i think i got this recipe off of a shreddies box years ago.
super delicious and easy to make.
6 cups popped popcorn
6 cups shreddies
1 cup salted peanuts (i like the ones without skin)
1/2 cup margerine/butter
1/2 cup smooth peanut butter
1 package of large marshmallows (250 g)
mix it up:
toss together popcorn, shreddies and peanuts.
melt butter and peanut butter in a large microwave bowl (about a minute)
add marshmallows and microwave for another minute until marshmallows puff.
stir in cereal mix until well coated
pour into 2 greased 15"x10" (or whatever's handy - i know i've used random sizes)
bake at 250 F for 10 minutes
break into bite sized pieces and store in an airtight container.
