Ingredients for 3 ingredient peanut butter rice krispie treats
Three magical ingredients create chewy, no-bake magic in minutes—no oven needed!
| Ingredient | Amount | Notes |
|---|---|---|
| Creamy Peanut Butter 🥜 | 1 ½ cups | Natural, no added sugar |
| Rice Krispies Cereal 🍚 | 6 cups | Original flavor preferred |
| Unsalted Butter 🧈 | ½ cup | Melted, full-fat preferred |
| Dark Chocolate Chips 🍫 | ½ cup | Optional but recommended |
The peanut butter is the star here—natural, no-sugar-added makes all the difference. Jif or Skippy are crowd-pleasers, but any creamy brand works. For extra richness, I sometimes mix in a tablespoon of melted coconut oil. The Rice Krispies? Original flavor only—the marshmallow bits in other varieties can make the treats too sweet. Grab the big family-sized bag at Walmart or Target—it's cheaper and lasts forever. Butter matters too—full-fat gives the best texture, so skip the light version.
No peanut butter? Almond butter or sunflower seed butter works in a pinch (though texture changes slightly). Skip the chocolate chips if you're allergic, but trust me, they're worth adding—they melt just enough to create pockets of gooey goodness. For a nutty twist, swap in chopped peanuts or walnuts instead. The treats stay chewy when cool but get soft and gooey when warm—serve warm for maximum indulgence. If you're feeling fancy, press them into a greased loaf pan for easy slicing.
These treats keep for 5-7 days in an airtight container at room temperature—though they rarely last that long. For extra shelf life, store them in the fridge for up to 2 weeks. Freeze any extras for 3 months by wrapping individually in plastic wrap. Pro tip: Wrap the whole pan in foil before slicing for perfect portions. The butter keeps them moist, so they won't dry out like store-bought versions.

Step-by-step instructions for 3-Ingredient peanut butter rice krispie treats
Here's how to make these chewy, no-bake treats in record time!
🍳 Step 1: Melt Butter and Peanut Butter Together
In a large microwave-safe bowl, combine the 0.5 cup unsalted butter and 1.5 cups creamy peanut butter. Microwave in 30-second intervals, stirring between each, until completely melted and smooth. You're looking for a silky, pourable consistency—no lumps allowed! This mixture should be warm but not hot to the touch.
I like to stir vigorously after each interval because peanut butter can sometimes separate when heated. If it's too thick, add 5-10 seconds more to help it flow. The butter and peanut butter together create that signature chewy texture we all love in these treats.
👨🍳 Step 2: Stir in Chocolate Chips (If Using)
Remove the peanut butter mixture from the microwave and let it cool for 1 minute—just enough to handle comfortably. Then fold in the 0.5 cup dark chocolate chips using a silicone spatula. Work quickly but thoroughly so the chocolate melts slightly from the residual heat.
Here's the thing—if you skip this step, you'll still have delicious treats, but the chocolate adds that perfect crunchy contrast. I always use dark chocolate chips because they melt more smoothly and add depth of flavor. If your hands get sticky, wet them slightly under cold water to help with mixing.
🥘 Step 3: Mix in Rice Krispies Cereal
Add the 6 cups rice krispies cereal to the peanut butter mixture and stir gently but thoroughly. You'll want to distribute the cereal evenly without crushing it—those little pieces are what give these treats their signature crunch. The mixture should look like a thick, clumpy batter.
I always recommend using the original flavor rice krispies because they have that perfect light, crispy texture. If you're using a different variety, they might get soggy faster. Work quickly here because the peanut butter mixture will start to set as it cools. Don't worry if it looks dry—it'll come together!
🔪 Step 4: Press into Pan for Perfect Shape
Lightly grease an 8x8-inch baking pan with butter or line it with parchment paper. Press the rice krispie mixture firmly and evenly into the pan using a greased spatula or your hands. I press down gently but firmly—you want it compact but not packed so tightly that it becomes dense.
This is where the magic happens! The pressure helps create those signature ridges and ensures even cooking (or in this case, setting) throughout. For extra-even distribution, I sometimes tap the pan gently on the counter a few times after pressing. Let it sit for 5 minutes while you prepare your cutting tools.
⏰ Step 5: Chill and Cut into Squares
Refrigerate the pan for 10-15 minutes until the treats firm up enough to cut. You'll know they're ready when you can see clean edges when you lift a corner. This chilling step is crucial—it prevents the treats from crumbling when you cut them.
