The bug

You can interact with cake in creative mode or when your hunger bar is full.

Fix

BlockCake.java

/**
 * Called when the block is right clicked by a player.
 */
public boolean onBlockActivated(World worldIn, BlockPos pos, IBlockState state, EntityPlayer playerIn, EnumHand hand, EnumFacing facing, float hitX, float hitY, float hitZ)
{
    // Comment: Replaced this
    //if (!worldIn.isRemote)
    //{
    //    return this.eatCake(worldIn, pos, state, playerIn);
    //}
    //else
    //{
    //    ItemStack itemstack = playerIn.getHeldItem(hand);
    //    return this.eatCake(worldIn, pos, state, playerIn) || itemstack.isEmpty();
    //}
    return this.eatCake(worldIn, pos, state, playerIn);
}
