Everton, the love to cook store, has a sale on their Easter bunny chocolate mould range, which includes 3 moulds. I have such good memories of making chocolate moulds with my mum, its something I'd love to continue with my own children.
You can buy the Silikomart Easy Choc Easter Chocolate Moulds for $12.95 reduced from $19.99, or the Nordicware 3D Bunny Pan reduced from $69.00 to $35.95, perfect for a desert table centerpiece. Alternatively, there's also the 3D Cottontail Bunny Pan which was $88.00 but down to $57.95.
Admittedly these will cost you a little more than just going down to Big W for your Easter Egg, but if you have a lot of bunnies to give, or simply fancy making your own, these are lovely, good quality pans.
The silicone pan is from Italy and is guaranteed for 3000 uses, and the cast aluminum is non-stick and made in the US.
There's a $6.90 fixed rate shipping fee in Australia, so you can buy as many as you like without paying heavy postage.
