9 c. Crispix cereal
1 c. mixed nuts
1 c. packed brown sugar
1/2 c. butter
1/2 c. corn syrup
1 tsp. vanilla extract
1/2 tsp. baking soda
2 c. M&M'S®
1 1/2 c. raisins

Preheat oven to 250 degrees. Combine cereal and mixed nuts in a large roasting pan.

In 2-quart saucepan over medium heat, heat brown sugar, butter, and corn syrup to boiling while stirring. Without stirring, boil 5 minutes. Stir in vanilla and baking soda. Pour over cereal mixture; stir until pieces are evenly coated. Bake 1 hour, stirring every 15 minutes.

Cool completely, stirring frequently to break mixture apart. (I have found that pouring mix into a large plastic bowl works best to prevent sticking to the pan as it cools.) Stir in M&M'S® and raisins.
