Prepare the Peanut Butter Filling: In a large mixing bowl, beat together the creamy peanut butter and softened butter until smooth and well combined. Gradually add the powdered sugar and vanilla extract, mixing until the mixture is thick and smooth.

Shape the Hearts: If you’re using heart-shaped silicone molds, press the peanut butter mixture into the molds, smoothing the tops with a spatula. If you’re using cookie cutters, press the peanut butter mixture into a 1/2-inch thick layer on a parchment-lined baking sheet, and then use the cookie cutters to cut out heart shapes. Place the hearts on the baking sheet.

Chill the Hearts: Transfer the peanut butter hearts to the freezer and chill for about 30 minutes, or until firm.

Melt the Chocolate: In a microwave-safe bowl, melt the semi-sweet chocolate chips or chocolate candy melts in 30-second intervals, stirring between each interval, until the chocolate is fully melted and smooth.

Coat the Hearts: Remove the peanut butter hearts from the freezer. Using a fork, dip each heart into the melted chocolate, making sure it’s fully coated. Allow any excess chocolate to drip off before placing the hearts back on the parchment-lined baking sheet.

Set the Chocolate: Let the chocolate-coated hearts set at room temperature or place them in the refrigerator until the chocolate is firm.

Serve and Enjoy: Once the chocolate is set, your Chocolate Peanut Butter Valentine’s Hearts are ready to be enjoyed. These sweet treats are perfect for sharing with loved ones or as a special Valentine’s Day gift.
