Preheat the oven to 180 C (350 F). Line a 23-cm (9-inch) square baking pan with parchment paper and spray with cooking spray.
Prepare the cookie base: Spread pecans on a baking sheet and bake for 5 minutes, or until lightly toasted. Cool, then reserve 16 pecan halves for the top and finely chop the rest. In a mixing bowl, combine almond flour, corn-starch, coconut oil, agave and half of the chopped pecans. Stir until combined. Press the mixture evenly into the prepared pan. Bake for 15 to 17 minutes, or until lightly golden brown. Remove from oven and set aside to cool.
Prepare the caramel layer: If the dates are firm or dry, soak them in hot water for 5 minutes, then drain and pat dry. In a food processor, combine dates, almond butter, agave, vanilla extract and sea salt. Pulse in short bursts, scraping down the sides as needed. Add water, 15 mL (1 Tbsp) at a time, pulsing between each addition until smooth. Spread caramel evenly over the cooled cookie base. Top with remaining chopped pecans. Transfer to the freezer for 30 minutes.
Prepare the topping: Microwave chocolate chips and almond milk in a microwave-safe bowl for 60 seconds, and then stir until creamy. Spread most of the melted chocolate over the caramel layer, reserving 30 to 45 mL (2 to 3 Tbsp) for drizzling.
Arrange the reserved pecans on top and drizzle with the remaining chocolate. Sprinkle with flaky sea salt, if desired. Return the pan to the freezer for another 10 minutes to set the chocolate. Cut into squares and serve. Makes 16 servings.
