Whisk together the flour, baking soda, and salt in a medium bowl. Set aside.

Using a mixer, cream the softened butter, granulated sugar, and brown sugar until light and fluffy. Add the egg and vanilla extract, and mix until well combined.

Gradually add the flour mixture to the wet ingredients, mixing until just combined.

Gently fold in the chopped Snickers bars, dry roasted peanuts, and chocolate chips.

If the dough seems too dry, you can add an additional tablespoon of softened butter or a splash of milk to bring the desired consistency.

Using a spoon or cookie scoop, drop rounded tablespoons of cookie dough onto the prepared baking sheet, leaving some space between each cookie.

Place the cookie sheet into the fridge for at least 1 hour.

Preheat your oven to 350°F (175°C).

Bake for 10-12 minutes or until the edges are golden brown.

Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Once the cookies have cooled, warm up the Nutella in the microwave for about 20-30 seconds until it's pourable but not too hot.

Drizzle the warmed Nutella over the cooled cookies using a spoon or a piping bag.
