In this super, fun, easy and inexpensive tutorial, we are going to make a Gold Mine Edible Excavation that the young Excavating Adventurers in your life will love. This Gold Mine Edible Excavation takes the good old fashioned Rice Krispies Treats recipe, but we add a fun Excavating Adventures spin. We’ll take this tasty treat and turn it into a delicious gold mine to explore and discover the yummy gold nuggets we have hidden inside.


Excavating Adventures Pro Tip: Use this edible excavation to create some fun and excitement around topics or lessons concerning gold, The Gold Rush, mining, and more!



6 Tbsp salted butter

6 cups mini marshmallows – Mini marshmallows melt easier than the larger ones.

1/2 tsp vanilla extract

4 cups Cocoa Rice Krispies cereal

Pack of M&Ms

Edible gold spray

Wax paper

13 x 9 x 2-inch pan

Measuring cups and spoons


Cooking spray

Plastic spoons, forks, and knives. These will be the excavation tools.



  1. Place M&Ms on the wax paper and spray with the gold spray.
  2. Flip the M&Ms over and spray the other side to make your gold nuggets.
  3. In large saucepan melt butter over low heat.
  4. Add the mini marshmallows and stir until completely melted. Remove from heat.
  5. Add the Rice Krispies cereal. Stir until well coated.
  6. Coat the 13 x 9 x 2-inch pan with cooking spray.
  7. Using a buttered spatula or wax paper, evenly press a thin layer of mixture into the pan.
  8. Quickly scatter the gold painted M&Ms in the pan and press another layer of Rice Krispies mixture on top.
  9. Allow to cool.
  10. Cut into 2-inch squares. The Gold Mine Edible Excavation is best if served the same day.
  11. Distribute the “excavation tools” and encourage the Excavating Adventurers to dig in and discover the gold nuggets as they become prospectors for the day.
