This air fryer rice crispy treats recipe transforms a childhood classic into a quick, crispy delight—no oven required. The secret lies in the air fryer’s precision heat, which creates golden, crunchy edges while keeping the centers soft and gooey. I’ve tested countless variations, and this method delivers foolproof results every time, cutting traditional baking time from 30 minutes to just 15 minutes. The process is simpler than you’d expect: melt butter (or vegan butter) with marshmallows, stir in cereal until fully coated, then press the mixture into the air fryer basket. The key to achieving that perfect crispy texture is pressing the treats firmly and air-frying at 350°F for 10–15 minutes, flipping halfway. This ensures even browning without burning, making it ideal for beginners or anyone short on time. What you’ll end up with is a batch of no-bake treats that are irresistibly crunchy on the outside and melty on the inside—just like the ones you loved as a kid, but with a modern twist. The air fryer’s even heat distribution means no soggy spots or uneven cooking, and the crispy edges add a satisfying texture that’s hard to resist. These treats are perfect for parties, potlucks, or a quick dessert when you’re craving something sweet but don’t want to turn on the oven. Plus, they’re customizable—swap out the cereal for gluten-free or vegan options, or add mix-ins like chocolate chips or nuts. Let’s get started!
Ingredients for air fryer rice crispy treats
Just nine ingredients for a nostalgic dessert with a modern twist—no oven needed.
| Ingredient | Amount | Notes |
|---|---|---|
| Unsalted Butter 🧈 | ½ cup | Vegan butter works too |
| Mini Marshmallows 🍫 | 10 oz | Regular marshmallows work |
| Rice Cereal 🍚 | 6 cups | Original or gluten-free |
| Vanilla Extract 🌿 | 1 tsp | Pure vanilla preferred |
| Sea Salt 🧂 | ¼ tsp | Fine grain preferred |
| Dark Chocolate Chips 🍫 | ½ cup | Optional for mix-ins |
| Peanut Butter 🥜 | ¼ cup | Optional for mix-ins |
| Almond Extract 🌿 | ½ tsp | Optional for flavor variation |
| Coconut Oil 🥥 | 1 tbsp | For greasing air fryer basket |
| Powdered Sugar 🍚 | 1 tbsp | For dusting treats |
The butter and marshmallows are the heart of these treats. Mini marshmallows melt faster and create a lighter texture, but regular ones work too. For the butter, vegan butter is a great swap if you're avoiding dairy—just make sure it's high-quality like Earth Balance or Miyoko's. The rice cereal should be the original kind (not the puffed rice cereal)—it's got that perfect crunch. I always grab the Kellogg's Rice Krispies from the store, but any brand works. If you're making these for a party, double the batch—people disappear when these come out.
No vanilla extract? Almond extract at half the amount adds a nice twist, or skip it entirely if you prefer the classic flavor. Want extra crunch? Toss in chopped nuts or pretzels while the mixture is still warm. The chocolate chips and peanut butter are optional but add a fun texture contrast. If you're using them, dark chocolate chips melt better than milk chocolate in the air fryer. For extra flavor, add a pinch of cinnamon or a splash of orange extract to the butter-marshmallow mixture before stirring in the cereal. And if you're feeling fancy, swap the powdered sugar for crushed freeze-dried strawberries for a fruity kick.
These treats are best made fresh, but they keep for about 3-4 days in an airtight container at room temperature. If you're making them ahead, store the unmixed butter-marshmallow mixture in the fridge for up to 2 weeks—just reheat gently before adding the cereal. The air fryer basket should be lightly greased with coconut oil before pressing the treats in, but don't overdo it or they'll be greasy. For a crispier texture, press the mixture firmly into the basket and flip halfway through cooking. And if you're feeling ambitious, make them in mini muffin tins for bite-sized treats—just bake at 350°F for 8-10 minutes.

Step-by-step instructions for no-bake air fryer rice crispy treats
Here's how to make crispy, gooey treats without a single oven turn-on.
Melt Butter and Marshmallows Together
In a large microwave-safe bowl, combine the 0.5 cup unsalted butter and 10 oz mini marshmallows. Microwave in 30-second intervals, stirring well between each, until the marshmallows are completely melted and the mixture is smooth. You'll know it's ready when it looks glossy and pulls away from the sides of the bowl.
This step is crucial for creating that signature crispy-yet-gooey texture. If you see any unmelted marshmallow bits, stir them in and microwave for another 10 seconds. The mixture should be hot but not boiling—just warm enough to coat the cereal perfectly.
Mix in Cereal and Flavorings
Immediately after melting, add the 6 cups rice cereal, 1 tsp vanilla extract, 0.25 tsp sea salt, 0.5 cup dark chocolate chips, 0.25 cup peanut butter, and 0.5 tsp almond extract. Stir vigorously with a wooden spoon or silicone spatula until every piece of cereal is fully coated and the mixture looks dry.
Work quickly here—the mixture will start to set as it cools. If it looks too thick, microwave for 10 seconds to loosen it up. You want the cereal to be completely dry to the touch, with no sticky spots. This ensures maximum crunch when we air fry.
Press into Air Fryer Basket
Lightly grease your air fryer basket with 1 tbsp coconut oil using a paper towel. Press the cereal mixture firmly and evenly into the basket, creating a layer about ½-inch thick. Use the back of a spoon to smooth the top and create clean edges.
