Prepare your baking sheet by lining it with parchment paper.

In a medium saucepan over medium heat, combine the granulated sugar and unsalted butter, stirring continuously for about 5 minutes until melted and smooth.

Allow the mixture to boil without stirring for 5 minutes until it turns golden amber.

Remove from heat and carefully stir in the heavy cream until combined.

Add the chopped mixed nuts, vanilla extract, and sea salt, stirring well.

Pour the mixture onto the prepared baking sheet, using a spatula to spread it evenly.

While warm, sprinkle the crushed cookies over the praline mixture.

Melt the dark chocolate chips and drizzle over the mixture.

Melt the white chocolate chips and drizzle over the dark chocolate layer.

Optionally, sprinkle a pinch of cinnamon over the chocolates.

Let the mixture cool completely for at least 1-2 hours until hardened.

Break into pieces and store in an airtight container at room temperature.
