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.
