Ingredients You’ll Need
These ingredients are wonderfully simple but each plays a vital role in creating the perfect balance of textures and flavors in your Peanut Butter Oat Cups. From the creamy richness of peanut butter to the chewy wholesomeness of oats and the subtle sweetness of maple syrup, every component shines.
- Peanut butter (2/3 cup): Use natural or creamy peanut butter to add that rich, nutty base that defines the flavor.
- Old fashioned (rolled) oats (3/4 cup): They provide hearty texture and keep the cups wholesome and filling.
- Maple syrup (2 tbsp): Adds a lovely natural sweetness that perfectly balances the saltiness of peanut butter.
- Peanut butter for topping (1 tbsp per cup): A smooth dollop or mixed with protein powder gives an extra punch of flavor and creaminess on top.
- Peanut butter (1/2 cup): Additional amount for the protein topping mixture, making it extra decadent.
- Protein powder (3 tbsp): Optional but fantastic for boosting the nutritional value without compromising taste.
- Chocolate chips (1 cup, melted): Melted dark chocolate adds that luxurious, chocolatey finish everyone loves.
- Flakey sea salt (optional): Just a pinch on top to elevate all the flavors and add a little contrast.
How to Make Peanut Butter Oat Cups
Step 1: Mix Peanut Butter and Maple Syrup
Start by combining the peanut butter and maple syrup in a bowl. This blend creates a smooth, sweet, and nutty base that binds everything together and sets the tone for the rest of the Peanut Butter Oat Cups.
Step 2: Add the Oats
Next, stir in the rolled oats until the mixture is well combined. The oats give a lovely texture and substance, making these cups satisfying and hearty enough to keep you energized.
Step 3: Form the Base
Spoon the oat mixture into silicone molds, pressing down evenly for a compact base. Using a cookie scoop to portion about 2 tablespoons per cup works perfectly for even-sized treats that will hold their shape beautifully.
Step 4: Add the Topping
Add a dollop of plain peanut butter to each cup or combine peanut butter with protein powder for an extra nutritious topping spread. This layer adds creaminess and gives a nice textural contrast once frozen.
Step 5: Freeze the Cups
Pop the molds into the freezer for around 20 minutes to let everything firm up just right, so your cups will easily hold their shape when you add the finishing touches.
Step 6: Melt the Chocolate
Melt your chocolate chips in the microwave with a splash of oil, heating in 30-second intervals and stirring each time to avoid burning. This ensures a silky, glossy chocolate perfect for drizzling.
Step 7: Finish with Chocolate and Freeze
Pour or spoon your melted chocolate over the top of each peanut butter oat cup, then return them to the freezer for another 20 minutes until set. This final freeze locks in all the layers and results in a dreamy texture that’s both creamy and crunchy.
Step 8: Serve and Sprinkle with Sea Salt
Once ready, remove your Peanut Butter Oat Cups from the silicone molds, sprinkle with flakey sea salt if you like, and enjoy an irresistible bite that combines sweet, savory, and nutty notes beautifully.
How to Serve Peanut Butter Oat Cups

Garnishes
Adding a sprinkle of flakey sea salt on top of the chocolate not only looks pretty but enhances the rich flavors beneath. For extra flair, sprinkle with crushed peanuts or a dusting of cocoa powder for a little pizzazz.
Side Dishes
These cups are perfect alongside a hot cup of coffee or tea for a mid-afternoon pick-me-up. Pair them with fresh fruit like sliced bananas or berries, which bring a refreshing natural sweetness to balance the richness.
Creative Ways to Present
Try layering your Peanut Butter Oat Cups in a decorative jar or gifting them in small boxes wrapped with twine. They also make excellent snack bites during gatherings—arranged on a pretty platter, they’re guaranteed to be a crowd-pleaser.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Peanut Butter Oat Cups in an airtight container in the refrigerator. They stay fresh for up to a week while maintaining their texture and flavor, making them a perfect ready-made snack.
Freezing
For longer storage, freeze the cups in a sealed container or freezer bag. They keep well for up to two months and can be enjoyed straight from the freezer or thawed in the fridge for a softer bite.
Reheating
These peanut butter oat cups don’t need traditional reheating but left at room temperature for a few minutes, they soften slightly and release their full flavor. Avoid microwaving as it can alter the texture of the chocolate and peanut butter layers.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter adds an extra layer of texture that complements the oats well. Just keep in mind it might make the mixture a little chunkier.
Is there a way to make these cups vegan?
Yes, choose vegan dark chocolate chips and ensure your protein powder is plant-based. The rest of the ingredients are naturally vegan, so it’s an easy switch.
Can I substitute maple syrup with another sweetener?
Sure! Honey or agave syrup works great as alternatives. Maple syrup adds a unique flavor, but these substitutes will also provide the necessary sweetness and binding.
What protein powder works best in these cups?
Whey protein blends well, but if you prefer plant-based options, pea or soy protein powders are excellent choices that won’t overpower the peanut butter flavor.
Can I make these without protein powder?
Definitely! The protein powder is optional and mainly boosts nutritional content. The cups are delicious and satisfying even without it.
Final Thoughts
The joy of these Peanut Butter Oat Cups is their simplicity combined with truly satisfying flavors. They’re the kind of snack you’ll find yourself making again and again, whether for a quick morning boost, a post-workout treat, or a little sweet indulgence any time of day.
