Crumbly peanut marzipan discs that melt on your tongue are an iconic Mexican candy. This family-favorite treat is a delicate, sweet, protein-rich confection loved by all ages.
Add roasted peanuts and powdered sugar to a food processor and pulse until a very fine, sandy mixture forms; do not over-process or allow nut oil separation.
Add vanilla extract and pinch of salt, then pulse briefly to incorporate; stop as soon as ingredients are blended evenly.
Line a flat workspace with parchment paper and prepare a round cutter or small mold.
Firmly press the mixture into your mold or cutter, packing tightly for each disc; gently lift out to retain shape.
Allow discs to sit uncovered for 10 minutes, so powdery edges dry and set before serving or wrapping. Handle with care to prevent crumbling.
