Line an 8 or 9-inch square baking dish with foil, extending the sides of the foil over the edges of the pan. Mist the foil lightly with cooking spray and set aside.

In a large bowl, beat together the cream cheese, sugar, cinnamon and vanilla with a handheld mixer on medium speed, until combined. Fold in the Cool Whip and set mixture aside.

Lay 8 Oatmeal Creme Pies into the bottom of the dish. Cut the remaining two to fit until there's one solid layer of pies. Drizzle HALF each the chocolate syrup and coffee on top of the layer. Spread HALF of the cream cheese mixture on top. Top with remaining Oatmeal Creme Pies, cutting to fit if necessary. Drizzle with remaining coffee and chocolate syrup, then top with remaining cream cheese mixture. Dust top with cocoa.

Allow the tiramisu to set in the fridge for at least 4 hours or overnight. Flavors develop better overnight. Cut into squares and serve!
