How to make fruity pebbles cupcakes

FAQs
Store the leftovers in an airtight container for up to 1 week. If preparing in advance, wait to garnish with cereal until ready to serve.
The cupcakes can be frozen up to 3 months if you need to make these in advance. However, I would wait to frost until ready to serve.
Allow to thaw overnight in the fridge and come to room temperature. Then frost as normal. This is perfect for birthday parties and special occasions when you need extra time.

Tips and Tricks
- Crush the cereal finely. Make sure to crush the cereal before mixing it into the frosting as it will not go through the piping bag without being crushed first.
- Don’t overfill the liners. Be careful that you do not overfill the cupcake liners or you will have a big mess.
- Gently fold in the cereal. Don’t use an electric mixer to combine the cereal. Gently fold in the cereal by hand to combine the ingredients together.
- Allow to cool. Make sure the cupcakes have cooled completely before frosting.
- Clear Vanilla Extract. It is best to use clear vanilla extract. This will give the frosting the brightest hue.
