Preparation

1. Line a cookie sheet with parchment paper and arrange crackers in a single layer.
2. In a small saucepan, combine sweetened condensed milk, butter, and brown sugar. Cook over medium heat for 7-8 minutes, stirring often.
3. Reduce heat to low and whisk in milk, vanilla, and peanuts until smooth. Cook for 2 additional minutes or until mixture is thick, then remove from heat.
4. Use a cookie scoop to top each cracker with the caramel mixture.
5. Allow cookies to fully cool, then store in an airtight container.
