Directions: Keto Peanut Butter Cups

Let’s get started with making these delightful Keto Peanut Butter Cups!
Step 1: Prepare Your Muffin Tin
Line a muffin tin with parchment paper liners. This step is crucial to ensure your peanut butter cups come out easily and maintain their shape.
Step 2: Melt the Chocolate
In a microwave-safe bowl, combine the keto chocolate chips or chopped sugar-free chocolate bar with the coconut oil. Microwave in 30-second intervals, stirring in between, until completely melted and smooth.
Step 3: Create the Chocolate Layer
Spoon about 1 tablespoon of the melted chocolate into each muffin liner. Use the back of your spoon to spread it evenly across the bottom of the liner. Place the muffin tin in the freezer for about 10-15 minutes to set.
Step 4: Add the Peanut Butter Filling
Once the chocolate layer has hardened, remove the muffin tin from the freezer. Next, add about 1 tablespoon of the smooth, drippy peanut butter into each liner on top of the hardened chocolate.
Step 5: Top with More Chocolate
Pour another tablespoon of the melted chocolate over the peanut butter layer, making sure to fully cover it. You want your cups to be sealed with chocolate on top!
Step 6: Final Freeze
Return the muffin tin to the freezer for an additional 15-20 minutes, or until the chocolate is completely set.
Step 7: Enjoy!
Once the chocolate is firm, carefully peel away the parchment paper liners to enjoy your homemade Keto Peanut Butter Cups. Store them in an airtight container in the fridge for the best texture.
If You’re Out Of…

Don’t worry if you find yourself missing an ingredient! Here are some substitutions:
- Coconut oil: You can use unsalted butter instead, though the flavor will be slightly different.
- Keto chocolate chips: Dark chocolate can work as a substitute, but be sure to check the sugar content.
- Peanut butter: Almond butter or cashew butter can make for delicious alternatives.
- Parchment liners: Silicone muffin cups are a great reusable option if you don’t have liners on hand.
Flavor Logic
The beauty of these Keto Peanut Butter Cups lies in their simplicity and flavor harmony. The combination of rich, creamy peanut butter and the satisfying crunch of chocolate creates a textural contrast that keeps each bite exciting.
- Chocolate: The sugar-free chocolate melts beautifully and provides a sweet, slightly bitter taste that complements the peanut butter.
- Peanut Butter: Smooth and drippy, the peanut butter adds a nutty flavor and a creamy texture that balances the richness of the chocolate.
- Coconut Oil: This adds a hint of tropical flavor while helping the chocolate to set perfectly.
Keep It Fresh: Storage Guide
To maintain the freshness of your Keto Peanut Butter Cups, follow these storage tips:
- Store in an airtight container in the refrigerator to keep them firm and fresh.
