Creating Snickers Fudge can be straightforward if you follow these simple steps:

1. Prepare the Pan: Line an 8×8-inch baking dish with parchment paper, leaving some overhang for easy removal later.
2. Melt the Chocolate: In a microwave-safe bowl, combine the semi-sweet chocolate chips and sweetened condensed milk. Microwave in 30-second intervals, stirring in between, until fully melted and smooth.
3. Add Peanut Butter: Stir in the creamy peanut butter and vanilla extract until fully combined and smooth.
4. Layer the Fudge: Pour half of the chocolate-peanut butter mixture into the prepared pan. Spread evenly.
5. Add Toppings: Sprinkle the chopped peanuts and mini marshmallows on top of the first layer.
6. Drizzle Caramel: Drizzle half of the caramel sauce over the peanuts and marshmallows.
7. Add Second Layer: Pour the remaining chocolate-peanut butter mixture over the toppings, spreading it evenly.
8. Finish with Caramel: Drizzle the remaining caramel sauce over the top layer and use a toothpick or knife to create swirls.
9. Chill: Place the pan in the refrigerator for 1-2 hours, or until the fudge is set.
10. Cut and Serve: Once set, lift the fudge out using the parchment paper. Cut into squares and sprinkle with sea salt if desired.

These steps will guide you in creating this amazing fudge effortlessly.
