Prepare the Pan: Line a baking sheet with parchment paper to prevent sticking and for easy cleanup.
Cook the Syrup Mixture: In a medium saucepan over medium heat, combine the maple syrup, heavy cream, and butter. Stir occasionally until the mixture comes to a gentle boil.
Simmer: Once boiling, reduce the heat and simmer for 10-12 minutes, stirring frequently, until the mixture thickens to a soft, candy-like consistency. If using a candy thermometer, aim for a temperature of 240°F (115°C).
Add Vanilla and Peanuts: Remove the saucepan from heat. Stir in the vanilla extract and sea salt (if using). Then, add the peanuts and mix until well coated.
Form the Goodies: Spoon small mounds of the peanut-maple mixture onto the prepared baking sheet. Let them cool and set at room temperature for about 30 minutes.
Optional Chocolate Drizzle: If you’re adding a chocolate drizzle, melt the chopped chocolate in a microwave-safe bowl for 30-second intervals, stirring in between until smooth. Drizzle over the cooled Maple Nut Goodies for a rich, sweet finish.
Cool Completely: Allow the goodies to cool completely before serving or storing.
