How No Bake Cookies Became a Family Tradition
Some recipes just stick. For me, it’s this one. 3 ingredient no bake cookies were a staple in my grandma’s kitchen. I remember her scooping warm peanut butter into a saucepan while I measured oats with sticky fingers and scattered half of them on the counter. The smell of toasting oats and melty chocolate meant something sweet was coming fast—and without much cleanup.
Now I make them with Emma and Jack. My two wild kitchen buddies think the best part is licking the spoon (and they’re not wrong). The beauty of this recipe is that it feels like a little break in the day. There’s no stress, no need for timers or mixers—just a few scoops and a chill.
And if you’ve got ten minutes, a half-empty jar of peanut butter, and a forgotten bag of oats in the pantry? You’re already halfway there. We’ve made these on rainy weekends, holiday mornings, and on “oops, I forgot to make snacks” kind of days.
3-Ingredient No-Bake Cookies
Ingredients
- 1 ¾ cups old-fashioned rolled oats use gluten-free if needed
- ⅔ cup dark chocolate chips 70% cocoa recommended
- ½ cup natural runny peanut butter
Instructions
- Preheat the oven to 350 °F (180 °C).
- Line a large plate or board that fit your freezer width as you will pop this in the freezer later. Cover with parchment paper, lightly oil paper. Set aside.
- Line a large baking sheet with parchment paper and arrange the oats on the tray in a single layer.
- Roast the oats for 12 minutes, stirring halfway. Let them cool down on the tray at room temperature.
- Meanwhile, in a saucepan add peanut butter and your favorite chocolate chips. Make sure you pick the cocoa level that matches your tastebuds. I recommend 70% cocoa for a healthy treats, it’s lightly sweet but not too sweet, not too bitter. Go for 85% cocoa for ultra-low sugar, not sweet cookies and health conscious palate. If you prefer the cookies sweet, try 55% cocoa chocolate.
- Bring the saucepan over medium heat, warm, and stir with a rubber spatula until the ingredients are nicely melted. Remove from the heat.
- Stir the roasted oats immediately and vigorously. It’s okay if your oats it’s still warm. Stir quickly, to coat fully with the mixture. It’s important to be quick as the mixture dries out as you stir.
- Use a small cookie dough scoop to scoop out some cookie dough mixture, press firmly in the scoop to compact the cookie mixture then release it on the prepared plate. Lightly oil your finger tips and press the top of each cookie to flatten.
- Repeat until the whole mixture as been formed into cookies.
- Freeze the cookies for 15 minutes to quickly set them or simply place them in the fridge for 3 hours to firm up.

