Valentine’s day school parties are one of my favorite memories from my days in elementary school. I loved picking out my Valentine’s day cards, picking out a fun treat to pair with them, and passing them out to friends at our class party. I would always pick out the valentine cards with the perfect messages for the most special people…if you know what I mean. 😉 As a mom of littles one of the best things is getting to help plan the school party, decorate with cute hearts and bring in sweet treats.
These adorable Valentine Monster Cookies are the perfect easy treats for your kiddos and their classroom. Peanut butter, oats, chocolate chips all of your favorite cookie ingredients rolled into into these valentine treats. We turn typical Monster cookies into festive treats with the addition of pink, white and red M&Ms.
You could even add a few colorful sprinkles that tie into the Valentine’s Day colors to these delicious cookies. Customizing colors in your favorite treats like simply switching out the M&M colors, is the perfect way to make them fit a theme without making big changes.
