What Makes Monster Rice Krispie Treats So Fun
The beauty of Monster Rice Krispie Treats is that there are no rules.
Your monster can have:
• one eye
• three eyes
• ten eyes
• crooked teeth
• vampire fangs
• a goofy grin
The sillier the better.
Some monsters look scary.
Some look adorable.
Some look like they just woke up from a nap.
And honestly?
Those are usually the cutest ones.
Decorating these treats is half the fun, especially for kids.
Kids love adding candy eyes, colorful frosting, and goofy expressions to make each monster unique.
Which means this recipe isn’t just dessert.
It’s an activity.
I had grand plans of Homemade Apple Cider, a fabulous meal of Slow Cooker Chicken Taco Chili, delicious dessert, and festive gifts. Reality settled on Crockpot Taco Soup made from whatever I could find in the pantry, rice Krispie treats that I didn’t have the right food coloring for, and two little books for Cooper wrapped in pre-used wrapping paper. A classic it’s-the-thought-that-counts moment. It was still fun!
I meant to make these pumpkin-shaped rice Krispy treats from Cincy Shopper, but found out a little too late that I didn’t have any red food coloring to make orange. I improvised and made green monsters! My one-year-old loved them. Plus they were super simple and easy which is exactly what I needed.
