In a food processor, combine dates, almonds, almond butter, vanilla extract, and a pinch of salt. Process until the mixture comes together and resembles a sticky dough.
Press into Pan:
Line a square baking dish with parchment paper. Press the nougat mixture evenly into the bottom of the dish. Place it in the freezer while you prepare the next layer.
Make the Caramel Layer:
In the same food processor (no need to clean it), combine dates, almond butter, melted coconut oil, vanilla extract, and a pinch of salt. Process until smooth.
Add Peanuts:
Stir in the roasted peanuts into the caramel mixture.
Layer Over Nougat:
Spread the caramel and peanut mixture over the nougat layer in the baking dish. Return it to the freezer and let it set for at least 1-2 hours.
Chocolate Coating:
Mix the melted dark chocolate with coconut oil. Remove the dish from the freezer and pour the chocolate mixture over the caramel layer, spreading it evenly.
Freeze Again:
Place the dish back in the freezer and let it freeze until the chocolate is set.
Cut into Bars:
Once completely frozen, lift the frozen Snickers out of the dish using the parchment paper. Place it on a cutting board and cut into bars.
Serve:
Keep the bars stored in the freezer. When ready to eat, let them sit at room temperature for a few minutes to soften slightly.
