Instructions
- Prepare pan and ingredients: Line a sheet pan with parchment paper. Measure out peanuts, butter, baking soda, and vanilla, and have them ready.
- Cook sugar mixture: In a medium saucepan, combine sugar and water. Stir in corn syrup. Cook over medium heat, stirring occasionally, until the mixture reaches a gentle boil.
