1Preheat the oven to 350F.
2In a small bowl, stir together the coconut, sugar and egg whites. Spray a small tart pan or mini muffin pan with nonstick spray and press about a tablespoon of the coconut mixture into each, gently pressing into the bottom and up the sides. Bake for 10 minutes, or until golden. Set aside to cool, but use a thin knife to run around the edge of each and remove it from the pan while it's still warm.
3To make the ganache, warm the cream in a small saucepan until steaming. Add the chocolate and let sit for a few minutes, then whisk until smooth. Spoon into the cooled tart shells and refrigerate until it firms up - top each with a chocolate egg.
4Makes about 2 dozen tarts.
