Line the pan: Line an 8×8-inch pan with parchment, leaving overhang for easy lifting.
This keeps the base from sticking and gives clean edges.
Soften the dates: If your dates feel dry, soak them in warm water for 10 minutes. Drain and pat dry. Soft dates make a cohesive base.
Pulse the nuts: In a food processor, pulse cashews (or almonds) until finely chopped—like coarse sand.
Don’t over-blend into nut butter.
Make the base: Add dates, shredded coconut, coconut oil, salt, and vanilla. Process until the mixture clumps and holds when pinched. If crumbly, add 1–2 teaspoons water.
Press and chill: Firmly press the mixture into the lined pan in an even layer.
Use the back of a spoon or a flat-bottom glass. Chill while you make the topping.
Blend the mango layer: In a blender, combine mango, coconut cream, sweetener, lime juice, zest, and a pinch of salt. Blend until silky smooth.
Taste and adjust sweetness or lime.
Set with gelatin or agar:
For gelatin: Sprinkle gelatin over 3 tablespoons cold water. Let bloom for 5 minutes. Warm gently in a small saucepan until melted (do not boil).
Whisk into the mango mixture.
For agar: Whisk agar into 3 tablespoons water. Bring to a gentle simmer for 1–2 minutes, stirring until dissolved. Immediately blend into the mango mixture.
Assemble: Pour the mango mixture over the chilled base.
Tap the pan to release air bubbles. Sprinkle shredded coconut evenly on top.
Chill to set: Refrigerate for at least 3–4 hours, or until firm enough to slice. For the cleanest cuts, chill overnight.
Slice and serve: Lift out using the parchment, then cut into bars with a sharp knife.
Wipe the blade between cuts for tidy edges.
