Prepare the Optional Crust: In a food processor, pulse together 1 cup of almonds or cashews, ½ cup of shredded coconut, and 5 Medjool dates until the mixture clumps together nicely. Drizzle in 2 tablespoons of melted coconut oil and a pinch of salt, blending until well combined. Once clumpy, press this mixture evenly into the bottom of an 8x8 inch pan lined with parchment paper. Chill in the refrigerator for about 30 minutes while you prepare the filling.

Make Chia Pudding Filling: In a mixing bowl, whisk together 1 cup of full-fat coconut milk, ¼ cup of chia seeds, 2 tablespoons of maple syrup or agave, the zest of 1 lime, and the juice from that lime along with 1 teaspoon of vanilla extract. Sprinkle in a pinch of salt to elevate the flavors. Let this mixture sit for 5-10 minutes; you'll notice the chia seeds begin to absorb the liquid and thicken, transforming into a creamy pudding-like texture.

Combine Layers: Once your chia pudding has thickened to your liking, carefully pour it over the chilled crust in the 8x8 inch pan. Use a spatula to smooth out the top, ensuring an even layer of the pudding. Cover the pan with plastic wrap or a lid and refrigerate for at least 4 hours, but preferably overnight, to allow the bars to firm up perfectly.

Finish and Serve: After chilling, remove the pan from the refrigerator. Using the parchment paper, lift the entire block of chia pudding out of the pan. To make your bars extra special, sprinkle the top with toasted coconut and extra lime zest for a burst of flavor. Slice into squares or bars, and enjoy your delicious No-Bake Chia Pudding Bars with Zesty Coconut Lime Flavor as a refreshing snack or dessert!
