Made this to celebrate my brother doing his grade eight piano exam and for my sister's birthday, which was yesterday, by the way. This picture is from the time my brother did his exam, though, not from my sister's birthday.
2 cups graham cracker crumbs
1/3 cup margarine, melted
3 tablespoons sugar
1 1/2 cups peanuts, chopped (reserve half, I forgot to do this)
3/4 cup light corn syrup
1/2 cup chunky peanut butter
1/2 gallon vanilla ice cream, softened slightly (divided in half)
Mix together graham cracker crumbs, butter, and sugar. Press into bottom of 9 x 13 baking dish. Place in freezer for at least 10 minutes to chill.
Blend together peanuts, light corn syrup, and peanut butter. Set aside.
Spoon vanilla ice cream evenly over graham cracker crust. Spread peanut butter mixture as the next layer. Then add the last of the ice cream.
Sprinkle reserved peanuts over the top. Freeze until firm. Remove from the freezer about 15 minutes before serving to soften.
