Begin by placing the chocolate chips in a microwave-safe bowl. Melt them in the microwave for 90 seconds, stirring halfway through until completely smooth. This method ensures that the chocolate melts evenly and doesn’t burn.
Prepare your mini muffin tin by placing small paper liners into each compartment. Once the chocolate is melted, take 1 heaping teaspoon of the melted chocolate and pour it into the lined muffin cups. Use the back of a spoon to spread the chocolate evenly across the bottom. Transfer the tin to the refrigerator for at least 10 minutes to set.
While the first layer of chocolate is cooling, take a medium bowl and combine the peanut butter and powdered sugar. Stir them together until well mixed. This creates a creamy mixture that will form the filling for your cups.
Once the chocolate layer has set, it's time to form the filling. Roll 1 teaspoon of the peanut butter mixture into a ball, and then flatten it into a disk. This shape will fit perfectly on top of the chocolate base. Repeat the process with the remaining peanut butter mixture.
After you’ve formed all the disks, take the muffin tin out of the refrigerator. Place one peanut butter disk in each cup on top of the chilled chocolate. Make sure the disks are centered and touching the edges of the chocolate.
Pour the remaining melted chocolate over the top of each peanut butter disk, ensuring that it is completely covered. This will create a beautiful shell that encases the tasty filling.
Finish by sprinkling a few flakes of Maldon sea salt over the top of each cup. This step adds a gourmet touch and enhances the overall flavor experience.
Return the muffin tin to the refrigerator until the chocolate has completely set. This usually takes about 30 minutes. You’ll know they’re ready when the chocolate feels firm to the touch.
Once set, carefully peel the cups from the paper liners. Take your time to ensure that the chocolate doesn’t break apart. Each cup should come out easily.
