Mason will be 2 this weekend and he loves Mickey Mouse!  Here's what I've made so far for his party.  Unfortunately, the party place doesn't allow you to hang decorations, so I won't be making much.  
Invitations
Birthday parties are so much fun!  Especially when it's your 2nd one!!
Once I got the wording centered, I made these pretty quickly.  I used the Disney Cricut cartridge for the 6" Mickey Mouse head on card stock paper.  The white insert slips out and has the party information in a free Mickey font I found online.

I've yet to the make the big batch for the party. These are the practice ones.
To make these cookies, you will need:
*Double Stuf Oreos
*Mini Oreos
*Black candy writer
*Red candy writer
*Wilton red candy melts
*White confetti/sprinkles
*Wax paper
*Cookie sheet
-Use the black candy writer to "glue" the mini Oreos to the big Oreo
-Place on wax paper and freeze until the candy hardens
-Once dry, use the red candy writer to draw a line across the cookies as the top of the pants
-Melt candy chips as directed and dip cookie to the red line
-Place your "buttons" 
-Place completed cookie on wax paper in the freezer until the pants harden
For the candy writers, I used the BUFF brand from Michael's.  I think the hardest part was finding ears that "fit" correctly.  I had to eat quite a few that weren't *just* right. ;)
