Recipe FAQs
Can I melt the marshmallows in the microwave?
Yes, you can. Microwave them in a microwave-safe bowl for 1-2 minutes.

This birthday cake popcorn is best enjoyed soon after it's made. We like it best the day it's made, but it's still tasty after a day or two. Longer than that the popcorn will lose its crunch.

Store the popcorn in an airtight container at room temperature for up to two days.
Is this popcorn gluten-free?
It can easily be made gluten-free by using a gluten-free vanilla cake mix.
