In a large mixing bowl, beat butter with cream cheese, peanut butter, and sugars. Scrape down sides of bowl as needed, and beat for about 3 minutes.
Beat in dry oatmeal until well blended.
Fold in chocolate chips and 2 cups M&M’S® Milk Chocolate candies.
Line a large bowl (about 4 cup size) with plastic wrap. Drop cheese ball mixture into bowl and cover with more plastic wrap. Refrigerate for about 2 hours.
When ready to serve, place chilled cheese ball on serving plate. Press in remaining 2 cup M&M’S® Milk Chocolate candies over the top and sides until completely covered. Add candy eyes if desired.
Serve with graham crackers, cookies and pretzels. ENJOY!
Notes
This can be made a day or so in advance. Just wait to press the top layer of M&Ms and eyeballs into the cheese ball until you're ready to serve it.
Store your cheese ball in the fridge covered in plastic wrap. If you end up with leftover cheese ball (unlikely with how tasty it is), you can reform it into a smaller ball and wrap it in plastic wrap. It won't be as pretty, but it'll still taste good!
