Eat your science with a SWEET activity! Learn how to make edible geode candy using simple ingredients you probably already have! We love edible science experiments because they’re a super fun way to get in the kitchen and experiment with all your senses! Connect with your kids and learn about geology! Let’s make geodes you can eat!
Edible Geodes
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.
If you have a rock collector in the family, this also 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!
What Are Geodes?
First, what are geodes? Geodes are small, hollow rocks that are filled with crystals. They often look like plain, round rocks on the outside, but when you break them open, you’ll find beautiful crystals inside.
These crystals form over a long time, usually when minerals in water seep into the rock and slowly build up layer by layer. As more layers form, they create the shiny and colorful crystals that you see inside geodes.
Geodes can come in different shapes, sizes, and colors, and they are often prized by collectors for their beauty and uniqueness.
Similarly, these 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.

How To Make Candy Geodes
Here’s how to make your own edible geode crystals! Head to the kitchen, roll up your sleeves, and prepare for a fun time with the kids. Kitchen science is the coolest!
Supplies:
- Silicone muffin cups
- Cookie sheet
- Hard candies (like Jolly Ranchers)
- Rolling pin
- Plastic baggies
- Cocoa powder
Instruction:
STEP 1. Preheat the oven to 300 degrees.
Adult supervision is highly recommended with this activity as the candy gets very hot!
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.
TIP: 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!
