No-Bake Peanut Butter Cornflake Cookies
Ingredients
* 1 cup granulated sugar
* 1 cup light Karo corn syrup
* 1 cup creamy peanut butter (Jif or Skippy)
* 1 teaspoon vanilla extract
* 6 cups Kellogg's Corn Flakes cereal
Instructions
1. Line two large baking sheets with parchment paper or wax paper. Have all your ingredients measured out and ready, as this recipe moves quickly.
2. Place the 6 cups of Kellogg's Corn Flakes in a very large, heat-proof mixing bowl and set aside.
3. In a medium saucepan, combine the granulated sugar and light Karo corn syrup.
4. Cook over medium-high heat, stirring frequently, until the mixture comes to a full rolling boil.
5. As soon as it boils, immediately remove the saucepan from the heat.
6. Stir in the creamy peanut butter and vanilla extract. Keep stirring until the peanut butter is completely melted and the mixture is smooth and cohesive.
7. Pour the hot peanut butter mixture directly over the cornflakes in the large bowl.
8. Using a large rubber spatula or wooden spoon, gently fold the mixture together until every single cornflake is completely coated, being careful not to crush the cereal too much.
9. Working quickly before the candy sets, use a cookie scoop or two spoons to drop clusters of the mixture onto the prepared baking sheets.
10. Let the cookies cool at room temperature for about 30 minutes until they are totally firm and set.
