Easy "Reese's" Dupes (Kids & Protein Versions)

For the kid-friendly version: Melt semi-sweet dark chocolate chips in the microwave for about 90–120 seconds, stirring every 30 seconds or so until smooth. In a separate bowl, melt natural peanut butter or sunflower butter in the microwave for about 60 seconds. Layer the melted chocolate and melted nut or seed butter in silicone molds, then pop them in the freezer until set. 

For a more protein-focused version: Mix peanut powder with stevia and water in approximately a 1:1 ratio to form a paste. Layer this mixture with the melted chocolate in silicone molds and freeze until firm.