Why This Recipe Works (And How It Saves the Day)
You don’t need a mixer, a cookie sheet, or even much patience. The magic of 3 ingredient no bake cookies is how quickly they come together—and how well they hold up in the fridge all week. You toast the oats, melt chocolate and peanut butter, stir fast, scoop, and chill. That’s it.
What makes them reliable is the balance: the oats give a bit of chew, the chocolate binds once cooled, and the peanut butter adds creaminess and structure. Even if you forget an exact measurement, the recipe is forgiving.
They also work well for different diets and needs—vegan, gluten-free, or toddler-sized bites. Plus, you can double the batch and store them for quick snacks.
We’ve brought these to school potlucks, playdates, and even kept them in the freezer for late-night cravings. No one ever believes they’re made with just three ingredients.
Simple Ingredients, Big Flavor
The real charm of 3 ingredient no bake cookies is in their simplicity. You don’t need a long shopping list or complicated techniques—just three pantry staples that come together fast and taste like a treat you actually meant to make. Whether you’re baking with kids, prepping snacks for the week, or just need a late-night fix, these ingredients get the job done every time.
The 3 Core Ingredients in No Bake Cookie Magic
Rolled Oats
Oats are the base of most 3 ingredient no bake cookies for good reason. They add texture, heartiness, and that familiar chew we love. I always toast mine at 350°F for 12 minutes—it deepens the flavor and helps the cookies set better. Quick oats are fine, but avoid steel-cut, which stay too firm. Choose gluten-free oats if needed.
Peanut Butter
Smooth, runny peanut butter works best. It binds everything together and gives that creamy, nutty taste that makes these cookies so satisfying. If your peanut butter is thick or dry, the cookies may not hold. For a nut-free option, sunflower seed butter works great. Almond or cashew butter are also delicious swaps.
Dark Chocolate Chips
Use whatever dark chocolate fits your taste. I like 70% cocoa for a balanced sweetness, but 55% semi-sweet is great for kids, while 85% is perfect if you’re after a rich, low-sugar bite. Choose dairy-free chips if needed. Melted with the peanut butter, this chocolate forms the base that holds these 3 ingredient no bake cookies together.
Optional extras: A splash of vanilla, a pinch of cinnamon, or a handful of shredded coconut can change the vibe without changing the method.
How to Make 3 Ingredient No Bake Cookies Step by Step
This method is fast, forgiving, and friendly for all skill levels—even preschool helpers can get involved.
- Toast your oats. Spread them on a baking sheet and toast at 350°F for 12 minutes, stirring halfway. Let cool slightly before mixing.
- Melt the chocolate and peanut butter. Add both to a saucepan over medium heat. Stir until melted and smooth, then remove from heat.
- Mix in the oats. Add the toasted oats to the warm chocolate-peanut butter blend. Stir quickly and evenly—this is when your 3 ingredient no bake cookies start taking shape.
- Scoop and press. Use a spoon or cookie scoop to portion dough onto a parchment-lined tray. Gently flatten with oiled fingers.
- Chill to set. Freeze for 15 minutes or refrigerate for 2–3 hours. Store extras in a sealed container in the fridge—they’ll last for weeks (if they don’t get eaten first).

Variations & Troubleshooting for Perfect 3 Ingredient No Bake Cookies
The beauty of 3 ingredient no bake cookies is how simple they are. But like any recipe, a batch can go sideways if the texture’s off or the ingredients aren’t quite right. The good news? It’s super easy to fix. Below, I’ll walk you through the most common issues I see (and face myself), and share some of our favorite add-ins—especially ones that toddlers go wild for.
Why Don’t My 3 Ingredient No Bake Cookies Harden?
This is the question I get the most. If your cookies aren’t firming up, it’s usually one of three reasons:
- Dry peanut butter. If your peanut butter is too thick, your dough won’t bind well. You need it soft and drippy. If it’s too dry, add a tablespoon of melted coconut oil or maple syrup to loosen it up.
- Too little oats. These cookies rely on oats for structure. If your mix is too wet, try adding 2–3 tablespoons of extra oats at a time until it firms up.
- Not enough chill time. Pop your 3 ingredient no bake cookies in the freezer for at least 15 minutes—or longer in the fridge if your kitchen is warm.
If you’re craving something even richer, try our no bake chocolate pie—it’s creamy, dreamy, and just as oven-free.

FAQs About 3 Ingredient No Bake Cookies
How to make 3-ingredient brownie cookies?
Brownie-style no bake cookies usually swap oats for almond flour or crushed walnuts for a dense, fudgy texture. Mix ½ cup peanut butter, ½ cup melted dark chocolate, and ¼ cup almond flour until thick. Scoop and chill. They’re rich, chewy, and taste like brownies with none of the oven wait.
Why do my no bake cookies never harden?
If your 3 ingredient no bake cookies stay soft, it’s often due to thick peanut butter or not enough oats. Use runny peanut butter, toast your oats, and don’t skip the chill time. A freezer session (15–20 minutes) helps them set faster than just refrigeration.
What are the three ingredients for sugar cookies?
Classic 3-ingredient sugar cookies usually include all-purpose flour, butter, and granulated sugar. Unlike no-bake cookies, these do require baking and result in a crisp, buttery texture. Not to be confused with our chewy, oat-based no-bake version.
What are the three ingredient toddler cookies no bake?
