"This is a fun snack to make. You can also make smaller checkerboards out of just one or two pieces of toast. It is fun to play checkers on the toast squares with grapes or chocolate pieces. You can substitute chocolate cookie butter or another cocoa spread for the Nutella®."
Toast bread slices; remove crusts and cut each slice into 4 squares.
Spread peanut butter over 12 toast squares. Spread chocolate-hazelnut spread over the remaining 12 toast squares. Arrange squares in a grid pattern on a serving plate, alternating chocolate-hazelnut spread and peanut butter topped slices.
