These Halloween monsters are a ton of fun to make – albeit it is messy (you’ve been warned!). I tried my best to use natural ingredients along the way for the base, colouring, and eyeballs.
The base is super simple and only requires 3 ingredients (natural peanut butter, natural sweetener – we used maple syrup, and rice cereal). Thank you to The Big Man’s World for this 3 ingredient recipe! Using a 9 x 13 inch pan, we cut them into 18 squares but I would even recommend half this size to make them more kid-friendly! Especially if you want fun finger food at a party or get-together.
I was determined to make natural food dye for this recipe and I was surprised at how easy it really was! I chose 3 colours for the monsters: red (beets), purple (purple cabbage), and blue (purple cabbage dye + baking soda). See the details in my DIY: Natural Food Colouring (Blue, Red and Purple) blog post.
You simply replace the liquid in your icing recipe with these naturally colourful liquids and ta-da!
Apply the colourful icing to the top of the square and let it drip down (rather than applying and spreading it with a knife). I did spread it a little bit but tried to let it drip on it’s own to get a more smooth look.
Before adding the eyeballs (Greek yogurt + mini choco chip), I placed them in the freezer for about 1 hour. As the icing was dripping quite quickly, I placed them in the freezer one by one as they were made.
I suggest serving these frozen because they melt quickly!
Serves: 18 or more
Rice Krispie Square
8 cups rice cereal
2 cups natural peanut butter (only ingredient in the ingredients list is peanuts!)
2 cups natural sweetener (we used maple syrup)
mini chocolate chips
Amount of each “eye ingredient” will depend on how many eyeballs you want your monsters to have (use your imagination!)
Natural Food Colouring (used as liquid in icing recipe)
3 cups water
1 cup red cabbage leaves
1 cup diced beets
1 tbsp baking soda
Rice Krispie Squares
- Make the rice krispie squares by placing the rice cereal in a large bowl and setting it aside.
- Add the peanut butter and maple syrup to a large pot and simmer as you mix it until it is combined.
- Then add the sticky mixture to the rice krispies and combine with your hands.
- Add the mixture to a 9 x 13 inch pan and place in the refrigerator overnight. Make sure it is very sticky and fits tightly in the pan.
- Make the eyeballs by placing drops of yogurt on parchment paper and add a mini chocolate chip on top.
- Place them in the freezer for at least 1 hour.
Natural Food Colouring (see blog post for more details)
- Make the red food dye by boiling 5 diced beets in 1 cup of water
- Make the purple food dye by boiling 2 cups of purple cabbage leaves in 2 cups of water
- Make the blue food dye by taking half the purple food dye and adding anywhere from a pinch to 1 tbsp of baking soda, and mixing it until it becomes blue
Putting it all together!
- Once your rice krispie base is made and refrigerated, the eyeballs are frozen and the food colouring is prepared, you can have some fun making your monsters!
- Replace the liquid in your icing recipe with the natural food colouring of choice. Mix well until the icing is the colour you are going for!
- Place the icing on the squares by letting it drip down from the top and slightly spreading it with a knife.
- Place the eyeballs on the monsters and place them in the freezer on parchment paper immediately.
- Let the monsters freeze overnight!
- Serve frozen and enjoy!
