Energy Bars

2 1/2 cups oatmeal
2 1/2 cups rice krispies
1 1/2 cups raisins
1 cup unsalted peanuts
1/2 cup peanut butter
1/4 cup butter
1 10-oz pkg marshmellows (or 5 cups mini)

Mix the first 4 ingredients in a large bowl.  Melt the peanut butter, butter, and marshmellows in the microwave for 1 minute.  If not melted completely, keep microwaving in 10-second times until melted.  Add dry ingredients and stir quickly.  Spread onto greased or waxed-paper-lined cookie sheet.  Use a buttered spoon to spread.  Cool and cut into squares.  These freeze well for later use.
