Description

A rich, creamy peanut butter fudge loaded with M&Ms — sweet, salty, and totally irresistible.


Ingredients

  • ½ cup (113 g) unsalted butter
  • 1 cup (250 g) creamy peanut butter
  • 3 cups (360 g) powdered sugar, sifted
  • 1 teaspoon vanilla extract
  • Pinch of salt (about 1⁄8 teaspoon)
  • 1 cup (170 g) mini M&Ms, plus extra for topping

Instructions

  1. Line an 8‑inch (20 cm) square baking pan with parchment paper, allowing some overhang for easy removal.
  2. In a medium saucepan over low heat, melt the butter until fully liquid.
  3. Remove from heat and stir in the peanut butter until smooth and fully combined with the melted butter.
  4. Add the vanilla extract and salt, stirring to combine.
  5. Gradually whisk in the sifted powdered sugar until the mixture becomes thick and fudge‑like.
  6. Fold in 1 cup of mini M&Ms, then spread the mixture evenly into the prepared pan, pressing gently with a spatula to smooth the top.
  7. Sprinkle a few extra mini M&Ms on top for decoration and a fun crunch.
  8. Refrigerate for at least 2 hours (or until firm) before cutting into small squares.
  9. Once firm, lift the fudge out using the parchment overhang and cut into about 36 squares. Store in an airtight container in the fridge.

Notes

  • For a chocolate‑peanut butter twist, you can swirl in ½ cup of melted semi‑sweet chocolate before refrigerating.
  • Let fudge sit at room temperature for 5–10 minutes before eating for a softer, creamier texture.
  • Because of the powdered sugar and candy, this fudge is quite sweet — adjust sweetness by reducing sugar by ¼ cup if desired.
  • Keep stored in the fridge — fudge may soften too much at room temperature.
