Peanut Butter Rocky Road Bars

  • Author: Jenna Barnard
  • Total Time: 1 hour 30 minutes
  • Yield: 15 bars


These rocky road bars are so fudgy and loaded will all the best mix-ins! Fluffy marshmallows, crunchy salted pretzels, sweet candy coated chocolates, and a layer of peanut butter cups make up this incredibly delicious but easy recipe.


Peanut Butter Rocky Road Bars

  • 12 oz bag dark chocolate chips
  • 3 tbsp (40g) refined coconut oil or unsalted butter
  • 3/4 cup (200g) creamy peanut butter
  • 2 heaping cups mini marshmallows
  • 1 heaping cup pretzels, roughly broken up (regular or gluten free)
  • 1/2 cup M&M’s (plus more for decoration)
  • 12 mini Reese’s Christmas trees (or your preferred peanut butter cup)
  • Sprinkles, for decoration


Peanut Butter Rocky Road Bars

  1. Fill a medium pot with a couple inches of water and place over medium heat.
  2. In a heat-safe bowl, add the dark chocolate chips, coconut oil, and peanut butter.
  3. Place the bowl over the pot of simmering water (ensuring the bowl doesn’t touch the water) and stir to slowly melt.
  4. Once smooth, remove from heat and set aside to cool for about 10 minutes.
  5. In the meantime, grease the inside of an 8×8 pan. Line the bottom and two sides with a sheet of parchment paper and allow the paper to hang over the sides for easy removal.
  6. To the melted chocolate, add the marshmallows, pretzels, and M&M’s and stir to coat.
  7. Pour half of the mixture into the pan. Spread and pat down the mixture and then tap the pan against the counter a couple times to help condense everything.
  8. Nestle in a layer of the peanut butter cups. This doesn’t have to be perfect, just place them equal distances apart from each other.
  9. Pour the remaining mixture on top and spread even. Tap the pan again to make sure the mixture is really packed down in there.
  10. Top with some extra M&M’s and sprinkles and pop the pan into the refrigerator. The bars should take about an hour to 90 minutes to fully set.
  11. Once firm, lift the slab out of the pan and slice into 15 bars. Enjoy!
