Peanut Butter Rocky Road Bars.

I always think of my Nan Morgan whenever I make these Peanut Butter Rocky Road Bars. It was one of those treats that she always seemed to have on hand.

Desiccated coconut in white ceramic bowl.

Fine cut dried (desiccated) unsweetened coconut is the type I use in this recipe, but any kind is fine.

I remember she made these in a plain version with a can of Fussell’s thick cream stirred into melted chocolate too. All 24 of her grandchildren must have eaten thousands of those over the years in her kitchen in Port-de-Grave.

I also remember this version which she made in later years but I don’t recall her ever using the peanuts in it. That was my addition because Im partial to a change in textures and tastes.

Marshmallows in a clear glass measuring cup.

I like plain mini marshmallows in this recipe but some folks do use coloured marshmallows too.

You can easily leave them out if you like. If you are a person who likes the salty-sweet combination, try using salted peanuts instead! I love that too.

Dark Chocolate Chips, to melt and dip the biscotti

I like to use 50% dark chocolate chips for this recipe but you can use semisweet as well.

Another old favourite from Nan’s kitchen in addition to these Peanut Butter Rocky Road Bars.

For another no-bake treat, one of our most popular recipes of the last 14 years comes from Nan Morgan’s kitchen as well. In the lead up to Christmas, it becomes even more popular because they are so freezer-friendly.

If you freeze them, they can even be made weeks in advance. Give Nan’s fudgey chocolate Snowballs a try too.

Peanut Butter Rocky Road Bars . A quick & easy, no bake, old fashioned favourite with marshmallows suspended in a luscious combination of peanut butter and chocolate; with the crunch of roasted peanuts too, if you like.

Ingredients

  • 1/3 cup butter
  • 3/4 cup smooth peanut butter
  • 2 cups chocolate chips
  • 10 oz bag mini marshmallows, 250g
  • 1 cup roasted peanuts, optional
  • 1/2 cup dried unsweetened or sweetened coconut, optional

Instructions

  1. Lightly grease a 9x9 pan and line with parchment paper. You can dust the bottom with 1/4 cup of the coconut if you are using it.
  2. In a medium saucepan, melt the butter and peanut butter together, then melt in the chocolate chips. As soon as the chocolate chips are melted, take it off the heat. You do not want to overheat this mixture.
  3. Add the marshmallows and peanuts to a large mixing bowl.
  4. Pour in the chocolate mixture and fold until the marshmallows are all covered in the chocolate mixture.
  5. Spread into the prepared pan and sprinkle the other 1/4 cup of dried coconut on top if you are using it.
  6. Chill for 3-4 hours before cutting into squares or bars. I find that a serrated bread knife works well.
  7. Store in airtight containers. These will freeze quite well.

Notes

Use salted peanuts for a sweet and salty version; one of my faves!

These are quick and easy to make, delicious and great after freezing. I skipped the coconut and used natural peanut butter (no salt or sugar added) and salted peanuts. Very sweet, so I cut into small, 2-bite squares.

[…] I decided to include this no-bake fudge version in the series to make it easier.  I couldn’t find my mom’s recipe, so I took inspiration from Barry Parsons at Rock Recipes.  You can find his original recipe here: Peanut Butter Rocky Road Bars […]
