HOW TO MAKE GEODES YOU CAN EAT!
ROCK CANDY GEODE
Have you ever seen a geode or other precious stone and thought “I wish I could eat that!”
Now you can! Learn how to make edible geode candy, it’s easier than you think! All you need are some hard candies and a few extra supplies from the kitchen to get started.

These edible geodes would be perfect to serve in class during a lesson on minerals and rocks, or you can have kids make them for a science-themed party! You can also add this to a summer camp activities list.
WHAT ARE GEODES?
Geodes are formed when a liquid mineral solution enters a hollow space inside a rock. Over many years the water evaporates, leaving a crystalized mineral inside the rock.
When the rock is cut open, you can see the crystals inside the rock shell.
Similarly, our edible geodes below are made by melting candy and forming them into a geode shape. But unlike real geodes, these geodes are formed by a liquid turning into a solid, rather than by mineral deposits collected over time.
ROCK CANDY GEODE RECIPE
Here’s how to make your own edible geode crystals! Head to the kitchen, roll up your sleeves, and prepare for a super fun time with the kids. Kitchen science is the coolest!
YOU WILL NEED:
- Silicone muffin cups
- Cookie sheet
- Hard candies (like Jolly Ranchers)
- Rolling pin
- Plastic baggies
- Cocoa powder
HOW TO MAKE GEODE CANDY
STEP 1. Preheat the oven to 300 degrees.
Adult supervision is highly recommended with this activity!
STEP 2. Start by unwrapping your hard candies and place them inside a bag.
STEP 3. Then use a rolling pin to crush the candy into tiny pieces. The kids will love using a rolling pin to crush the candies! It’s great heavy work for busy kids.
STEP 4. Grab your muffin cups and play them on a baking tray.
STEP 5. Next you want to sprinkle a layer of crushed candy on the bottom of your muffin cup. You can use two or three colors to make your candy look more like a real geode.
Have the kids do a little research on geodes and see what you can come up with for neat color combinations. Have you ever broken a real geode?
STEP 6. Heat the candy in the oven for about 5 minutes. You want the candy to be just melted when you take it out. Then take your rock candy geodes out of the oven and let them cool.
STEP 7. Once the candies are hard again, you can pop them out of the muffin cups and coat the edges with cocoa powder. This represents the rock coating surrounding real geodes.
Grab your favorite rock hound book, arrange your geode candy slices on a plate, and enjoy!
If you have a rock collector in the family, this makes an AWESOME geology activity to share together. Science is a neat way to turn off the electronics and connect with kids. Next time you are at the grocery store, toss a bag of hard candies in your cart!
