Step‑by‑Step Instructions for Peanut Butter Oat Cups
Step 1: Mix Peanut Butter & Maple Syrup
In a medium bowl, combine 1 cup of creamy peanut butter and 1/3 cup of maple syrup. Use a spatula to mix them until smooth and well incorporated. You should see a glossy, cohesive mixture without any lumps. This flavorful base brings together the nuttiness of peanut butter with the sweetness of maple syrup.
Step 2: Incorporate Oats
Next, add 2 cups of old-fashioned rolled oats into the peanut butter mixture. Stir vigorously until the oats are fully coated and evenly distributed throughout the mixture. The texture should resemble a sticky, thick dough, ensuring that every oat is enveloped in the peanut buttery goodness. This is the foundation for your Peanut Butter Oat Cups.
Step 3: Shape Oat Cups
Spoon the mixture into silicone molds, filling each one about two-thirds full. Use the back of a spoon to press down firmly, creating an even base for each cup. Ensure the mixture is packed tightly so that the cups hold their shape once frozen. This step is crucial for achieving the perfect form and texture when you pop them out.
Step 4: Top with Peanut Butter
Optionally, you can add a dollop of additional peanut butter on top of each filled mold. If you want a protein boost, mix a scoop of protein powder into the extra peanut butter before spreading it on top of the cups. This layer not only enhances the flavor but also adds a delightful creaminess to every bite of your Peanut Butter Oat Cups.
Step 5: Freeze Base
Transfer the filled silicone molds to the freezer and allow them to set for about 20 minutes. You’ll know they’re ready when they feel firm and hold their shape. This step is essential for setting the oat mixture, making it easy to add the chocolate topping without it sliding off.
Step 6: Melt Chocolate
While the oat cups are firming up, melt 1 cup of chocolate chips with a teaspoon of oil in a microwave-safe bowl. Heat in 30-second intervals, stirring between each interval until smooth and fully melted. Be careful not to overheat. The melted chocolate should have a luscious, glossy consistency perfect for drizzling over your Peanut Butter Oat Cups.
Step 7: Add Chocolate Topping
Once the oat bases are set, drizzle the melted chocolate generously over each cup. Use a spoon or a piping bag for precise drizzle patterns. This layer of chocolate will add a delightful sweetness and a beautiful finish to your cups, making them even more irresistible.
Step 8: Final Freeze
Return the filled molds to the freezer for an additional 20 minutes to allow the chocolate to set completely. They should feel firm to the touch and be easy to peel from the molds once ready. This final freeze ensures that every component of your Peanut Butter Oat Cups is perfectly integrated and ready to enjoy.
Step 9: Serve
Carefully remove the Peanut Butter Oat Cups from the molds. If desired, sprinkle a pinch of flaky sea salt on top to enhance the flavors. These delightful cups can be served immediately or stored in an airtight container in the fridge or freezer for later. Enjoy the chewy, creamy goodness of your homemade Peanut Butter Oat Cups!

Peanut Butter Oat Cups Recipe FAQs
What type of peanut butter should I use?
Absolutely! For the best results, use creamy peanut butter, as it mixes smoothly into the oat mixture. Natural peanut butter can work too, but it may have oil separation and can take longer to freeze. If you’re looking for nut-free options, sunflower seed butter or almond butter are delicious alternatives that maintain the great taste.
How long can I store these oat cups in the fridge?
You can keep your Peanut Butter Oat Cups in an airtight container in the refrigerator for up to 7 days. They’ll be wonderfully soft and chewy—a perfect snack to satisfy your cravings during the week! Just remember, if you do keep them in the fridge for too long, check for any dark spots or off smells before enjoying.
Can I freeze my Peanut Butter Oat Cups?
Certainly! For long-term storage, place the oat cups in a freezer-safe bag or container for up to 3 months. Make sure to separate layers with parchment paper to prevent sticking. When you’re ready to enjoy them, allow the cups to sit at room temperature for a few minutes to soften slightly before eating. This will help retain their delightful texture!
What should I do if my mixture is too dry?
If you find that the mixture is crumbly or too dry, don’t fret! Simply add a touch more peanut butter or a splash of plant-based milk to achieve the desired consistency. Mix thoroughly until everything is well combined. Remember, the mixture should be thick yet cohesive enough to hold together once pressed into the molds.
Are these oat cups safe for people with nut allergies?
Great question! While traditional recipes use peanut butter, you can easily make these Peanut Butter Oat Cups nut-free by substituting peanut butter with sunflower seed butter. Just make sure to also check any other ingredients for potential allergens. These adaptations will ensure everyone can enjoy these delicious treats without worries!
