90 club crackers
1 cup butter
2 cups graham cracker crumbs
1 cup firmly packed brown sugar
1/3 cup sugar
1/2 cup whole milk
1 tsp vanilla extract
1 cup butterscotch chips
1 cup Nutella
Place a layer of the crackers over the bottom of a 9 x 13-inch pan.
In a large saucepan, melt butter over medium heat. Add graham cracker crumbs, both sugars, milk and vanilla. Bring to a boil and boil for 5 minutes, stirring constantly. Remove from the heat.
Spread half the graham cracker mixture over the layer of crackers in the pan. Top with another layer of crackers and spread the remaining half of the mixture over the crackers. Top with a third layer of crackers.
In a small microwave-safe bowl, melt the butterscotch chips in the microwave using short bursts of power. Stir after each burst of power. Stir in the Nutella until smooth, heating again if necessary to reach spreading consistency. Spread the mixture over the top of the last layer of crackers.
Refrigerate until set, at least an hour.
To serve, cut into 48 to 54 bars.
