• Unsalted creamy peanut butter (for topping) – Enhances creaminess; adjust the quantity for a lighter topping.
Step‑by‑Step Instructions for No-Bake Peanut Butter Oat Cups
Step 1: Prepare the Muffin Tin
Start by lining a muffin tin with 10 to 12 paper liners for easy removal, or lightly grease it with coconut oil to prevent sticking. This step is essential as it creates the perfect vessel for your No-Bake Peanut Butter Oat Cups, allowing them to maintain their shape as they chill.
Step 2: Mix the Peanut Butter and Maple Syrup
In a mixing bowl, combine 8 tablespoons of creamy peanut butter with 6 tablespoons of maple syrup. Stir the mixture vigorously with a spatula for about 1 to 2 minutes until it becomes smooth and glossy. This creamy blend is the foundation of your oat cups, adding both flavor and sweetness.
Step 3: Incorporate the Rolled Oats
Next, add 1 and 3/4 cups of rolled oats to the peanut butter mixture. Stir until the oats are fully coated, which should take just a minute or two. The oats will absorb the moisture and flavor, providing a hearty base for your No-Bake Peanut Butter Oat Cups that will hold together beautifully.
Step 4: Fill the Muffin Liners
Take about 2 tablespoons of the oat mixture and distribute it evenly into each muffin liner, pressing down firmly to pack it tightly. Ensure that the bases are well-formed and compact to maintain their structure once chilled. This step is crucial for achieving that perfect chewy texture.
Step 5: Chill the Oat Base
Place the muffin tin in the refrigerator and chill the oat bases for about 15 to 20 minutes. This will allow them to firm up, providing a sturdy bottom layer for your No-Bake Peanut Butter Oat Cups. Keep an eye on them—they should be firm to the touch when ready to layer with chocolate.
Step 6: Melt the Chocolate and Peanut Butter Topping
In a microwave-safe bowl, combine 1/2 cup of vegan chocolate chips and 5 tablespoons of creamy peanut butter. Heat the mixture in 20-second intervals, stirring in between, until it’s completely smooth—this should take about a minute. This luscious chocolate layer will perfectly combine with the nutty flavor.
Step 7: Top Each Oat Cup
Spoon 1 to 2 teaspoons of the melted chocolate and peanut butter mixture over each oat base, making sure to smooth the tops for an even finish. The chocolate topping not only adds flavor but also elevates your No-Bake Peanut Butter Oat Cups to a delightful treat.
Step 8: Freeze Until Firm
Transfer the muffin tin to the freezer and let the cups chill for 20 to 30 minutes. This will set the chocolate topping and solidify the cups, ensuring a deliciously satisfying bite. You’ll know they are ready when the chocolate is hard and the cups feel firm to the touch.
Step 9: Remove and Serve
Once set, gently remove the cups from the muffin tin and peel off the liners. Allow them to sit at room temperature for about 5 minutes before serving. This brief wait allows the No-Bake Peanut Butter Oat Cups to soften slightly, making them delectable and easy to enjoy!

Store your oat cups in an airtight container in the fridge for up to 10 days. This keeps them fresh and ready for a delicious snack!
