3 Ingredient No Bake Peanut Butter Oat Cups
These 3 Ingredient No Bake Peanut Butter Oat Cups are soft, chewy, and ridiculously easy, and yes, you can eat the dough straight from the bowl. The whole batch comes together in about 15 minutes with no baking and no cooking at all.
No oven, no stove, and no waiting around for anything to cool. Just three simple ingredients, one bowl, and a mini cup pan.
They belong to the same easy family as the other few ingredient no bake treats on this site: peanut butter granola, peanut butter oatmeal cookies, no bake oatmeal cookies, no bake chocolate oatmeal cookies, energy balls, peanut butter blondies, oatmeal cookie bars, no bake peanut butter coconut balls, and cereal bars.
What they all share is the same simple appeal. Very few ingredients, quick and easy prep, and snacks that are genuinely convenient to grab and go.
This cups version grew out of a January recipe plan. The original post explains that the goal was to create the easiest recipes with the fewest ingredients for the no bake collection, and that readers responded so well to the blog’s no bake cookies that a cups version was the obvious next step.
If you like having the full walkthrough in one place, the No Bake Peanut Butter Oat Cups Recipe covers this treat from start to finish.
What you end up with is a soft, chewy cup with a peanut butter forward flavor and just enough sweetness from the maple syrup. They hold together well enough for a lunchbox or a tote bag, and they taste like a real treat rather than a compromise.

Easy No Bake Peanut Butter Oatmeal Cookie Cups
After the no bake cookies did well, a cups version was created and the recipe was tweaked so it would carry a little more moisture with fewer dry ingredients. Fewer oats, specifically. That small change makes the dough much easier to scoop and mold, so the cups come out neat and tender instead of dry and crumbly.
The result is a peanut butter oatmeal cookie cup, or, if you want the long official name, 3 Ingredient No Bake Peanut Butter Oatmeal Cookie Cups (Healthy). Same three ingredients either way, and the same short list of steps.
Because the dough stays soft and scoopable, it also works with shaped molds. Press it into hearts, dinosaurs, or any small silicone mold you have on hand, and you get a completely different look from the exact same bowl of dough. That is a fun one to hand over to kids, and it turns a snack into a little project.
This treat also lives comfortably next to the rest of the collection. The 3 Ingredient No Bake Peanut Butter Oat Cups page gathers the same recipe and the related no bake ideas in one spot, which is handy when you want to plan a whole snack tray at once.
Only 3 Ingredients for Delicious Peanut Butter Oatmeal Cups
Three ingredients. That is the whole list, and nothing is hiding in the back of the pantry.
- Natural, creamy peanut butter, or homemade peanut butter if you have it.
- Gluten free rolled oats.
- Pure maple syrup.
The amounts are 1 cup smooth peanut butter, 1/4 cup plus 2 tablespoons pure maple syrup, and 1 3/4 cups gluten free rolled oats. That makes 34 mini cups, which sounds like a big batch until you watch them disappear.
A few notes on shopping. Look for unsalted natural creamy peanut butter, gluten free rolled oats, and pure maple syrup. The peanut butter does most of the heavy lifting for flavor, so a brand you actually enjoy makes a real difference. For a gluten free version, use oats that are labeled gluten free.
If peanut butter desserts are your thing, the peanut butter blondies and the oatmeal cookie bars on this site are good next stops once you have made a batch or two of these cups.
How to Make No Bake Peanut Butter Oatmeal Cookie Cups
This is the kind of recipe you can make on a weeknight when you want something sweet and have zero patience. Everything happens in one bowl, plus a pan for chilling.
- Lay a 24 mini cup silicone baking pan on a medium baking sheet. A mini pan is strongly recommended here, because it makes removing the oat cups much easier. Set it aside for later.
- In a large microwave safe bowl, add the peanut butter and the maple syrup. Whisk together until well mixed.
- Heat in 20 second increments in the microwave until the mixture is warm and fragrant and begins to dry out, about 4 to 7 rounds. Whisk in between every heating increment. This is also the stage where the mixture turns fluffy, so keep an eye on it.
- Add the oats to the peanut butter mixture. Use a rubber spatula or a wooden spoon to fold until thoroughly combined. A silicone spatula works well here. What you have now is a no bake oatmeal cookie dough, and it is completely fine to eat right out of the bowl.
- Using a small cookie scoop, scoop and drop balls of dough into the cups of the baking pan. Then use a spoon to press and flatten the mixture until the tops are smooth and the dough is evenly distributed in each cup. Any extra dough can go into another pan, or you can use it to make thicker cups.
- Chill in the freezer for 15 to 25 minutes, until firm. Enjoy.
One optional twist: skip the flattening step and you get peanut butter oat balls instead of cups. Same dough, different shape, and just as good.
Stovetop option. If you would rather not use a microwave, add the peanut butter and the maple syrup to a medium saucepan over medium low heat. Whisk until well incorporated, stir occasionally, and heat until the mixture begins to bubble.
Remove from heat and carefully pour it over the oats. This is an alternative to the microwave steps, not a replacement for the chilling step.
Storage. Keep the cups in an airtight container in the refrigerator or at room temperature for up to 1 month. After the first day they can be stored at room temperature and they will be a bit more firm.
For freezing, store them in a freezer friendly container or bag for 1 to 2 months, and let them thaw at room temperature for 5 to 15 minutes before enjoying.
The flattening step is what turns dough balls into cups. Skip it on purpose if you want bite sized oat balls instead.

