Hazelnut Crispy Cake

Place 4 crispy bars between 2 sheets of plastic wrap; press together into a square. Roll with a rolling pin and shape with your hands into a 5-in. circle. Repeat with remaining 4 bars.

Place 1 circle on a serving plate. Spread top with 1⁄4 cup hazelnut spread. Top with other circle; spread remaining 1⁄2 cup hazelnut spread on sides, then top.

Pat sides of cake with hazelnuts, brushing off any loose nuts. Repeat until sides are coated. To set, let stand at room temperature at least 30 minutes or chill briefly.
