1. I used cake crumbs that I got from levelling off the tops of the Traditional Chocolate Cake that I had baked for my daughter's birthday. You can use any leftover cake - vanilla or chocolate sponge. Two medium sized chocolate cupcakes yield 1 cup of cake crumbs. You can also substitute cake with crushed wafers or biscuits - just adjust the consistency of the mixture by adding a few drops of milk at a time in addition to the ganache as wafers and biscuits are dryer than cake. 2. To make 1 cup of chocolate ganache, just place 2/3rd cups of coarsely chopped semi sweet chocolate or choco chips in a bowl and pour 1/3rd cup of cream that has been heated till the bubbles just appear. Cover the pan of chocolate on which the cream has been poured and after a few minutes you will notice that the chocolate has begun to melt. Stir to remove any lumps. 3. Cake sprinkles are available in any cake decorating shop or a well stocked supermarket. I found lovely cake sprinkles by different brands at Lulu supermarket, Carrefour, Wilton stores (Tavola) and Baquer Mohebi here in Dubai.