Here's the thing—don't worry if it looks messy. The air fryer will crisp everything up beautifully. For extra crispiness, you can even press it into a greased loaf pan first, then transfer to the air fryer basket once set. This makes slicing easier later.
Air Fry for Perfect Crispiness
Preheat your air fryer to 350°F for 3 minutes. Then place the basket in the air fryer and cook for 8-10 minutes, checking at the 7-minute mark. You're looking for a golden brown color on top and edges that pull away slightly when you lift a corner.
Watch carefully—every air fryer is different. If it browns too quickly, reduce the temperature to 325°F for the remaining time. The treats are done when they're crispy on the outside but still soft and gooey inside. Let them cool in the basket for 5 minutes before removing.
Dust and Slice for Serving
While still slightly warm, dust the top generously with 1 tbsp powdered sugar using a fine-mesh sieve. This adds that classic sweet finish. Let cool completely for 10 minutes before slicing into squares or rectangles with a sharp knife.
For the best texture, serve at room temperature. If you need to store them, keep in an airtight container for up to 5 days—though they're so good, they probably won't last that long! The air fryer method gives you that perfect crispy exterior while keeping the centers perfectly gooey, just like the classic version but with a fun twist.
Pro Tips For Making Air Fryer Rice Crispy Treats
- Preheat Like a Boss: Turn that air fryer on high for 3 full minutes before adding your marshmallow-butter mix. I learned this the hard way—skipping it makes the treats stick to the basket like sad, gummy glue instead of crisping properly. (Yes, even if you're impatient like me.) ---
- Toast Cereal First: Lightly toast your rice cereal in the air fryer (350°F for 2-3 minutes) before mixing it in. It adds a nutty crunch that the microwave version misses, and it soaks up less butter later. (Your future self will notice the difference.) ---
- Salt the Marshmallows: Sprinkle half the sea salt directly over the marshmallows before they melt—this gets it evenly distributed, not just floating on top like confetti. I was skeptical until I tried it; now it’s non-negotiable. ---
- Divide and Conquer: Split your mixture into two batches if your air fryer is small. Overcrowding = soggy centers and uneven cooking. (This isn’t the prettiest method, but it’s the tastiest.) Use a greased silicone mat for easy release.
Essential equipment for perfect results
Air Fryer Essentials
The only must-have tool for these treats is a quality air fryer—I recommend the Ninja Foodi DualZone for even cooking or the Cosori Premium for precise temperature control. Both handle the 350°F setting perfectly without hot spots. A microwave-safe bowl (like Pyrex) is critical for melting the butter-marshmallow mixture safely. 🌡️
Greasing Like a Pro
Use coconut oil (not butter) to grease your air fryer basket—it resists burning at high heat and adds no flavor. Lightly coat the basket with a paper towel dipped in oil, then wipe away excess. For extra crispiness, I press the mixture into a greased loaf pan first, then transfer to the basket after it sets slightly.
Mixing Tools Matter
A wooden spoon or silicone spatula works best for stirring the cereal mixture—metal can melt marshmallows unevenly. For pressing the treats, use the back of a spoon to create clean edges. A sharp knife (like a Victorinox 8-inch) is essential for slicing once cooled. 🔪
Temperature Control Tips
Most air fryers run 25-50°F hotter than ovens, so preheat to 350°F for exactly 3 minutes before adding treats. Use an infrared thermometer (like the Thermoworks One) to verify your air fryer's actual temperature—some models vary wildly. If your treats brown too fast, drop to 325°F.
Storage Containers
Store leftovers in an airtight container with parchment paper between layers to maintain crispiness. I use Rubbermaid Brilliance containers—they’re stackable and keep treats fresh for 5 days. For longer storage, freeze portions in ziplock bags for up to 3 months. 🧊

Frequently asked questions
Can I make these treats without an air fryer?
Yes! If you don't have an air fryer, you can still make crispy treats by pressing the mixture into a greased 9x9-inch baking dish and baking at 350°F for 12-15 minutes. The texture will be slightly softer, but still delicious. For extra crunch, sprinkle powdered sugar on top before baking.
Why are my air fryer treats not crispy? Crispiness depends on pressing the mixture firmly into the basket and cooking at the right temperature.
Can I use regular marshmallows instead of mini marshmallows?
Regular marshmallows work just fine—they’ll just take slightly longer to melt completely. Cut them into smaller pieces before microwaving to ensure even melting. The texture will be slightly chewier, but still delicious. For a lighter texture, you can blend the marshmallows into a fluffier consistency before mixing with the cereal.
How do I make these treats vegan?
Swap the butter for vegan butter (like Earth Balance or Miyoko's) and use vegan marshmallows (like Dandies or homemade agar-based marshmallows). The rest of the recipe stays the same! For extra richness, add 1 tbsp coconut oil to the butter-marshmallow mixture. The texture will be just as crispy and gooey.
Can I make these treats ahead of time?
Yes, but store them carefully to maintain crispiness. Press the treats into the air fryer basket, then refrigerate for up to 2 hours before cooking. For longer storage, keep the unmelted butter-marshmallow mixture in the fridge for 2 weeks—just reheat gently before adding the cereal. Once cooked, store in an airtight container for 3-4 days or freeze for up to 3 months. Re-crisp in the air fryer for 2-3 minutes at 350°F if needed.