Using a sharp knife, cut the treats into 16 even squares (4 rows by 4 columns). For clean cuts, dip your knife in hot water between cuts and wipe it dry. Store any leftovers in an airtight container at room temperature for up to 5 days—though I doubt they'll last that long!
Pro Tips For Making 3 Ingredient Peanut Butter Rice Krispie Treats
- MELT BUTTER FIRST: I learned this the hard way—mixing cold butter into peanut butter makes a greasy, sticky mess. Melt the butter first (about 2 minutes in the microwave, stirring once), then stir it into the peanut butter until fully combined. The mixture should be smooth and pourable, not lumpy.
- USE A HEAVY POT: This isn’t the prettiest method, but it’s the tastiest. Cook the peanut butter-butter mix in a heavy-bottomed saucepan (even a small one) over medium heat. Light-colored pots scorch; stainless steel or cast iron keeps things even. Stir constantly—after burning three batches, I finally figured out the pot matters more than I thought.
- DON’T SKIP THE CHILL: The chocolate chips will sink to the bottom if you pour the hot mixture into the cereal. Let the peanut butter mix cool for 5 minutes after removing from heat, then fold in the chips. This ensures even distribution and prevents a chocolate-heavy bottom layer—your future self will thank you.
- PRESS FASTER, CUT LATER: Once the cereal is mixed in, work quickly to press it into the pan. Use a greased spatula to smooth the top, then let it set for 10 minutes before cutting. If you wait too long, the treats will stick to the pan and break apart. A sharp knife dipped in hot water makes clean cuts—no need for fancy tools.
Essential equipment for this dish
Microwave Essentials
Your microwave is the star of this recipe—no oven required! I use a 1,200-watt microwave (like the GE JES1230S) for even heating, but any standard model works. The 30-second intervals are critical: overcooking can burn the peanut butter or melt chocolate chips too quickly. 🔥
Mixing Tools
A silicone spatula (I love the OXO Good Grips) is perfect for stirring the warm peanut butter mixture without melting your hands. For mixing in Rice Krispies, a wooden spoon works too—just avoid metal if the mixture is hot. A large microwave-safe bowl (like Pyrex) prevents spills during stirring.
Pan Prep
An 8x8-inch baking pan is ideal, but any similar size works. I grease mine with butter (using a pastry brush) or line it with parchment paper for easy removal. For extra-even pressing, I use a small offset spatula (like Cuisinart) to smooth the top after pressing.
Cutting Tools
A sharp chef's knife (I prefer Mercer Culinary) gives clean cuts. Dip it in hot water between slices to prevent sticking—this is my secret for perfect squares every time. For portion control, I also keep plastic wrap handy to wrap individual treats before storing.
Storage Containers
An airtight container (like Rubbermaid Brilliance) keeps treats fresh for days. I store them in square containers to maintain their shape, and a small ramekin works for single servings. For freezing, I use quart-sized freezer bags with zip-top closures to prevent freezer burn.

Frequently asked questions
Why do I need to chill the treats before cutting?
The 10-15 minute chill is key to prevent crumbling when you cut. Without it, the peanut butter mixture stays too soft and the Rice Krispies lose their structure. This step also helps the treats hold their shape when sliced into perfect squares. If you're impatient, chill for at least 5 minutes—just know the edges may be slightly messier.
Can I make these treats without chocolate chips?
The chocolate chips are optional but add a nice contrast in texture. If you omit them, you'll still get chewy, peanut-buttery treats. For a different twist, try adding 1/2 cup chopped peanuts or walnuts instead—they'll stay crunchy and add protein. Just stir them in right before pressing into the pan.
What if my peanut butter mixture gets too thick?
If your mixture feels too stiff after melting, microwave it in 5-second bursts until smooth again. Never add liquid—it'll make the treats soggy. The peanut butter should be warm but pourable. Pro tip: Use a silicone spatula to scrape the sides of the bowl while microwaving to ensure even melting.
How do I store leftovers for maximum freshness?
Keep treats in an airtight container at room temperature for up to 5 days. For longer storage, refrigerate for 2 weeks or freeze for 3 months. Wrap individual squares in plastic wrap before storing to prevent sticking. The butter keeps them moist, so they won't dry out like store-bought versions.
Can I make these treats with almond butter instead?
Yes, but expect a slightly different texture. Almond butter is less sticky than peanut butter, so you may need to add 1 extra tablespoon of melted butter to bind everything together. For best results, use a 1:1 substitution and press the mixture extra firmly into the pan. The flavor will be nutty and delicious, just not identical to peanut butter.
