Easy Toddler Halloween Treats


These Rice Krispise Monsters are the perfect Halloween treat. They are made using Rice Krispies and marshmallows. The beauty of them though is they can be decorated in using any colours and in any way you want.

Reasons to Love This Recipe

These Rice Krispie Monsters are so adaptable you can use Gluten Free Rice Krispies or Dairy Free Spread instead of Butter. You can also use Dairy Free Chocolate to decorate them with. They are so adaptable. They also don’t contain any eggs.

As well as being able to adapt the ingredients for your dietary requirements you can also adapt how the monsters look. I went for a simple design of using white chocolate and food colouring and some edible eyes. But you can be as creative as you want. Why not give them hair or little faces the possibilities are endless.

They are the perfect treat for adults and kids alike. Why not get your child/children involved in making these. They will have a great time designing their own little monsters.

Rice Krispie Squares

To make the Rice Krispie squares start by adding the marshmallows to a large saucepan. I used a mixture of pink and white marshmallows, but you could use either all pink or all white.

Add the butter, and melt slowly on a low speed, stirring continuously so that they don’t burn. Once the marshmallows are completely melted remove from the heat and add in the Rice Krispies.

The mixture will be pretty sticky but mix the Rice Krispies through until they are completely coated in marshmallow.

Pour the mixture into your pre-prepared tin. A top tip, if you coat your hands in a little butter it will stop the marshmallow from sticking to you and make it a lot easier to press it into the tin.

Pop the mixture into the fridge for 1-2 hours to allow the marshmallows to set.


Once your Rice Krispies have completely set, take them out of the fridge and cut them into individual portions. I decided to make mine different sizes so that they were all a little different, but you can make them all the same size if you prefer.

Once you have cut them into individual portions leave to one side. In a bowl add the

white chocolate and melt in the microwave on 20 second bursts stirring in between each burst until it is completely melted and smooth.

Split the chocolate into three separate bowls. Again, this depends on how many different colours you are wanting to use. I went with three: orange, purple and green, but you can use as many or as little colours as you want.

Once you have split the chocolate into the individual bowls add the food colouring. You need to add the food colouring a little at a time stirring in between each addition. If you add to much to begin with then you are stuck with that colour there is no way to lighten it.

As I said you can use any colour of food colouring you fancy just ensure that it doesn’t contain any water. If it contains water, then it will end up seizing the chocolate.

Once all your bowls of chocolate have been coloured you can start dipping your monsters in. I just dipped one quarter of them in but again this is completely up to you. You could dip the entire monster or half. Once you have dipped them into the chocolate place them onto your lined baking tray.

Now all your monsters have been dipped in chocolate you can decorate them using edible eyes, sprinkles, crushed Oreos or any other edible decoration to make them look as cute or as scary as you can.


As I said above there are so many different alternatives for this recipe from using Gluten Free Rice Krispies to Dairy Free Spread and Chocolate.

There are also lots of different ways to decorate the monsters. I went for simple edible eye but let your and your children’s imagination run wild.
