These no-bake cookies are wonderful. I love them around Christmas time.
Ingredients:

1/2 cup brown sugar
1/3 cup light corn syrup
1 teaspoon vanilla (I have used as much a 1 tablespoon and have liked the results)
3/4 cup peanut butter
3 cups ready-to-eat cereal flakes (I use Frosted Flakes)
1 cup coconut flakes (optional but in everyone of mine I make)

Directions:

1. Combine in saucepan and heat to boiling:

• 1/2 cup brown sugar
• 1/3 cup light corn syrup 

2. Stir in:

•  1 teaspoon vanilla 
• 3/4 cup peanut butter 

3. Mix until smooth stir in:

• 3 cups ready to eat cereal flakes 
• 1 cup coconut 

4. Drop by teaspoonfuls onto waxed paper. Sometimes I need to squeeze them together with fingers. Let cool and eat!
