In a bowl, mix the sweetened condensed milk, coconut and vanilla. Spoon the mixture onto the crust, spreading gently, so you don't distrub the crust.
Bake for 20-25 minutes, until the coconut is a nice golden brown.
Melt the chocolate in the top of a double boiler, or in the microwave. If using a microwave, use short intervals of 30 seconds or so, stiring between intervals, and removing from microwave when the chocolate is almost, but not fully melted. Stir until fully melted.
Spread the melted chocolate over the baked coconut bars.
Sprinkle the remaining 1/2 cup toasted almonds on top chocolate.
Place coconut bars in the refrigerator for about 1 hour, until chocolate has hardened.
When fully chilled, remove entire dessert from the pan by pulling up on the foil liner. Slice into bars, using a sharp knife, cleaning the knife (with warm water) between cuts if you want nice, sharp bars.
Bars may be served at room temperature, or directly from the fridge. Store remaining bars in the refrigerator, wrapped well. Can be made 2-3 days in advance.
