According to Foodimentary -- a website that keeps track of food holidays -- today is World Nutella Day. Nutella, a creamy combination of cocoa and hazelnuts, is best known as a dip or spread, but it actually has many other uses. You can add Nutella to cakes, cookies, pies, candies, ice creams and frostings too! It's also an ingredient in beverages, both alcoholic and nonalcoholic.
I use a spring-form pan, but you can use a 9-inch square pan or layer the ingredients in a pretty glass bowl. Depending on the size and shape of the pan you use, you may need more or less cookies.
You don't have to measure the filling, but make sure you leave enough to completely cover the top of the cake. The cake needs to be refrigerated overnight to firm up.
If you want to dress it up even more, add a dollop of whipped cream,
a sprinkling of chopped leftover Nutter Butters
and top with additional chocolate syrup.
