- Allow to Set: Once all your cookies are shaped, let them rest and set at room temperature for at least 30 minutes. This allows them to firm up slightly and become perfectly chewy before you enjoy them!






Pro Tips for Perfectly Chewy Rice Krispie Bar Cookies
To ensure your Crumbl Rice Krispie Bar Cookies turn out absolutely perfect every time, keep these expert tips in mind:
- Don’t Overcook Marshmallows: When melting the marshmallows and butter, heat them just until they are fully melted and smooth. Overheating can make the marshmallows tough and lead to hard Rice Krispie treats. Low and slow in the microwave or a double boiler is best.
- Use Fresh Ingredients: As mentioned, fresh Rice Krispies cereal and fresh marshmallows are non-negotiable for the best texture. Stale ingredients will compromise the crunch and chewiness.
- Avoid Over-Mixing: Once the cereal is added, mix just enough to coat everything evenly. Over-mixing can crush the cereal and reduce its desired crispness.
- Gentle Shaping is Key: When forming your cookies, use lightly greased or damp hands and press gently. Pressing too hard will compact the mixture, resulting in dense, brick-like treats rather than light and airy ones.
- Parchment Paper is Your Friend: Always use parchment paper on your baking sheet. It makes cleanup incredibly easy and prevents any sticky situations when removing the cookies.
Frequently Asked Questions (FAQ)
How to store these Rice Krispie bar cookies?
For optimal freshness and chewiness, store these cookies in an airtight container at room temperature for up to 2 days. The fresher they are, the better the texture, so try to enjoy them within that timeframe.
Do Rice Krispie treats need to be refrigerated?
No, these cookies absolutely do not need to be refrigerated. In fact, keeping them in the fridge will cause them to become super hard and lose their delightful chewy texture. Always store them at room temperature.

Can I freeze these Rice Krispie bar cookies?
While technically possible, freezing is not recommended for these Rice Krispie bar cookies. They will lose their optimal texture and become somewhat brittle or chewy in an undesirable way upon thawing. Fresh is always best for these treats.
Can I make this recipe with another cereal?
Absolutely! This recipe is incredibly versatile and works well with a variety of crispy cereals. Here are some fun alternatives you can try to customize your treats. Remember to add the cereal slowly, as different cereals might absorb the marshmallow mixture differently, potentially requiring slightly more or less liquid:
- Chocolate Krispies: For a delicious chocolatey twist.
- Fruity Pebbles: Adds a vibrant color and fruity flavor.
- Cinnamon Toast Crunch: Offers a warm, spiced flavor and extra crunch.
- Cheerios: A classic alternative that provides a slightly different texture and wholesome flavor.

Can I make smaller catering-sized Rice Krispie bar cookies?
You certainly can! For smaller, bite-sized portions perfect for catering or a dessert buffet, simply use a smaller cookie scoop. Instead of a 1/3 cup scoop, opt for a 1- or 2-tablespoon scoop. Since these are no-bake, they are incredibly forgiving, allowing you to easily adjust the size to your preference without impacting the final outcome.
Can these Rice Krispie treats be made into bars instead of cookies?
Yes, absolutely! If you prefer the traditional bar format, you can easily press the mixture into an 8×8 or 9×9 inch baking pan lined with parchment paper. Once set, simply slice them into squares or rectangles before serving.
A crucial tip for making bars: do not press the Rice Krispie treat mixture down too hard into the pan. You want to gently spread it and allow it to settle and set. This gentle handling ensures light, airy, and perfectly chewy Rice Krispie treat bars, avoiding a dense and hard texture.
