12 ice cream sandwiches
4 c whipped cream
1 c peanut M&Ms, crushed
3 Butterfinger candy bars, crushed
1/2 c chocolate syrup.
Line up 4 ice cream bars in pairs (making a square). Spread a 1-c layer of whipped cream on top.
Sprinkle on half the crushed candy. Layer 4 more ice cream sandwiches cross-wise, log cabin style. Spread on another 1-c layer of whipped cream and the rest of the candy.
Add another layer of ice cream sandwiches the same direction as the first layer. Spread remaining whipped topping and drizzle with chocolate syrup.
Cover with plastic wrap and freeze at least 3 hours.