This recipe is adapted from a 3 ingredient peanut butter granola bars recipe, and the original version is the 3 Ingredient No Bake Peanut Butter Oatmeal Cookie Cups recipe. If you want more no bake snacking ideas, the no bake peanut butter coconut balls and the customizable cereal bars are two easy places to go next.
Best Tools for Easy No Bake Peanut Butter Oatmeal Cookie Cups
You can absolutely make these with a bowl and a spoon, but a couple of tools make the process smoother and the cups tidier.
The large and mini cup pan set is the standout. It includes both a regular cup pan and a mini cup pan, and the mini one is the pan used for this recipe and its photos.
The cups popped right out of the pan, and the pan was easy to clean, which matters more than you would expect with sticky dough.
Compostable snack bags are the other favorite. They came out of a long search for compostable snack bags, and they get used constantly to store snacks in the freezer, to bring large quantities of nuts and bars while traveling, and for everyday use.
- Silicone large and mini cup pan set, with the mini pan being especially helpful
- Glass mixing bowls
- Prep bowls for portioning oats, peanut butter, and maple syrup
- A small cookie scoop for even cups
- Compostable snack bags for storage and travel
- A rubber spatula or a wooden spoon for folding
Two small things that make a difference. A cookie scoop keeps every cup the same size, so they all firm up at the same rate in the freezer. And placing the silicone pan on a baking sheet before you start means you can move the whole thing to the freezer in one trip without the pan flexing and dropping dough.
Where to buy the ingredients: unsalted natural creamy peanut butter, gluten free rolled oats, and pure maple syrup. Those three items are the entire shopping list, which is a big part of why this recipe stays in rotation.

FAQs
Can I use conventional peanut butter instead of natural creamy peanut butter?
You can, but the cups will turn out softer. Natural creamy peanut butter made from peanuts and salt gives the firmest results once chilled, while conventional peanut butter with added oils and sugar stays softer and can be harder to unmold. Stir natural peanut butter thoroughly before measuring, since the oil separates on the shelf. This recipe uses 1 cup smooth peanut butter.
Do I have to use a microwave to make peanut butter oat cups?
No, a stovetop version works just as well. In the microwave, whisk 1 cup smooth peanut butter with 1/4 cup plus 2 tablespoons pure maple syrup and heat in 20-second increments, whisking between rounds, for about 4 to 7 rounds until warm and fragrant. On the stovetop, whisk the same amounts in a medium saucepan over medium-low heat until the mixture begins to bubble, then remove from heat and pour it over the oats.
How long do no bake peanut butter oat cups last, and how should I store them?
Keep the cups in an airtight container in the refrigerator or at room temperature for up to 1 month. After the first day they can be stored at room temperature, where they become more firm. For longer storage, freeze them in a freezer-friendly container or bag for 1 to 2 months, then let them thaw at room temperature for 5 to 15 minutes before eating.
Can I use quick oats or steel-cut oats instead of rolled oats?
Rolled oats, also labeled old-fashioned oats, are the right choice because they give the classic soft and chewy bite. Quick oats absorb moisture faster and produce a softer, more porridge-like cup, while steel-cut oats stay too hard to eat in a no bake recipe. The recipe calls for 1 3/4 cups gluten free rolled oats.
