White Chocolate Fudge Rocks

In keeping with the woodland theme, I wanted to decorate my dessert table with various items that you might find on the forest floor– but I wanted to make them edible. Candy rocks immediately came to mind, like the ones I’d used for the Kitty House Cake for a previous birthday party, but the available options were all rather small and I wanted to think bigger. Then I came across a recipe for homemade rocks made of white chocolate fudge– I was sold!

These rocks are really easy to make– you just melt together some white chocolate and sweetened condensed milk, then add cookie crumbs for some realistic speckles and mold the slightly chilled mixture before rolling in powdered sugar. Plus, they look amazingly realistic! I made a half-sheet pan full of rocks with this recipe, including some pretty large ones that I made by wrapping storebought brownie bites (or pieces thereof) in the fudge mixture to bulk them up– I figure that the fudge is sweet enough that no one would want to eat a solid piece of it as big as their fist.

I will note that instead of Oreo cookies or chocolate graham crackers, I used some chocolate cookies that ended up looking too pale for my taste, so I added a spoonful of black cocoa to the crumbs to darken them up. I thought that would work at first, but once I added them to the fudge mixture I realized that the cocoa spread out to color the fudge itself, making it more brown overall than I’d intended. It still looked fine overall, but keep that in mind.

Also, the white chocolate chips I used for my rocks ended up “weeping” a bit of oil once they were melted into the fudge– I’ve read that confectionery coating doesn’t have the same problem, but I didn’t have any on hand. To help fix this I added about 1/4 cup of powdered sugar to the fudge mixture, which seemed to work. The oiliness does recede a bit once the fudge has been chilled, and rolling the finished rocks in more powdered sugar helps a lot.

Anyway, here’s the recipe– you should absolutely try these the next time you need edible decor!

White Chocolate Fudge Rocks (from Hungry Happenings)

  • 24 ounces finely chopped white chocolate or white confectionery coating/candy melts
  • 1 can (14 ounces) sweetened condensed milk
  • 1 pinch of salt
  • 2/3 cup Oreo cookie or chocolate graham cracker crumbs
  • 1/2 teaspoon cocoa powder (optional)
  • Brownie bites or other roundish cookies (optional)
  1. Heat white chocolate, sweetened condensed milk, and salt in microwave for 45 seconds.
  2. Let sit 3 minutes, then stir. Continue heating in 15-second increments, stirring well between each session, until smooth. I only needed two 15-second heating sessions to get things done.
  3. Add 1/4 cup of the cookie crumbs and stir until smooth.
  4. Divide the fudge into 3 bowls and add varying amounts of the remaining cookie crumbs and cocoa powder to achieve different colors of fudge for your rocks. 
  • Press a piece of plastic wrap down onto the fudge in each bowl and chill in the refrigerator for about 30 minutes, until it is thick and no longer sticky.
  • Pinch off varying sizes of fudge, roll into odd shaped balls, and set aside to firm up. If you want to make larger rocks but don’t want to use too much fudge, use a brownie bite or other cookie as a center. Roll in powdered sugar and dust off the excess for a matte finish. Refrigerate on a sheet pan to firm completely, then transfer to a container.
  • These will keep in the refrigerator for a week or two. Store uncovered if you want to let the edges dry out a bit; covered in an airtight container to keep them soft. I personally like them drier so they’re easier to work with.
