Prepare your workspace and gather all the ingredients.
Melt the chocolate chips in a microwave-safe bowl.
Spoon a small amount of the melted chocolate into each cupcake liner.
Place the chocolate-lined cups in the freezer for about 10 minutes.
Combine the peanut butter, powdered sugar, vanilla extract, and sea salt in a bowl.
Spoon the peanut butter mixture over the set chocolate in each liner.
Melt any remaining chocolate and cover the peanut butter filling in each cup.
Return the filled cups to the freezer for an additional 15 minutes to set.
Once set, carefully remove the chocolate cups from their liners and enjoy!
