Chocolate Leaves!

Today we are going to make yummy chocolate leaves! You can eat these leaves afterwards or use them to decorate so scrummy cupcakes! If you do this ensure you send one in my direction!

Whilst making these leaves you can see a little bit of science in action!

You will need:



Rose Leaves

Clean paintbrush

Hot water

Chocolate (Dark chocolate works best!)


Step 1: Go into the garden and pick some rose leaves (or ask Daddy to buy mummy some Roses and pick a few leaves off her bunch!)

Step 2: Get some of your favourite chocolate

How does the chocolate feel?

Would you describe it as a solid, a liquid or a gas?

Step 3: Put some hot water from the kettle in a saucepan (ask an adult for help) and put a clear glass/pyrex mixing bowl over the top. Add in the chocolate and stir

What is happening?

How does the chocolate look now?

What state would you describe it as? Solid, Liquid or gas?

Yummy…liquid chocolate!

Step 4: Once the liquid chocolate is all runny, get your adult to take the bowl off the heat and put it on a table. Get a clean paint brush and paint on the chocolate to the leaves!

What is happening now? Has the chocolate stayed liquid?

Step 5: Once the chocolate has cooled and set into a solid you can peel of the rose leaves, leaving behind the chocolate leaves, to either eat or decorate with! (I would put them in the fridge or freezer for a bit as warm fingers when peeling will melt the chocolate quite quickly!)

Use the leaves to decorate cakes or as a yummy treat!

The Science Bit

This experiment is a great way to demonstrate the process of changing state from Solid to liquid and back again.

Everything we know exists in three states: A solid, A liquid or a Gas!

Substances  can change from one state to another by different processes.





When the chocolate was heated it changes from solid to liquid and that was an example of melting and when we move back from a liquid into a solid it is an example of cooling/freezing.

The reason this happens is because when you provide heat the particles that make up the solid are given energy which cause them to vibrate and then break the bonds holding them together. As they cool they lose this energy and so forms bonds again but not in the same shape…this is why we can mould chocolate and other substances!

Making krispie Cakes is another good way to show this!

    well now I know that cooking with chocolate is educational it would be wrong of me not to do it more! I’ve tried this with leaves, it is very fun to do…shame they’re gone in seconds though!

    Oh – you can eat Rose Leaves??? Wow! How cool! And yes, I think many people forget how the kitchen is a great place to explore science… love the idea of chatting to my kids about science in this context! Thank you.
