First, cut the cake in half.
Put a little frosting on the plate to hold the cake on, and between the two pieces of cake to hold them together. I put the top of the cake facing out since the bottom is flatter and the pieces will fit together better. Then cover the whole thing in frosting. It doesn't have to be nice, you're going to add fur later.
Cut out a notch and frost the cut areas. Eat the notch!
Toast some coconut in the oven on 350F or in a nonstick frying pan over medium heat until it looks like this. Cool completely.
Cut 1 large marshmallow in half diagonally for the ears.
These are the ears.
Cut another marshmallow in half for the cheeks.
Place the ears on top of the notch you cut out earlier. Press the cheeks onto the face and use jelly beans to make eyes and a nose. Use 2 small marshmallows for teeth .
And one more big one for a tail.
Put your coconut on a large tray so you can re-use it to fill in other parts of the bunny. Use your hands to press the coconut all over covering your bunny completely. Put the leftover coconut into a zipper bag and add a few drops of green food colouring. Seal the bag and shake it until the coconut turns green.
Use the green coconut as grass and add a few eggs for decoration . I had some coloured sugars and since the cut side of the ears were sticky I used the sugar to add a little sparkle. I also sprinkled some in the grass.
Refrigerate until ready to eat. You could make the cake a few days in advance but I would probably frost it no more than a day ahead of time.
