Pre-heat the oven to 180C.
Line a 25cm x 25cm tin with baking paper.
Melt the chocolates, butter and sugar together over a low heat.
Once they are melted, remove from the heat and leave to cool for 5 or 10 minutes.
Beat in each egg, one by one.
Stir in the flour.
Put half of the batter into the base of the tin and spread out.
Chop 4 of your MaltEaster Bunnies into chunks and sprinkle evenly over the brownie batter.
Spread the rest of the batter on top to cover the chunks of MaltEaster bunnies and smooth out with a spatula.
Sit your frozen, unwrapped (obvs!) bunnies evenly on the surface of the brownies.
Bake for about 20 minutes. A skewer should come out only just clean. You could test at 17 minutes and again at 20 minutes just in case.
As always, remember that depending on your oven it could take up to 10 minutes longer, but please please try not to overcook them. Brownies are always better under-done than over.
