Unicorn Rice Krispie Treats INGREDIENTS

To make these Unicorn Rice Krispie treats, you need only a few ingredients on hand:

  • You will need 5 cups of puffed rice cereal. Either Rice Bubbles or Rice Krispies are perfect (they are also the same thing, depending on where you live).
  • You need 1 large bag of pink marshmallows. This is what holds together your Rice Krispie treats. By using pink marshmallows, you will get a pink slice, however, you can substitute with white marshmallows instead and use a few drops of pink food colouring to get the pink shade.
  • You will also need 1 pack of white chocolate melts. These are melted and used for dipping your unicorn treats to make them look extra fancy.
  • And, the final ingredient is 100s and 1000s or rainbow coloured sprinkles. Dip your bars straight into the sprinkles before your chocolate sets to give them a beautiful rainbow look. You can use a single colour sprinkles instead if you are going for a different themed look.

How to make unicorn rice bubble bars

tips for making the bars

Recipes with marshmallow can be sticky business. Especially when you are trying to get your mixture to stay firm in your baking tray.

They need to be pressed firmly into the tray to avoid a crumbly mess.

Here are my favourite tips to make this easier (and to help you avoid ending up with sticky marshmallow mixture up your arms):

  • Once your mixture is poured into the pan, spray your hands with cooking oil spray
  • This will allow you to press down on your mixture without them sticking to your hands
  • Use your hands to firmly press your mixture into the tray, right to the corners to ensure it is tightly packed

These unicorn Rice Bubble bars are best kept in the refrigerator in an airtight container. This stops the chocolate melting.

They will keep fresh in the fridge for about a week (although it’s unlikely they will last that long!)
