Let the ganache cool to lukewarm before you use it. If it's too hot, it will simply absorb into the cake and disappear.

Ingredients

Makes about 2 1/2 cups

　　1 stick (1/2 cup) organic unsalted butter

　　Two 7-ounce bars organic 70% baking chocolate (or for real dark-chocolate lovers, use unsweetened chocolate)

　　2 cups organic semisweet chocolate chips

　　

Step 1

Place the butter and chocolate in the top of a double boiler or in a stainless-steel bowl placed over a saucepan one-quarter full of water. Over medium-high heat, stir the mixture frequently with a rubber spatula until the chocolate is almost melted. Remove from the bottom pan and stir until the chocolate has finished melting.

　　

Step 2

Cool for 15 minutes or more, until thickened, before using.
