Step‑by‑Step Instructions for Peanut Butter Oat Cups
Step 1: Combine Ingredients
In a mixing bowl, blend together 1 cup of creamy peanut butter and 1/3 cup of maple syrup until the mixture is smooth and well combined. Use a rubber spatula for easy mixing, ensuring there are no lumps. This step sets the foundation for your Peanut Butter Oat Cups, creating a creamy and sweet base that’s simply irresistible.
Step 2: Add Oats
Once your peanut butter and maple mixture is smooth, stir in 2 cups of old-fashioned rolled oats. Mix thoroughly until all the oats are evenly coated, creating a thick, sticky mixture. This combination provides texture and fiber to the cups. The mixture should be cohesive and slightly sticky, perfect for shaping into your oat cups.
Step 3: Mold the Mixture
Spoon the oat mixture into silicon molds, filling each mold about 3/4 full. Use the back of a spoon to press the mixture down firmly, ensuring it holds its shape. This step is crucial for forming your Peanut Butter Oat Cups, as it will help them maintain their structure once set.
Step 4: Add Peanut Butter Filling
After molding, take additional peanut butter and place a generous dollop on top of each cup. For a protein boost, you can mix in a scoop of protein powder with the peanut butter. This filling enhances flavor and adds richness to the overall taste, making your treats even more satisfying to enjoy.
Step 5: Freeze to Set
Place the filled molds in the freezer for about 20 minutes. This will help the Peanut Butter Oat Cups firm up nicely, creating a perfect texture. Keep an eye on them; they should be set but not rock-solid. This freezing step is key to achieving the ideal consistency for snacking.
Step 6: Melt the Chocolate
While the cups are freezing, melt 1 cup of chocolate chips in a microwave-safe bowl. Heat in increments of 20 seconds, stirring in between to avoid burning. Once melted, you can add a teaspoon of oil to give the chocolate a glossy finish that drizzles beautifully over your cups.
Step 7: Drizzle Chocolate
Once the cups are firm, remove them from the freezer and drizzle the melted chocolate over each oat cup using a spoon or a piping bag for precision. The warm chocolate will form a beautiful coating, adding richness to your Peanut Butter Oat Cups. Let the chocolate set for a few moments before proceeding to the next step.
Step 8: Final Freeze
Return the cups to the freezer for another 20 minutes, allowing the chocolate to harden completely. This ensures your treats stay well-formed and easy to handle. After this time, they will be ready to pop out of the molds and showcase their delightful layers of flavor and texture.
Step 9: Serve & Enjoy
Once fully set, carefully remove the Peanut Butter Oat Cups from the molds. If desired, sprinkle a pinch of flaky sea salt on top for a touch of sophistication. These delightful, chewy snacks are now ready to be enjoyed—perfect for a quick bite or a healthy treat anytime!

Absolutely! For the best flavor and texture, select natural, creamy peanut butter without added sugars or oils. Look for old-fashioned rolled oats that have a nice chewy texture, and ensure they’re not stale. Fresh maple syrup enhances the sweetness, so check that it’s pure and free of additives.
How should I store my Peanut Butter Oat Cups?
You can keep your Peanut Butter Oat Cups in an airtight container in the fridge for up to 3 days, which will keep them nice and chewy. If you prefer them firmer, store them in the freezer for up to 2 months. Just remember to thaw them slightly at room temperature for a few minutes before enjoying!

What should I do if my mixture is too sticky or crumbly?
If your mixture seems too sticky, it may be due to runny peanut butter. Try adding a bit more rolled oats to help absorb the moisture. On the other hand, if it’s too crumbly, you can add a little more maple syrup or additional peanut butter until it reaches a cohesive, moldable consistency.
Are there any dietary considerations when making these Peanut Butter Oat Cups?
Very! These cups are naturally gluten-free if you use certified gluten-free oats. For nut-free options, substitute peanut butter with sunflower seed butter. Always check for allergies, especially with ingredients like chocolate or protein powder, and opt for dairy-free chocolate if needed to keep them vegan.
Can I adjust the sweetness of the Peanut Butter Oat Cups?
Of course! If you find the cup mixture is too sweet for your taste, feel free to reduce the amount of maple syrup slightly. You can also experiment by adding unsweetened cocoa powder to balance the sweetness, or enjoy them plain without the chocolate coating for a less sweet option!
