This candy-studded tart is like a giant homemade Reese’s cup, complete with Kit Kats, Candy Corn, and Reese’s Pieces, too. It’s an absolute must if you’re hosting a party this year, or for bringing to your co-workers as a sweet and festive treat. A combination of Oreo cookies and melted butter form the super-simple base, which is topped with a creamy peanut butter center and a silky-smooth chocolate ganache. Feel free to use any candy you have on hand, but be sure to choose at least one variety that will add a pop of color. Chill until firm (which will make it easier to slice), then dig in.
